The manual for my 90 says that it has a 15.4 gallon tank, and I can believe it. I ONLY drive in around town (city) and I get 180 per tank when I drive "nice." That works out to about 15mpg when I fill up w/ 1/8 tank left. I have brought that number close to 100 when driving more, exuberently.

My average is around like 14.7 mpg on the street. Its been as low as 13.5 but I think those are flukes. This is with my 3.08s too!! Maybe california gas just sucks! I get around 200 miles per tank, but I dont read it by that. Like many of you, I divide the number of miles I put on by the number of gallons put in.

I have 3.73's flows and a k&n and on highway at 65-70 measured 22-23 mpg, i haven't been able to get more than 9.5 gallons of gas into my car though!! i run it down as far as i feel comfortable and still haven't got more that 9 gallons in it, what could it be, i go about 200-205 to a tank then have to stop for gas.
