Lately, I've been contemplating the process of plasma coating the internal components of an engine for increased fuel efficiency.
For those of you who are not familar with the process, it involves a rotating plasma torch used to deposit a ceramic coating onto the internal components of an engine, which in turn reduces heat & friction up to 30%. The by-product being a more durable engine with increased fuel effiencey. This process is not new. It's been used on jet engines, race cars and yes even your garden variety automobile.

At this point, I'd like to know if there are more people who are more familiar with the process, whereas I'd be interested to know if it's worth the time and money to invest. My theory is that one you may be able to take a fuel efficient engine such as a 3-cylinder Geo Metro, or 4-cylinder CRX-HF, while improving the fuel economy evermore so. The question is how much of an estimated increase should be expected in Miles per Gallon.
Thank You.
