i've changed my driving habits. lol
I saved the most mileage by not going out at 4AM and cruising for "end of the night" discount prostitutes.

I removed the big intake silencer in the passenger front bumper, switched to iridium plugs use 91 octane, performed a fuel system cleaning and then changed the fuel filter along with a K&N air filter. In a 2.2 keeping revs around 2.5k is the best I've found to improve mileage.
using 91 octane in a untuned 2.2 is a waste of money.
