my daily commute is 140 miles roundtrip with 95% on the freeway @ 75+mph in the San Francisco Bay Area. That coupled with minimal weekend driving, except for three autcross runs every two weeks I have been averaging 32-34 mpg. runflats at the proper pressure and oil changes at every 5000 miles helps to keep the fuel economy up. If I wait the full 15,000 miles between changes the mpg goes down 2-3 mpg. Oh and 91 octane from Chevron is the only thing "HOPKIRK" ever sees
