Fuel Saving Tips
Engines that aren't exercised regularly will develop carbon and sludge. No amount of snake-oil from a can, bottle or dealer will get rid of it. The way to prevent it is start your car, drive around 10 minutes to get it up to temp, and then give it a few hard goes. A few runs of 30 to 50 at wide open throttle. Be sensible, do it on the open road. Or are you willing to sacrifice your engine's longevity to save a dime a mile? Think on it. Sludge and carbon are *not* natural, they come from pussyfooting the engine.
