Ethanol!

[airshot]

Well....guess I will add my experiences with E10 fuel....in the early days, I followed the fuel recommendations and changed all the fuel hoses to E10 compatible hose. Cleaned out my fuel systems and started using E10 fuel. The only issues I have had in all these years was caused from buying contaminated fuel to begin with. I did a lot of fuel testing before I was able to find stations that actually sold clean fuel with no water in it ! When I did find poor fuel, I reported it to the station owner then onto the county inspector if the owner did not correct the problem. Did not take long for the word to spread about dirty fuel. The local farmers group started a co op station for bothering gas and diesel including E0 fuels. I have never found contaminated fuel there nor has anyone else. We have a few old car collecters that come in and use the fuels at this station just because they know the fuel is good. My neighbor is one of those collecters, he has a dozen old Mopar high performance vehicles, including the 440 Magnum, Super Bird, Road Runner and other of that caliber. He and I have been using E 10 fuels for decades, never an issue as long as we treat it on purchase.
The cost of treating the fuel is cheaper than paying and extra fifty cents a gallon or more for the E0 fuel, and even that should be treated as it will go bad over time. I was a mechanic back in the later 60's and 70's and cleaning gunk out of carbs and treating fuels with " gumout" was very popular. When the E 10 fuels came out, the local drag racers were fighting to get it as their cars ran better and faster with it....your money, spend it now you like, but if your buying E10 and have an issue, look deeper than just blaming it on the E 10 gasoline itself.

E10 is a big boon. When a mechanic can't figure out what the problem is (was), now he has something to blame. Lots of reading to be had if you google the myths of ethanol.

My old 1980 Ponch has been running on E10 since it was first available. Never had a carb problem. My 1952 'Rude Big Twin has also had good luck, though the fuel lines and carb have been replaced with ethanol resistant parts.

A few years ago a Consumer Advocate group quietly did a survey of a number of different gas stations. They took samples and had a lab analyze them. E0 ranged from 0% ethanol up to about 10%. E10 ranged from 0% to about 15. It's obvious that you never know what you might get. I don't know if things have improved or not.

To follow-up on my original post.....I drained the tank and refilled it with E0. ($5.19 a gallon was a hard pill to swallow - fortunately the tank is only 0.3 gallons). I will add Seafoam to the mix as well.

Unfortunately, Summer is waning and I don't expect to get time for much running any more. I suspect my root cause is lack of use, but that has to do with the motor's purpose. It's a 2016 and has about 7 hours on the clock.

Thanks to all for the replies.
