260-280 miles, 25-28mpg. Driving about 63mph (30mph with as little as possible stops in city) 90% highway according to my gauge which I feel is accurate as all 3 cars I've tested on WA/OR meters are exactly 3mph slower than my gauges. 2003 Jag, 1990 Cressida and the 2005 Aveo hb.
2.69gal, $24.5 for 9 gallons which fills it on Fred Myers auto off detect level, I try to always fill it at the last notch because of how far I have to drive I can't dip lower and it's cheaper at work than near home. Tire pressure 49front 44rear, correct pressure to the temps outside and tire sidewall rating. All season tires. I also try to eliminate making an extra stop for gas by filling only when I need to.
I think a street summer pattern would get even better mileage I also think all the wheel bearings need to be done. Needs the inner fender wells and maybe the GM roof racks removed since I'm not using them. No check engine lights.
I'll do some even more precise calculations soon although I'm always going to use Fred Myers auto off pump feature because self service isn't allowed and it's that much cheaper on the OR side.
