    Seafoam's webpage says you can use up to 50/50 seafoam/gas and not cause a problem.

    Seafoam is not going to knock carbon off the combustion chamber and clog the cat. Oil burning over a period of time can cause cat issues.

    I had a guy put in diesel in his reg gas car. That was a problem!

    Okay thanks I'll just run out the fuel and hope I don't get the triangle of death and it shuts down.
