My '16 BRZ limited has the engine chipping as of 3600 miles. I had always filled it up with Shell 93 octane fuel. Particularly in the AM in my commute they get louder on 93. I fill up at the same 1 of 3 gas stations every week.

I filled up on 90 octane ethanol free fuel yesterday at a Mallard station. So far the crickets are nearly non existent on that gas. I am unsure of the performance between them or MPG.

I'm not really noticing difference at all. Is there supposed to be a performance change in between the fuels?
