Are there any truly effective products out there that can clean the carbon out of the combustion chamber that you only need to add to your gas tank? I've added two bottles of Redline Si-1 to my Corvette in the past month but yet I still have some pinging with 91 octane gas. It goes away with 94, but our 94 up here has 10% ethanol in it (while Shell 91 has none) so I lose 2 MPG, plus it costs 3-4 cents more per liter than 91 also. Since the Vette is my daily driver, those extra costs add up.
I know that a lot of people have seen great results at removing carbon buildup by sucking Seafoam into the engine or misting in some water, but I don't want to do that for two reasons (one is that I just changed my oil to Ultra and don't want to have to change it again right away, and two is that I'm afraid to hydrolock the engine if I do it wrong)
So has anyone here found an effective carbon cleaner that you put in the tank? (even if it takes a few tankfuls worth to do it I don't mind) I believe Canadian Tire just started selling Gumout Regane up here, what do you guys think about this stuff?
