Default Can you use Premium gas if your car manual says"Regular Only?

The gas stations(the ones open anyway) only have premium gas,but the manual for my car says use regular only.

There are very few gas stations open,and they are running out of premium gas too. Lines are super super long.
My gas light is on.

Would I damage my engine if I use premium this time only?

Yes you can! Higher octane fuel will not damage a vehicle designed for regular. You won't likely gain anything but no damage will be done.

Yes you can, with no problem except the damage to your wallet. If premium isn't recommended or required for your car, there is no advantage to using it. In case you were wondering, you can mix premium and regular when that becomes available.

That is actually how the mid range gasoline mixed in pumps.

I've been driving for 30 years, and more importantly putting gas in the car for that time, and only learned that little tidbit a year ago. It hadn't occurred to me prior to that.

You will likely get slightly worse gas mileage and you will pay more for the gas. Otherwise it makes no difference.

Some people put premium in thinking it will clean out their fuel system, or give them more power or better mileage. If the car is not high compression, thye are just throwing away money. Premium does absolutely nothing for a normal compression engine.

Putting premium gas in a car that takes regular won't harm it.

However, putting regular gas in a car that takes premium can and, over time, will likely harm it.

The only difference between gasoline grades is the additives put into the gasoline, otherwise it is gasoline. You cannot obviously use gasoline in a diesel engine and vice versa but premium gasoline will not harm your engine no matter how long you use it.
