3) Fill up with 93 octane and ALWAYS use the "jet fuel" octane booster from Walmart

Do these things and you'll get 55-65 mpgs in town no problem

All of the above. Plus I removed my hood and intake, so the air freely flows into the engine. I get 70+ mpg hwy easily.

As for flushing the engine with water... Ask the mustang kid about the performance increase it gave him!
