1991 td42 (non turboed) LWB 33" muds
Boy I think I have a problem, filled the tank , zeroed the trip meter drove around till we got to half a tank and then filled it up again. 43lt and only 2.3km!!!!! By my math that works out at 1886ltrs per 100km
Then figured it wasnt worth fixing the odo and trip meterso I did the same excerise with the gps and got 12.6 lt per 100km and felt better about life
