LA360 Octane

Stock 360 ? 87 octane. Boosting octane doesn't boost horsepower, only keeps it from pre-detonation if the chamber pressure is too high.
Just wasting money if it doesn't ping with lower octane fuel.
I would just make sure the station is pumping Tier 1 rated fuel.
This is fuel that is recommended by the car manufacturers. Most cut rate stations have sub standard rated fuels.
