Hello all, I'm new here and would like to ask a question. I just picked up an 01 sonoma ext cab, 2.2L auto tans. Truck has 84,000 miles and seems to run good, however I'm only getting 18.4 mpg about 50/50 highway and city. This is the first tank of gas I've ran through it so it may get a little better as my normal driving is more around 75%highway. Is this normal mileage? This truck is replacing a 2000 Nissan Frontier King Cab which got 24.5 mpg consistently. The Nissan did have a 5 speed manual but I wouldn't think an auto. would be this bad. My '97 Blazer 4x4 4 door 4.3 V6 got as good as this thing does. Any thought or comments would be greatly appreciated.
