Talked about a few times over the years on this forum- this video suggests premium fuel is a waste of money.

Thanks for posting that interesting story Guns.
Most modern cars can perform well and do recommend in the owners manual 87 octane gasoline.
For Super charged vehicles premium fuel is recommended.
What was not mentioned in the story is ethanol based fuels, or premium fuel'* advantage that contains no ethanol.

Considering I live in a rain forest, moisture absorbing ethanol fuels do not appeal to me, so I run 94 octane Chevron.

I can't get ethanol free, and that makes me mad, as well as the PA. It gets pissy with ethanol. I also run 91 because it gets even more pissy on anything less.

They're right though, if there is no added gains, there is no point.

Apparently ethanol fuels start to sour at about 21-30 days according to tests by marine outfitters.
Phase separation (small amounts of water) in these fuels can really make engines run like crap, injectors problems & who knows what else.
I guess a good idea is to get your tank close to empty, and refill every couple of weeks.
I don't think water absorption in the fuel is that much of a problem in summer, but come winter time, if I was running ethanol fuels, an ethanol fuel stabilizer would get added frequently.
I recently came across a product that treats ethanol fuel well.
Starbrite Star Tron may be worth a try, & see if the PA runs any better Randall with it in the fuel.
