With my old tired 2.2L with 200K miles, I get about 375 to a best of 429 per tank...15.9gal tank. I could probably do better....anyone every tried any of the hyper mileage tricks? I've been driving about 60mph on the freeway lately just to see what I can do. I'll have the car loaded up to go from San Diego to San Francisco this weekend, about 300lbs of gear and 2 x 200lbs guys
