My 190 16 valve gets around 17 mpg in the city and about 22 on the highway at about 75/80 mph. Is this normal for the 4 cylinder 16 valve 190? The car also has a big bore throttle body by Bekkers. What are all you fellow 16 valve's getting in terms of gas milesga. The fuel injectors have been replaced, fuel filter is new, recent ignition tune, and tire pressure set to 32 lbs all around. Is this normal?
