Keep your tires aired up, and the front-end aligned and a clean air filter and that'll help some too.

And Welcome to CF.

One that gets consistently overlooked is changing your O2 sensor when you change your plugs etc. When they wear out, they can make your milage drop by making it run rich.

Its an addative you can Pour into your Oil or your Gas, and (correct me if im wrong) but it "Burns" up all the build up and sludge in either the Oil System or the Fuel System, depending which you pour it into.
