Fuel
So I have no gas stations near me that sell high octane, and out here in AZ our best fuel is 91 octane. What’s everyone doing for these older cars that need leaded high octane fuel? It’s an original LS6 with 11:25 compression. I don’t race it or drive it hard, but when I do jump on it every once in a while I can hear a little knock. Currently use lead additive and Torco, but not sold on that solution.
