I would not drive 30 miles to get it - in Ontario 91 is available at select gas stations as Ethanol free (e.g. Shell, Costco) and I have a station less than a mile from my house. It definitely gives better mileage and is the same price as the one with ethanol in it.

We don't have an 87 version though so have to use the corn syrup.

I see it advertised around here but I heard it really isn't ethanol free in some cases. They just tape a note to their gas pump trying to get more money for regular premium.

I have ethanol free (91 octane) right up the street from the house. The 62' gets it and nothing else. I don't think I have been far enough away from home with it to have to worry about finding it elsewhere.



Use BP 93 in the GS. I may try the corn free in the GS though I doubt I notice any dif.

Well, if you feel this is true, then turn their behinds in.

Ethanol free gas is probably of little benefit to C6 Corvettes (or C5s or C7s). I haven't even mentioned it to the owner of the C6 I take care of.

If you have a vehicle that is susceptible to damage from ethanol or that just won't run on ethanol blends, you don't have much choice. You have to seek out the truly ethanol free gasoline.

I've had to replace the CIS Fuel Distributor (the central portion of the Bosch mechanical fuel injection system) on our 1989 Mercedes Benz 560-SEL because of ethanol damage. Parts for that system are getting very hard to find, and it's even harder to find someone knowledgeable enough to do the work and get the thing properly tuned and set up after a rebuild. Now she gets ethanol free every time we fill her up.

I'm lucky enough that we have three stations in the area that sell ethanol free (plus a few that are listed on pure-gas.org that claim to sell ethanol free, but their gas actually contains some ethanol). The nearest truly ethanol free gas is 87 octane, and there's 91 and 93 octane available at slightly greater distances (still within 15 miles of home, and within a few miles of common destinations for us). I try to keep the blend in the 560 at 90 octane or higher. I do occasionally top up with 87, but only if there's enough 93 in the tank to keep the weighted average over 90.

I also run ethanol free in the garden tractors and in the outboard on the boat.

Where I live the only place one can find non-ethanol gas is at the marinas.

Easy to find 93 octane Top Tier gas though.

I have 4 or 5 stations within 15 miles of my house that sell 91 octane ethanol free. I don't seek it out, but I will stop at one of those stations if it is close when I need to fill up. Otherwise, I use 93 octane ethanol blend from the one station close to my house that sells it for the same price as the others that sell 91.

I do use nothing but 91 ethanol free in all my small engines. I saw what damage ethanol does long term recently when I had to rebuild the carburetor on my 4 wheeler, in spite of always using Stabil in the gas for all of my small engines.

I guess maybe I should revise my statement about C6(+/-1) Corvettes and ethanol free gas slightly.

For a daily driver, I wouldn't bother.

If I was going to park it in the garage for the winter, I'd run it as low as possible and tank up with ethanol free (+ Sta Bil) for the winter storage. I'd try to find 91+ ethanol free, but I'd park it with 87 ethanol free rather than any ethanol blend premium. Just remember if you have low octane in there in the spring, drive gently until you use it up and fill with premium.

DavidandJoansVette

I use ethanol free 93 octane from Citgo in everything I own with an engine. The 77 Vette for obvious reasons. The lawn tractor does not backfire and the 15 and 16 Jeeps run quieter. I pay through the nose for it.

I use ethanal free in my 'vette and 328i, both take 91+ and it is available at the station near my place. Close to a wash in price increase vs. mileage increase. If it wasn't convenient I would not go out of my way, newer cars are OK with ethanal. Exception being winter storage as C6 Racer X mentioned , then a clear advantage for corn free gas.
