Seafoam or not?

I have run many tanks of 89 octane through mine. It won't ping due to all the sensors and ECM programming.

Unless you're towing or racing, you won't notice if there's any loss of power under normal conditions.

Back to the original question of how to free up potentially gouped up rings.

FYI, I ran 1-1/2 tanks of mid-grade Shell in the Aviator. Idled noticeably rougher and got about 10% less fuel economy. Didn't notice any power drop but I never push it anyway. Back to premium for me.
