GAS
I have a 2013 Chev. Silverado with a 5.3. The users manual says to use TOP TIER gas. What is this? I have been using various brands with no difference in performance. Comments? Thanks, John

Engines don't compensate for the fuel octane per say. It just listens for "pinging" and retards the timing if necessary.
True and in doing so they are compensating for a lower octane and you can never know it other than possibly notice a slight drop in power and mileage.
