Hi. Got a Fourtrak 2.8lts tdi and it used to make around 200kms/tank. Thought it was too little so decided to get the injectors done as there was black smoke coming off the exhaust. I got an additional 40 kms/tank after that... was just wondering if it is normal for it to swallow this much diesel or if not what could possibly be the cause. Note* The car has been sitting for around 2 years before i got it on the road again(maybe it could be something related). Your help would be greatly appreciated.
