my old 94 302 4x4 auto i could get 400km to a tank 70litres i think that worked out aroun 18mg then it dropped to about 300 km to a tank but i had around 400000km on it
my 97 with 4.11 gears super crew 4x4auto (c6?)or aod) no electric button) i can get around 280 to a tank 70litres. if im towing i can get aroun 180 to a tank if i,m lucky.
now my 90 crewcab 4x4 with a 7.3 and a 5 speed with 3.73 gears my best was 575 km on 70 litres all hwy. and if i towed i would get around 360 km on . i miss that truck.
call me a sinner but i know have an 03 dodge diesel 4x4 quad cab that i get 880 km to 140 litres empty, or towing i will get about 700 km. about the same as my 1990 so you tell me where the 13 years of technology went to improve the mileage?
