91 Octane at the Pump

Well it may not call for it but with all the Polaris ATV's I've had I have come to believe that there is an issue that comes with the ethenol in the 87-89 gas. Most all fuel parts are constatly needing replacement do to dry rot and other things. I want to switch to 91 without ethenol in it to see what happens. The price is about .20 more per gallon but in the hundreds of dollars I have spent on rubber parts I could buy ALOT of 5 gallon gas cans of premium for the $.20 difference in price....Now there is looks of 20% ethenol soon!
I've put $290 into rubber fuel parts. At $.2 difference in premium that would have bought me 1450 gallons of 91 if that has been the issue to start with.

I live in Kalifornia and we have had eth in our gasoline since the 80's. Then we went to MTBE. Then back to eth again.
I have had some minor issues with fuel lines early on. No big deal and NEVER any carb issues.
I have equipment I use only 2 weeks out of a year. I used to put stabil in it. One year, many years ago, I forgot to put it in at the end of the season. Never messed with the stuff again.
The gasoline sits in it all year long in a vented tank. Never any problems. Last year I lost my crop and the gasoline had to sit in the tank for two years. Two weeks ago I had to crank up all my engines to test them out. All of them started just fine and ran just fine with two year old gas in them.
One of those engines is a Huskie two stroke leaf blower. It had gasoline in it for two years; with mixed oil. It cranked right up and ran perfect for about twenty hours. It runs WOT until the tank runs dry. It's fueled up and same thng over and over again.
All of these engines had eth gasoline in them for many years. Something else is up besides your gasoline.

Kalifornia??? You mean California? Anyhow, ethanol burns hotter and is more corrosive than "gas". The E-85 engines all have stainless steel components (rods/lifters etc.) They also have more water content. Not Good. I was under the impression that I should only run 87 octane or 93 octane. The 89 octane contains a chemical to blend the two which isn't good for the engine either. Put half 87 and half 93 if you want a boost. IMO

I think the main reason for the non-oxygenated gas is because it is supposed to burn cleaner in non-catalyst vehicles(cycles, atv's, small, engines, collector cars)and doesn't break down as fast. I agree that running 110 is a complete waste of time/$ unless your ride is modified(much higher compression than stock) to the point of needing the higher octane. The 10% ethanol shouldn't be a problem. Any newer fuel injected engine is designed to run on it. The problem was the MTBE blended crap. Sea foam occasionally is a great idea and stabilizer is a must if it sits idle for extended periods of time. I think Doctorturbo lucked out because CA has way strict standards and more than likely still adds plenty of stabilzer to their pump gas. His 2 stroke can sit longer because the oil mix for the gas has stabilizer in it. I typically run 87 octane except for the winter because my wheeler sits idle more and haven't had any problems.

magnum ,are you sure the 91 blend is ethanol free?? it's just that i live in central illinois and i deliver the squeezin's everyone is writing about. with 93 octane premium and 87 octane at the rack it's too much of a hermorphadite blend to do it . to make 91 octane --it takes 55% 87, 35% 93 & 10% ethanol. not saying that your station doesn't have ethanol in it but you should be sure and ask.around here there is only one dealer that has 87 straight product, all else has ethanol in it.
