I get crap mileage, making me think its running in limp mode or something. Like 10 mpg around town and 17 highway. Granted the 10 mpg is usually trips less than 5 miles, but does suck having to refill every 150 miles. 87 only, fuel gets boated in up here and is almost always over 4 bucks a gallon unless you go to costco or the company that barges it in.
