Italian tuneup

From Wikipedia, the free encyclopedia

An Italian tune up usually refers to a process whereby the driver of a motor vehicle runs the engine at a very high rate in order to eject carbon buildup from the combustion chambers. It is often accompanied by an addition of fuel system cleaner to the fuel tank.

[edit] History

The origin of the Italian tuneup comes from the 1950's and 1960's era of Italian cars, which purportedly reacted well to a 'tuneup' of this kind when the engine had built up enough carbon inside to affect performance.
