No difficult problems, just difficult people
My friend in the petro-chemical/industrial lubricants business says otherwise. According to him, higher grades do get better packages of detergents/additives/etc. He told me this years ago when I remarked I had tired of different gas cans for everything from lawn mowers to snow blowers to cars to motorcycles, and had switched to premium for everything. He said that was a good thing, as now my outdoor power equipment was going to have a cleaner and better maintained fuel system, even if the engine didn't require, nor gained any advantage from, using premium. I've since stopped doing that due to the vast amounts of lawn I now mow, but I still run a tank through the outdoor stuff from time to time.Firefight911 said:Fuel octane ratings have absolutely zero impact on fuel quality so just because you put regular in it means nothing. There are no different detergents from one grade to the other. It is an anti-knock/octane difference only.
As far as fuel grades and fuel filters: grades don't matter, contaminants and debris does.
