This is a copy of something I got sent to me. I don't vouch for any of the info vin it. I think some of it flys in the face of the general consencious of oppinion. However as a lot of the 'veg oil' stuff about seems to be based on conjectur and personal opinion, i guess this could be as much use as anything els. Hope it helps someone out there...

In Defence of Homemade ?Diesel?
Your reported that labour MP Rob Marris has been blaming on the use of
unauthorised biofuels, such as biodiesel made from waste cooking fat. Does he not
realise that bio diesel is is fact a much cleaner fuel than ordinary diesel.
According to the US Environmental protection agency, bio diesel reduces carbon
monoxide emissions by some 50%, unburnt hydrocarbons by 93%, particulate matter
by 30% and mutagenicity (The ability to mutate genes) by 80 to 90%.
It is renewable since the material comes froma farm. High quality biodiesel can be
made by individuals and small businesses, and if you make your own fuel you will not
be stuck if there is another fuel blockade.
It appears as though Marris is trying to shut down home producers with the effect of
forcing motorists to go back to buying fossil fuels form the big oil companies. This
would cause an increase in air pollution, exactly the opposite of what he claims to
want.

Willie, driving off the fat of the land.
Veteran country singer Willie Nelson has a new hit on his hands?? A diesel fuel
made from recycled vegetable oil collected from the deep fat fryers from burger bars.
The 72 year old Texan has set up a company to market the eco friendly product and
hopes to market it around the world.
He calls it Bio Willie and says that the best thing about it is the exhaust pipe of his
£75,000 Mercedes always smells of chips.

Yep, forget about handing your hard-earned coffers over to the corrupt, greedy and
killing corporations like Shell and BP, take a squeezy bottle, a piece of sticky backed
plastic and make your own biodiesel. That is the view of many people about bio fuels
and new technoloigies, however many of these technologies are perfectly sound and
people mock them because they don?t understand.
No seriously, biodiesel is a fuel made from waste or new vegetable oil, of which there
is literally tons of the stuff being dumped in landfill sites up and down the country!
This otherwise waste is easily collected from chip shops and restaurants and without
too much hassle processed to make biodiesel that can be used to run any diesel
engine. Biodiesel, far from being an inferior homemade product, is better for your
engine than the usual crappy fossil-based fuel that is helping to screw up the
environment and people?s health. Biodiesel can be made in your own backyard with
little start up cost involved and works out at about 30 pence per litre.
A BRIEF HISTORY OF DIESEL.
Let?s first rewind and go back to the beginning of the 1900s where Dr Rudolf Diesel
has just invented the diesel engine and is displaying it at the Paris exhibition. Sat right
there is the mother of all diesel engines happily chugging away running on peanut oil!
Rudolf had designed the Diesel engine to be run a variety of fuels and during his Paris
speech said, "The diesel engine can be fed with vegetable oils and will help
considerably in the development of the agriculture of the countries which use it."
Sounds good for developing countries but not so good for the petroleum industry.
A few years later and Rudolf Diesel?s body is found drifting face down in the English
Channel. After holding secret talks with the UK navy about fitting diesel engines into
their submarine fleet Rudolf Diesel was killed by the French to stop his diesel
technology being fitted into submarines over the world, nothing new there then! After
Diesel?s death the petroleum industry capitalised on the diesel engine by naming one
of their dirty by-products of petroleum distillation ?diesel fuel?. That?s how dirty
diesel fuel has come to be the fuel for diesel engines.
In reality the only reason that we use diesel fuel in our cars is because it?s what is
available and it?s what we have always used. A diesel engine is designed to run on
?HEAVY FUEL OIL? Check your log book and it will say this next to fuel type, not
diesel. However diesel engines have been designed around fossil fuels, but by the
nature of design they can burn a variety of fuels.
Fast-forward to the beginning of a brave new millennium, one where oil is running
out, the climate is ruined and Biodiesel can save the world, well no, but it can do its
bit!, the same as all of us can. Fossil fuels and oils are now running out and it is our
chance to find environmentally sound alternatives. All each of us have to do is to try
and be carbon neutral and use the earth resources sensibly. Unfortunately this has not
been the case and we have a lot to catch up on in a short space of time.

A few facts on biodiesel
Biodiesel is biodegradable and non-toxic. 100% biodiesel is as biodegradable as sugar
and less toxic than table salt. It biodegrades up-to four times faster than petroleum
diesel fuel with up-to 98% biodegradation in three weeks. However, contrary to a
popular misconception, it stores indefinitely in completely full, cool, dark containers.
Compared to fossil fuel diesel, biodiesel has the following emissions characteristics:
• 100% reduction of net carbon dioxide
• 100% reduction of sulphur dioxide Unknw Bio fuel contains NO SUPLHUR
• 40-60% reduction of soot emissions
• 10-50% reduction of carbon monoxide
• a reduction of all polycyclic aromatic hydrocarbons (PAHs) and specifically
the reduction of the following carcinogenic PAHs:
• phenanthren by 97%
• benxofloroanthen by 56%
• benz-a-pyrene by 71%
• aldehydes and aromatic compounds by 13%.
• The four above form the acrid smoke form a diesel engine which you can
smell. They also cause cancer by mutating the cells within our body and also
affect all other animals and plant life.
• 5-10% reduction of nitrous oxide depending on age and tuning of vehicle- this
is small because engines now by design produce low NOX.
For every one ton of fossil fuel burnt, 3 tons of CO2 is released into the atmosphere,
biodiesel only releases the CO2 that it has taken in while the plants it is made from
were growing, therefore there is no negative impact on the carbon cycle and your
vehicle can be considered as carbon neutral with respect to fuel.

A Guide to Making Recycled Bio Diesel Fuel at Home.
We can all produce home made wines or beers in the
privacy of our own home and also you can produce your own
Diesel fuel that will dramatically cut the fuel costs that you
are paying now.
?Diesel? engine is only a term of reference, this type of
engine burns ?Heavy Fuel Oil? which diesel and other bio
fuels are.
The burning of alternative fuel oil is not secret and many
people have been doing so for many years, but over the past
couple of years or so it has been given much more publicity.
Your investment in the technical knowledge to refine your
own fuel will be paid back many times over and the savings
you make will depend on how much fuel oil you produce.
It makes sound economic and environmental sense and will
have a major positive impact on your pocket.

CUSTOMS & EXCISE DETAILS.
Customs and excise hate the fact that people have realised
that it is possible to run vehicles on alternative fuels. They
see it as a way of cheating them and the chancellor out of
revenues. So be very careful who you discuss this with or
read and understand the following details on taxation and
legal issues.
It is not illegal to vegetable oil as a fuel in the United
Kingdom, contrary to popular belief, However it is illegal to
use ANY fuel for road going vehicles without paying the
appropriate duty on it.
In order to pay duty on vegetable oil you must do the
following.
1) Register with customs and excise.
2) Keep all receipts of purchase.
3) Fill in a monthly tax return.
Obtain notice 179E and form EX103 from HM customs and
excise. Fill in the EX103 declaring the purpose of your
business as a ?PRIVATE INDIVIDUAL USING VEGETABLE
OIL AS A MOTOR VEHICLE FUEL? and stating in the
description as ?Fuel containers marked SVO in garage.
Attach an explanatory letter stating that the oil is (diesel
quality liquid fuel produced from bio mass or waste
cooking oil. The ester content of which is not less than
96.5% by weight and the sulphur content of which does
not exceed 0.005% by weight).
Also explain that your feedstock is commercial cooking oil
and / or waste cooking oil and give the following details.
• Vegetable oil is produced by bio mass.
• Fatty acids are esters therefore the ester content is
approx 99%
• The sulphur content is 0.002% by weight (Assayed by
German Vegetable oil company ?Elsbett?
9
Give an estimate of your monthly usage; this will generally
be less than 100 litres for individual use. Ensure that you
include all of your personal conatct details so they can
contact you if they require any personal details.
Don?t worry about all the technical details about esters,
sulphur content etc etc. You don?t really need to understand
them because the details I have given are verified as
accurate and accepted by customs and excise as being so.
Send you completed form EX103 to
HMCE
Mineral Oils Relief Centre
Dobson House
Gosforth
Newcastle Unknw on Unknw Tyne
NE3 3PF.
Every month you will receive a form HO930, filling it out is
not difficult and is detailed in the 179E leaflet.
At the bottom of the list of duty type make the blank row
read ?ORR 33589 Biodiesel? followed by the quantity in
litres and the duty payable. At present the duty payapble is
27.1 pence per litre.
Sign and date the declaration and send a cheque to
?The commissioners of customs and excise? The address
of your local office will be in your phones book.
You must keep all receipts by law for a minimum period of 6
years.

Warranties etc.
Not all engines are suitable for burning home made fuels
and newer cars may have warranties invalidated if you use
these fuels. If you have any doubts then you should contact
your supplier. I take no responsibility for and damage done
or broken warranties and stress that you must do a little
homework first. I have included some websites etc to help
you with this in the appendix.
It must be noted that some vehicles especially those with
certain types of Lucas pump have experienced problems and
I have included references for advice on individual models.
I have been running a Mitsubishi Pajero 2.5TDI for nearly
five years and have covered 40,000 miles with no problems.
However I am very fastidious with the maintenance of my
vehicle. This will help not only with alternative fuels but with
your vehicle in general.
Health and Safety Considerations
If you use any vegetable oil to fry any food it should never
be used until it is dark brown in colour. It then becomes
potentially carcinogenic (Cancer Causing) and as a fuel it will
become too thick and have a to sticky consistency. This will
make burn poorly and do severe damage to your injectors
etc. Also all used engine oils are carcinogenic so I would
always recommend suitable protection when handling spent
engine oils.
11
Dilution.
Personally I don?t use neat cooking oil but dilute it with
regular diesel oil to get a consistent product. During the
winter months I use a 50% to 50% mix. This is because the
bio fuel will tend to thicken in cold weather whereas diesel
has additives to maintain a constant viscosity. During warmer
weather I use 75% vegetable oil and only use the diesel as a
stabilizer. Some people will quote differing figures but I would
recommend starting of at 10% and increasing the mix and
observing vehicle performance.
Now Let?s Make Some Fuel.
When using second hand oil always start by passing it through
a very fine sieve to remove the larger particles of food matter etc.
Once this is done the oil must be boiled, i.e. taken to the
temperature required to cook chips. This is done mainly to remove
the water that cooking food has left in the oil as an emulsion.
This should be ideally done with a thermostatic heater such as in a
deep fat fryer. If you do use a pan on the stove top then NEVER
EVER turn your back on the pan or allow it to become so hot that
blue smoke comes off it. This could result in a major fire and high
temperature flashover.
The oil must now be cooled back to room temperature and will
generally take at least an hour. Personally I tend to cook all of my
fuel one night and prepare it the next day.
You now need to fully filter your oil. For this I recommend using
coffee filter papers in a funnel. These are cheap and surprisingly
hard wearing. If your oil has relatively few particulates in it the
paper should easily filter 10 gallons of fuel. To ensure that fuel is
clean I tend to filter my oil twice and also use a good fuel filter on
my car which I clean once a month.
The clean oil can now be decanted into storage bottles, I use
10 litre screw cap bottles and add your additive which is plain
simple white spirit.
12
To produce 10 litres of fuel, place 0.5 litres of white spirit in
the container and add 9.5L of oil. Make sure that this is well mixed
together and there is no separation of the two liquids.
The mixture must now be stored for around two weeks to
allow the chemical change to take place. The white spirit will lower
the flashpoint and also lower the viscosity slightly. After two weeks
you can now add it to your fuel tank and you will notice that it even
pours and flows just like diesel.
Now you can start to save money, I reckon this has saved me
around £3000 pounds in total for very little work.
I recommend the use of diesel additives to protect your engine,
this is equally applicable if you are using bio fuel or regular diesel.
Always remember the better care you take of your engine, the
better care it will take of you.
13
New Oil.
If you decide to purchase brand new clean oil then this can be
poured straight into your tank without the above procedure,
however when I am using new oil I still tend to add around 0.2L of
white spirit to every 10L of oil to improve the performance slightly.
Rapeseed oil is generally considered to be the best oil but any will
do just as well.
Glycerine.
Vegetable oils contain glycerine (Glycerols) which do not like
cold temperatures and commercially available Bio Diesel contains
chemicals that remove the glycerine. I have included the method to
do this, but it involves quite complex chemical processes and is
only really suitable for the more experienced eco warrior. However
once you get the hang of the basic process you may want to try
and do the complete chemical process.
Purchase of oil
If you are buying new oil then it may be significantly cheaper for
you to purchase it in bulk from a wholesalers, even places like
makro can sell it for around 35p per litre.
If you are using second hand oil then I may be worth a run
around your local chip shops. Don?t forget that they have to PAY to
get rid of old oil and will only be too glad to give it to you. There are
also several sellers on ebay that will sell you 1000L at a time in a
lube cube, The problem with this is that you have to pick it up and
store it. (1000L is 4 Oil Barrels). This would however be suitable
for heavy users or industrial users).

How to improve the efficiency of your car.
Poor maintenance is one of the major factors for poor mpg of your
vehicle and the quality of the maintenance that you carry out will
reflect directly in your cars performance and reliability.
Tyres are one of the most important factors in the efficiency of
your vehicle and also the safety of you and your vehicle. They are
the only part of the vehicle that is in contact with the road. Ensure
that the tyre pressure is correct for your driving conditions and try
and stay towards the top of your tyre pressure range without ever
going over it. 5 Pounds pressure under the recommended
pressure can result in the loss of 10-15% of your cars efficiency. If
you have a four wheel drive this can be as much as 25%.
Driving speed is another critical but overlooked factor. Most car
engines are set up to be at their most efficient at around 56Mph
and driving at this maximum speed will give the best MPG. If you
drive at 80MPH you will use around 20-30% more fuel than driving
at 56MPH. That?s why haulage companies love the fact that lorries
can only travel at 56Mph. It saves them a fortune.
Again vehicle maintenance, regular oil and filter changes will pay
dividends. If your air filter is partially blocked you can send up to
15% of your fuel out of your exhaust unburnt. This will not only
reduce your efficiency but it will also damage your engine and
exhaust system. Your fuel and oil filters must also be changed on
a regular basis to ensure they are taking all of the debris away
from your engine. The debris in your engine not only creates heavy
wear but also increases engine friction and fuel usage.
15
One little trick that I have found to improve the efficiency of my
diesel engine is the use of ?Pure Mineral Oil? as an additive. This
can be purchased from most pharmacies. It is baby oil but without
the perfume added. Also women use it as a laxative. Initially I
started using it as a fuel additive to help lubricate the top end of
the engine. I add 1x 500ml bottle with every 50 Litres of fuel I put
in the tank. Don?t forget, the top end of a diesel engine is lubricated
by the fuel that you use so the better the lubrication properties of
the fuel the less friction the top end of the engine will have.
I also use this oil as an additive to my engine oil to reduce the
coefficient of friction slightly. I add it at a rate of 8 Fluid Oz per
gallon of engine oil and find it does help with efficient running.
However I do change the oil on my car engine every 3000 miles
because diesel oil becomes very acidic and will do damage to the
engine if it is not changed on a regular basis

How to build a single tank biodiesel processor - The titration method
Equipment required
• 45 gallon drum.
• 1/2 or 3/4 Hp electric motor.
• Two pulleys which produce 250 rpm and a max of 750 rpm at mixer blade.
• A belt for the above.
• 12 inch rolled steel rod.
• Two steel shelf brackets (for the blade).
• 1 1/2 inch (38mm) brass ball valve.
• A hinge and a spring to act as a belt tensioned.
• 2000-watt electric water heater element.
• A water heater thermostat.
• 1 1/2 diameter piece of steel pipe * 3-5 inches long with male threads on one
end.
• Assorted tat: angle iron, wood, screws etc.
Assembly
1. Cut a large opening (about half the top) in the top of the steel drum.
2. Drill 11/2-inch hole in the bottom of the drum.
3. Weld the 1 1/2-diameter pipe in the hole at the bottom of the drum.
4. Attach the 1 1/2-inch brass ball valve to the pipe. This is the drain valve.
5. Drill a hole in the side of the drum at the bottom, same size as the heater
element.
6. Fit the heater element making sure it is not touching the side of the drum.
7. Wire up the heater element.
Chemical mixer
1. Attach one pulley to the rolled steel rod.
2. Attach the other pulley to the spindle of the electric motor.
3. Weld the propeller to the other end of the rolled steel rod (shelf brackets).
4. Attach the rod, pulley and propeller assembly to one side of the hinge.
5. Weld a piece of angle iron across the top of the drum.
6. Weld the unattached side of the hinge to the angle iron so the propeller and
rod assembly sits in the middle of the drum. The hinge should swing the
propeller and rod back and forth.
7. Mount the electric motor on the side of the drum.
8. Fit the belt to the pulleys and tighten by wedging a block of wood into the
hinge.
You also need to fashion a simple wooden measuring stick with 10 litre increments.
17
Other bits and bobs
A hydrometer is a good piece of kit to have to measure the specific gravity of the
biodiesel. The specific gravity of biodiesel should be between 0.860 and 0.900,
usually 0.880. The specific gravity of vegetable oil is 0.920 therefore the specific
gravity of biodiesel should be lower than the vegetable oil used to make the biodiesel.
How to make biodiesel
Every time you make a new batch of biodiesel using old vegetable oil you have to
find out the amount of reactants required to get the correct reaction, this process is
know as titration. In addition to the above equipment you will also need the following
equipment:
Petri dish
20 ml beaker
1500 ml beaker
500 ml beaker
Isopropyl alcohol
A graduated eye dropper
Litmus paper
Blender with a glass bowl.
Methanol
Used cooking oil
Sodium Hydroxide
18
Titration
Step 1 Titration: to determine the quantity of catalyst required
1. Measure 1 gram of Sodium Hydroxide onto a petri dish
2. Measure 1 Lt. of distilled water into a 1500 ml beaker.
3. Pour the 1 gram of Sodium Hydroxide into the 1 Lt. of distilled water
4. Label ?do not drink Sodium Hydroxide?
5. Measure 10 ml of isopropyl alcohol into a 20ml beaker
6. Dissolve 1ml of used vegetable oil into the isopropyl alcohol.
7. Label oil/alcohol.
8. Use the graduated eye dropper to drop 1 millilitre of Sodium
Hydroxide /water solution into the oil/alcohol solution
9. After 1 millilitre of Sodium Hydroxide /water solution is added check
the pH
10. Repeat steps 8&9 until the oil/alcohol reaches a pH of between 8&9.
The pH increase will usually occur suddenly. Usually no more than 3
millilitres of Sodium Hydroxide /water solution will need to be added.
11. Use the following equation: · the number of millilitres of the Sodium
Hydroxide/water solution dropped into the oil/alcohol mixture = x ·
(x+3.5)=N
· N= the number of grams of Sodium Hydroxide required to neutralise and
react 1 Litre of used vegetable oil.
· N will be between 4.5-6.5, but it can be higher if the oil has been used for a
long time.
19
Step 2. Measure the reactants
Measure the reactants in separate containers
1 Litre of filtered used oil into a 1500ml beaker
200 ml of methanol into a 500 ml beaker
N grams of Sodium Hydroxide onto a petri dish
Step 3. Dissolve the Sodium Hydroxide into the Methanol
The third step is to combine the methanol with the Sodium Hydroxide to create
sodium methoxide, an extremely strong base. Once the Sodium Hydroxide has been
dissolved in the methanol, the sodium methoxide must be mixed with the vegetable
oil straight away.
· Carefully pour the methanol into the blender, any spills must be cleaned
immediately with a water and vinegar solution.
· Carefully pour the Sodium Hydroxide into the blender
· Replace the lid of the blender and blend on the lowest setting for 30 seconds,
until the Sodium Hydroxide has dissolved. Sodium methoxide has been
produced and caution must be exercised
Step 4. Mix the reactants
· Remove the lid of the blender keeping your face well away from the top of
the blender
· carefully pour the vegetable oil into the blender
· Place the lid on the blender and blend on a medium/high setting for 15
minutes. If the bowl or the blender motor get over hot switch off the blender
and leave until cooled down sufficiently to continue again.
20
Step 5. Allow the glycerine to settle
Settling takes about 8 hours but since 75% of the separation occurs within the first
hour after the reaction immediate separation will be visible. Within 8 hours the
glycerine will have fallen to the bottom leaving a layer on top, this is methyl esters, or
more commonly referred to as biodiesel
Step 6. Separation
After blending the contents can either be transferred into a 1500ml container with a
stopcock or left in the blender for at least 8 hours.
Step 7. Clean up
Store the leftover used vegetable oil in a dry cool place
Clean all the equipment so it is ready to use again
Expose the glycerine to air and sunlight for 1 week and then use as soap.
Pour the biodiesel into your fuel tank
So there you have it, fuel from vegetable oil. Of course this is only one method of
making biodiesel, there are many recipes for making biodiesel just take a look through
the web sites at the end of this article. Don?t be fooled into thinking that biodiesel is
anything but a serious contender in the alternative fuels market, throughout the world
there are commercial processors being built to supply a rapidly emerging market. The
UK government however, has chosen to ignore biodiesel, this is their mistake and
something we can capitalise on. Let?s start making biodiesel and get production down
to the local small scale level with co-operatives and individuals supplying all our
needs while taking power away from the mega-corporations.

Again to point out. This is not nessesarily my oppinion, but something that I thought others might find usful.

BIO FUELS

I READ WITH INTEREST THAT WILLIE NELSON WAS IN ON THIS DEBATE, GOOD FOR HIM.

I RECENTLY ASKED A CHIPPY IN READING FOR THEIR OLD OIL AND WAS MOANED AT FOR ASKING. " IT IS YOU BUGGERS THAT ARE FORCING THE COST UP SO HIGH, NO!! BECAUSE WE NEVER CHANGE OUR OIL WE JUST TOP IT UP" Nice!!!

Bio fuels, diesel, LPG & petrol will all cost the same in the long run regardless of their benifits to the environment. One benifit gained often causes another to be lost and it seems that the Government wins every time and disregards our efforts to become green in its greed for tax. A door is opened and they tax it so it either is just as expensive or in some cases dearer.

It also means the price of chips will rise according to the frier in Reading.

A question that has been whirring around my brain is this: The cost of a barrel of crude in US $ is at a all time high yet the cost of a US $ compared to the £ and other currencies is at a record low, not the lowest it has ever been but certainly it's lowest for a couple of decades or more. So our import cost of oil should be lower than they would have been if the US$ was at a high. If so, why are we paying so much, our £ sterling buys more oil based on the US$, probably 70% more than it did in the 80's when the $ to £ was around 1.28. Yes the cost of crude was very low then but the argument is that a strong £ buys more when the US$ is weak.

Obviously the UK tax is a huge part of the equation and the Goverment welcome increases in crude prices as they get more Tax to waste but no one seems to reflect the fact that Sterling is buying more in US Dollar goods. I heard yesterday that the travel business to Europe has slumped as people are going to the US as it is so cheap because of the strong £ to $ ratio, so why is this strength ignored on fuels?

Oil prices

Read in the Daily Mail that some states in the US are considering cutting fuel taxation, in opposition to the the US Goverment, as the State Goveners claim the people need help in this time of rising prices . And their fuel is still about half the price ours is. Any one care to ring the Chancellor and ask if he would like to consider this move !!!!!!!!!!!!!!.

Diesel @ Thornbury, Bristol £1.20
Diesel @ Yate, Bristol £1.22
Supermarket brand Rapeseed Oil £0.87
Pura Rapeseed Oil £1.07

My mole in the supermarket tells me Rapeseed Oil sales took a sharp decline when the price of 'Pura' was increased,but a noticable climb in sales of their own brand oil in the last few days due the the rising diesel prices. It was suggested that you pay cash for Veg Oil, and do not use your points card for these purchases, wonder why ?????? Who is monitoring !!!! these sales !!!! apart from the retailers.

Reading the above article, I notice that a considerable amount of heating of the oil is required - that also needs to be factored into any costs.

Misinformation

Unfortunately this is typical of the pure unadulterated crap published on the internet, in addition, advocating this type of refining is extremely dangerous. This is why i agreed to write the article on bio-diesel, stating only the facts.
This type of article will have serious repercussions the first time an explosion occurs, and it is reported, and all bio-fuel users will suffer if they refine their own with the correct equipment. Legislation, usually the knee jerk reaction type, typical of this Government will be introduced to combat it, this will most likely take the form of hitting many individuals directly in the pocket.
