In some states, premium has no ethanol. In some gas stations, particularly those near to marinas there is no ethanol in their gas, regular OR premium. 

 

But in NJ, every gallon of gas except avgas has ethanol. But avgas has lead.  But probably not for much longer if the EPA has their way...

 

Here's a site that lists ethanol free gas stations:

You can also use an ethanol treatment for the tree hugger ethanol contaminated gas that comes out of our gas pumps. 

 

Oh, and speaking of tree huggers... it is likely that ethanol in gas is actually WORSE for the environment than gas made strictly from petroleum. This is because to grow corn, you need fertilizer and diesel fuel (for tractors and farm equipment). 

most people are reporting less MPG on ethanol gas

 

No kidding! Before NJ started using it, I used to fill up in NY and NJ. NY had ethanol, NJ did not. I got about 3-5MPG better on NJ gas than NY. 

Just an FYI,  We used to run automotive pump gas in the airplane!

I only buy Stihl equipment and the two places I've bought stuff from over the years both say to only use premium. Since they not only sell the stuff, but also service it, they say the can instantly tell if a 2-stoke motor was run on regular or premium. Since the lawn guys beat the heck out of equipment and get their stuff fixed by them, I trust they know what they are talking about. So I will only use premium for my stuff.

I run it my pre 1945 Motorcycles. I would not run it in anything modern except a plane. It is high octane and leaded of course.

Some aircraft are approved to run on mogas (it's great when they are), but unfortunately most piston planes are not.

Yes I know, there was an STC for it.  It was a  '69 Cessna 182   

 

Of course the FBO didn't like it. 

 

 We made up a trailer with two 55 gallon tanks,electric fuel pump, fuel hose, and a nozzle

 

 I too used to run a mix of 100LL AG and Sunoco 94 in my  '69 Z-28 with the 302.

A friend of mine told me he used to run mogas in his plane years ago. Now, not so much... in fact one of the things he has to do now is sample some fuel from the tank for moisture now. No go with ethanol blend fuels.

Checking for water in the fuel is part of any preflight inspection. That is not something new. 

 

Light aircraft are equipped with fuel drain valves.

 

The wing sumps are checked as well as the belly sump to identify if water is present in the fuel.
