In all my small engines and my boat I use ethanol free marine fuel. It costs more but for me it is worth it. When I store my C5 I do my best to run close to empty and fill it with ethanol free fuel. Depending on where I get it the fuel it is sometimes only 90 octane. I believe it is far better than high test ethanol and would use it more often if it didn't cost more. Corn farmer laugh all the way to the bank every time we fill up. To answer your question I never had a problem mixing.

There should be no issues at all. I wish I could run ethanol free. That is what I run in my SUV. However, in my area I can only get ethanol free in 89 octane. With the blower (and the way it is tuned), I really need 93 octane.

Thanks for the response. Buc-ee's down I-45 in Texas City, TX has at least 5 pumps that dispense 93 Octane E0 gasoline that I've been using in all of my small engines. As far as I've seen, all of the larger Buckee's have E0 gas which is a little costly but have you ever had to de-gunk a carb? I'd pay plenty to avoid that task. After Hurricane season, my plan is to put the remaining 20 gallons left over this season in the C5. I didn't expect any problems but never hurts to ask the community.

I always start using no ethanol 93 about Oct.-Nov. in my Vette and Harley, because I don’t want them sitting thru the winter months with ethanol in the tank or lines. Absolutely won’t hurt anything.

I'm with DDaaryl, in my small engines I run non-ethanol gas only. In my Corvettes, I run 93 octane with 10% ethanol and haven't had a single problem. I do run an occasional bottle of Techron and before storage she gets some Sta-bil in her.

Don't understand your post. I've been buying and using gas in both vehicles and small engines since well before either ethanol or MTBE were added, and I have been degunking carbs for an equal period of time. That's why years ago, we all would keep a supply of carb cleaner on hand. Ethanol makes no difference.

No problem with ethanol free gas. It was designed to run on ethanol free gas. It will tolerate up to 10% ethanol, but it isn't optimal. If you store it for the winter, ethanol is not good for the fuel system components. It is corrosive (bad), degrades plastics and rubber (bad), and absorbs water (bad).

Ethanol free gas is the best Choice, ethanol free is not hygroscopic. Ethanol fuel can have potential for phase separation at any ethanol level and it's hydroscopic, additives like Biobor EB is great to use with ethanol fuel and helps with the problems of ethanol fuel. If you are storing your corvette or any other vehicle for a long time I would try to get E0 if possible. If ethanol free is not available I would add Biobor EB to the take of fuel.

No problem with running Ethanol OR No-Ethanol.
However, it is not advised to run them both, mixing gas from time to time. This was advised to me via high performance offshore boat arena; per mechanics that I trust. There is something about the pure gas, and how it reacts with the chemical compounds in the Ethanol gas.

I'm with the others that do't use ethanol blends in any of my small engines or boat. I also quit using it in my C5 at least a month prior to winter storage. The beauty is no Sta-Bil is ever needed, and I honestly cannot remember the last time I needed to clean a carburetor. Our local hardware store does small engine repair, and the mechanic swears that he'd need to find a second source of income of they ever stop adding ethanol to the fuel.

At the very least, ethanol or non-ethanol, make sure you buy gas from brands that meet Top Tier specs for detergents:

And no, it's not a gimmick.

Most of these "prep for winter" additives, etc., are unnecessary with modern gasolines. Certainly I have never needed to use them in any car I have owned for more years than I can remember, and some have sat for long periods during the winter.
