Hi Pat,
I've used this product on American cars and it does work. I had a 1989
Mercury 5.0 that badly fouled the #8 plug. I wanted to try to
decarbonize the engine so I decided I would decarbonize and then change
the plugs. I followed the instructions...man does that stuff
stink....then changed the plugs. The plugs, including #8 were completely
free of carbon. I've heard of people using this because of compression
ratios being raised due to carbon buildup and the ensuing pinging.
Combustion Chamber De-Carbonizer - Goodwrench Top Engine Cleaner. Spray
can part# 1052626. Non spray can part# 1050002. About $8 per can.
Good luck,
Jay
> Does anyone have experience with any gas additives that could remove
the carbon or other alternatives (I would like to put off a rebuild for a
few years)?
