FYI :oracle said:If the engine detects pinging it will advance the timing so it drops the power.
Yes, you still can, but after you change it you find out that everything is messed up because you reset the computer that controls everything. (PS. Don't blame the computer, i gain my daily bread with it )GARYD said:John, I can still change my batterys........after removing dozens of brackets, wires and hoses......... and the passenger seat. LOL

To reduce pinging, you need to retard the timing - NOT advance it.
And yes, this will reduce power.
(spoken from a person who used to own cars that you had control over the timing by rotating the "distributor" - a what, you ask - never mind, ask your father or grandfather !)
My 2020 terrain 1.5 SLE 9 speed runs better on premium fuel. Also MPG up to 33 34 now.My C5 Corvette will run all day at any speed on 87 octane ( even though the owners manual states 90+)due to the computer controlled engine. Our SUV engines are also computer controlled, designed to run on 87 octane so anything higher is simply wasting money.
