Does anyone burn 91 octane non ethanol gas or is 93 octane leaded still the best? Any problems with N E gas?

That is what I heard from others. I have put it in my lawn equip. & generator but was hesitant about the vette. Looks like that will not be a problem though.

My mistake, I did mean unleaded 93. But, can it be mixed with NE?

No problems mixing 10% ethanol gas with non-ethanol gas. The car will run fine.

I've been using unleaded 92 octane with 10% ethanol in my supercharged '02 since '05 and have never had a problem. There are a couple stations that advertise premium non-ethanol, but they are out of the way and 12 cents per gallon higher.

I have heard that some stations have no ethanol or lower amounts in their premium gasolines but they don't advertise it. Most all stations that I use that have multiple hoses on a single unit only put one sticker showing the percentage of ethanol on the unit and it's typically near the 87 octane unleaded regular hose.

In a C5, I'd rather run 93 octane E10 than 91 octane non-ethanol. No evidence that E10 is harmful to C5s.

If you have a pre 1980's car, or boat, or lawnmower, then skip the ethanol. If you have a modern fuel injected car, ethanol is not an issue, and in fact offers some performance benefits, especially if you have a F/I or high compression motor.
