[QUOTE="RDR2019, post: 1518289, member: 32872"] Your truck will have knock sensors to prevent damage from mistimed detonation, modern fuel injected engines all have this to respond to varying octane levels and elevation changes. Your truck will likely have a table of values it will resort back to while the lower octane fuel is present and it will clean things up pretty quickly once you move back to the correct octane. Modern FIS are pretty slick in that regard. You can always dump in a bottle of octane booster and/or top things off with a higher octane fuel...or if you are really concerned siphon out the gas and refill the tank with premium unleaded fuel.
