I accidentally put supreme in the car instead of regular? Any warnings of what may happen?

Nope, Its just a higher grade unleaded fuel, If you put diesel in you would have a problem though. Some cars come from the factory running on 93oct (for instance sports cars)

Oh no! just kidding. You may get slightly better mileage. Actually, the higher octane in the premium fuel will clean your fuel lines a little. It shouldn't hurt your car at all. If your manual recommends that you use regular, you should stick with that. Every now and then it's a good idea to use premium to clean out your fuel lines but don't use it always. If your car is designed to use regular, it will not benefit from higher octane fuel. Sometimes you need higher octane fuel if you have done any modifications to your engine or computer. All in all, a few gallons of premium won't kill your car. Don't worry

you pay more. Asolutely nothing happens. It will not run better or worse because your car only takes regular. Higher octane gas only has a higher stress limit then regular. Because you do not have a high performance engine. There is not much stress (high temperature and pressure) being put on the fuel hence there is no need to use premium. Here this is a previous answer of mine. It's a little in depth but it explains the physics of how gas and the modern engine work together.

You _should_ use whatever the owner's manual recommends. If your car is experiencing engine knock, then you should go up a grade in octane.
Octane is a measure of the fuel's ability to resist pre-detonation (or engine knock).
Higher octane gasoline doesn't mean that it is necessarily cleaner or better. "Premium" is a mis-nomer. All gasoline sold in the US must meet certain federal EPA clean-burning guidelines. However, some individual brands _may_ decide to only put the extra cleaners in their higher-octane fuel (as I've heard of some brands advertising low-sulfur gasoline as only in their Premium line (sulfur reduces the cataylst's functions over time)).
A higher octane gasoline actually has lower BTUs (energy content) than a lower octane gasoline, so the only way that you'd see better fuel economy by going up in octane is if you were previously using lower than recommended octane in your car... You may not notice any difference, but likely you'll see slightly worse fuel economy.
(In my particular car, a Toyota Prius, using higher than recommended octane fuel is known to cause check engine lights with engine misfire codes, besides the expected lower fuel economy. But that could be because of the Atkinson/Miller cycle engine, and not the usual Otto cycle engine found on most vehicles.)
If your car's owner's manual says that you need to use a higher than regular octane, you should follow that. (Pre-detonition over time can cause harm to the engine.) However, every once and a while you could use lower than the premium fuel, and get away with it...
The big no-no is putting diesel fuel into a car that requires gasoline.
E85 in a car that isn't a flex-fuel vehicle also could cause problems over time, as well.
But higher than required octane in a gasoline car? no real long term effects other than less money in your wallet, and perhaps more fuel burned than would otherwise be required.

Some cars are not meant to run on gasoline that is so rich so you might get a little skipping but probably nothing will happen.

your car might run better, it might not. that's why it's supreme. it certainly won't hurt your car. it's actually supposed to be better for your car, but that's up to debate.

you paid more for gas than you need to do. Other wise everything will be fine.
