[Jorge1313]

i live in Florida it happen a lot last hurricane a year ago or more. I was out looking for gas to keep gernerators running at 3 am weekly gas would run out by 6 am . Now if a have a 6.2 engine it require premium or you get a kick and ping. I read people say it can damage the engine that knock and ping. Explain what happen to engine how long can you regular only gas option was regular gas . What happen if you use regular will void warrenty.

Short answer: you'll be fine.
Long answer: lower-octane fuels are really only a problem when you have forced induction (i.e. a turbo or something). If you run low octane with FI then you can have detonation, which can be pretty damaging. I have a 6.2 and ran regular in it for the first few months of ownership and was fine. It's not a big deal for these engines.

Keep your tank topped off and don't drive if you don't have to. Alternatively, you could probably get away with E30 Ethanol even though it is not rated for it. While everyone is in line for gasoline during last storm, I pulled right up to the yellow handled pumps, took on E85 and left lickety split!

You can also stock up on REAL gas cans, Jerry cans by Wavian. These will not leak or smell inside your truck and with the original spout, not spill when pouring.

I went by the book it mention premium and only tier 1 gas stations

The engine will definitely explode.

You'll be fine. It will pull some power but nothing will be damaged

All gasoline-powered vehicles sold in the United States must be capable of operating on 89 octane unleaded fuel in order for the engines to be EPA certified. As far as I know, you could run a premium-fuel recommended engine on 89 octane fuel indefinitely without damaging it. You could experience some detonation (knocking) but most modern cars have anti-detonation sensors that would mitigate. You may sacrifice some MPG and/or performance.

Note that the label on your car probably says "Premium Fuel Recommended" versus "Premium Fuel Required."

Second what WillCO said. Modern computer-controlled engines monitor for pre-detonation and alter the timing accordingly. You may suffer some performance loss, but nothing will be damaged. Pre-computer controlled engines are another matter, driving them hard and causing them to knock will damage the engine.
