Thank You Drummer World!

My cars all say premium fuel required but I am the one paying for it so they get the cheap stuff and I don’t see any difference in like 15 years

I have always heard that unless you are driving a race engine, it doesn't matter...87-89-92 are all so close that it doesn't matter in the long run

I think I sort of believe that 92 helps clean out fuel injectors better than 87, but maybe that is it

The higher the octane rating, the more stable the fuel (less chance of pre-combustion).
