The new shell nitro blend works better for me than non-ethanol off-brand 93.

BTW there is nothing to fear about ethanol. It burns cleaner and has higher octane. The MPG difference is only 3% less from my extensive testing (OCD and record manual calculation then compare in list) and the increased price of non-ethanol doesn't make up that difference. Top tier brands have better detergents to keep the car running well.

I moved to Oklahoma City where they have the good stuff right out of the tap. I need to change my profile.

Yep !

And we have the lowest octane of 91. I used to routinely use xylene in my 85 Euro M635 to push the octane rating up a few points. But even that got real pricey and hard to find.

Lot of places sell non-ethanol gas; however, not with 93 octane: https://www.pure-gas.org/

All the corn farmer politicians in IL need that kickback money tho...

Costco 93 is my go to. If I'm hitting the track, then Shell V-Power.

Meijer for diesel in the truck; only place near me where I can get non-biodiesel mix.

For us in Ca most we can get at the pump is 91, my GT3 barely gets by with it in the winter, summer time it won’t tolerate it .

As for ethanol fuel I wouldn’t sweat it, 991 is perfectly fine, even a nineties era 993 is ok but if you keep your car in storage for months at a time ethanol free fuel in the tank is highly recommended.

As for 100/101 octane unleaded race fuel sold at gas stations I can almost assure you it has more ethanol in it than the average 93oct pump gas.
