Re: Ernst from Turllock Ca
I'm not trying to be a smart ass.
You said your last motor got so hot it was dieseling (you couldn't turn it off with the kill switch)
Now you have pinging or knocking which is detonation.
Either of these can destroy an engine.
Higher octane gas is more resistant to preignition.
That all. I'm done. Over and out.
