Default Re: High Octane Fuel

You said "base gasket" then you said "the gasket between the block and the cylinder head". So, which one is it?

How much would that raise the compression, maybe to a whopping 7.5 to 1? High octane doesn't do anything until you are just a little higher than that- say 10 or 10.5 to 1. If you are running the chinese engine @ 10.5:1 I don't think that it will last very long.

What is a "noteable difference"? Compared to what?

Just askin', not arguing.
