lol...anyone that has any knowledge of cars in the least will tell you correct tire pressure, a fresh air filter, plugs, and oil change will help out fuel economy.
This dude never specified if his increase was driving hwy miles or city. I say BS. He probably took starting mileage in city driving and the ending in hwy mileage -which actually is just about our cars averages (19/29 per mfg specs.) I can get 24-26 city and 32 hwy with my 03 TLS..without acetone.
