Piston slap may not be a bad thing when the engine is cold. I used to worry about a bit of knocking in some of my other cars especially the Toyota truck I had (turbo 2.4 litre gas). I was told that some high performance engines should sound a little loose when they are cold since they have internal parts that expand. I also remember something about high performance pistons (hyperetic? Spelling probably wrong) that actually were oval shaped when they were cold and turned round when they warmed up. I don't know if any of that is true.
I put Chevron Supreme (92) octane in my Corvette exclusively and I still have a little piston slap for the first hundred feet or so. I have to go a couple of extra miles out of my way to get Chevron, but It's been a good performer for me. I got my Vette used and the previous owner probably just put 'whatever' into it. I had to replace my gas sending units to the tune of $1300. I wouldn't take a chance with other gas on a regular basis. -
