Re: Gas confusion
If possible, use non ethanol, if not use the smallest percentage of ethanol gas, as possible. The insides of carburetors and rubber hoses, do NOT do well when exposed to ethanol...

Re: Gas confusion
Here in Iowa too- I run non-ethanol in all my small engines and in my older vehicles. Usually Kwik Star has it in Premium only and possibly Casey's as well but I haven't been to one lately. I've ran the E-10 without an issue but run that out before storing for any period of time.

Re: Gas confusion
Pretty sure federal mandate is a minimum 10% ethanol nationwide. I haven't seen non-ethanol blend anywhere in the midwest for a long time. As for regular, premium, etc., my stock '70 350 has 120k miles and runs fine on 87 octane. I would avoid E85 and others blends that are more than 10% ethanol. Although those are usually less expensive, you're milage will be lower, and the added alcohol can cause problems.

Re: Gas confusion
It was suggested that I use premium, not for the octane but because it has a lesser amount of ethanol. Not sure if that's correct. I haven't checked, but wonder if the percentage of ethanol is displayed on the pumps.

Re: Gas confusion
Premium has the same ethanol content. The only thing that changes are the additives.

Re: Gas confusion
Lucky to have a station with non ethanol premium nearby. Just bought some at $3.89 a gallon.

Re: Gas confusion
In Wisconsin I can get mid-grade (89) and premium (91) without ethanol at Fleet Farm. Their regular (87) has 10% ethanol. I use the 89 in lawnmowers, boats, chainsaws, etc., and the 91 in the truck and a couple cars that require premium.

Re: Gas confusion

Most of the Casey's around here have regular unleaded, or 10% Ethanol. They are both 87 octane. We don't have anything more than 87% that I know of. I use the regular unleaded with an additive in all of my old cars and trucks. LockDoc

Re: Gas confusion
I purchase ethanol free fuel at either the small airport or the marina near where I live. This is what I use in all of my carbureted engines and I’ve never had any issues with the build up of deposits associated with ethanol fuel. I store my motors with this fuel and never use any additives like Sta-bil. Price is usually $.50 to a dollar more then gas station ethanol fuel.

Re: Gas confusion
Like been said before use non ethonal if available. If not use some stabil every fill up. Ethonal like all alcohols love to absorb water. And it's hard on aluminum and rubber .
We have non ethonal gas around me so I use that in my traucks and carbed vehicles and small yard engines. The pumps here say up to 10% ethonal so it could have none or 10%. Haven't seen the 15% here in NY but I have in PA . E85 is available

Re: Gas confusion
Another station started selling non ethanol just a mile away. Great to have 3 local choices.

Re: Gas confusion
I emailed Kwik Trip/Kwik Star directly about the ethanol content in the 91 Octane Premium- "At our locations, we have different blends of premium gasoline depending on the region the location is in."
"Both locations in Maquoketa are going to be Premium 91 Octane fuel with no ethanol added." Looks like the BP in Center Point has 91 octane Ethanol-free

Re: Gas confusion
Some Conoco stations here in the PNW have 91 Octane non ethanol and that is what I run in my boat and my small engines. I'll run it in my 71 with the 500 Cad when it hits the road too. The engine will need premium with the early heads.
