My Camaro has had piston slap when cold since it was new. Sometimes it can be so loud that people think I have a rod knocking. It goes away after the car warms up. 213k miles so far and it runs great.
I had a 1983 Celica with a 2.2 and it had a similar ticking sound all the time, not just when cold. It ran just fine with a ton of miles on it.

Putting 93 octane into an engine that only requires 87 does absolutely nothing except waste money.
