octane levels
here in lubbock it is very hard to find 91-92 octane, my gas mileage has dropped from 19.5 in town to 16.8 since having to use 90 octane, any correlation between the 2 or s it just me. I don't drive sweetthang only about 3 days a week and I driver her like a grandpa, but this is pretty dramatic drop in gas milage. any clues. do I need to reset fuel trim to live w/ sh^%$$ty gas??
