[QUOTE="julie2121, post: 2861397, member: 6680"] CARBON CLEANING for more power and save fuel "The Tune-up of the Nineties," is what the literature claimed. It was said to clean enough carbon deposits and other contaminants from an engine to improve fuel economy, ease cold-starting, promote a smoother idle, quicker acceleration, and increase power. All this while lowering exhaust emissions. Pretty strong claims. Strong enough to arouse a good bit of skepticism from one who’s experienced any number of snake oil salesmen over the years. The product is usually some magic elixir which, when added to the gas tank, is supposed to miraculously cure whatever ails an engine. You know, do damn near everything but lower your cholesterol. Baloney. This one, however, wasn’t an additive. Called MotorVac, it was a procedure that sounded pretty logical, and importantly, the results of which could immediately be measured. That got our attention. The fact is that even a one-year old car’s engine has accumulated carbon deposits, gum, varnishes, dirt and other contaminants that build up in the air intake, fuel delivery system, combustion chamber, and exhaust system.
