Gasoline with alcohol in it can be a little hard on rubber lines on older vehicles, not so much with vehicles sourced to run with a little alcohol.



yep, I run 10% in my vehicles but all of my mowers/etc. are run on alcohol free gas. My friend who owns a boat/motor/etc. repair business has an assortment of ruined engine parts on display due to ethanol.

The price differential between E0 and E10 is a primary reason NOT to use E0, except perhaps for small engines that aren’t used very often, or if you have a vehicle that runs like poop with E10 (which is doubtful)

If you have a vehicle made in the last 25 years and drive it regularly there's no reason to avoid ethanol unless you want the extra MPG that pure gas gives. Yes, it really does as was pointed out, there is less energy in ethanol thus worse mileage. That's just physics and math.
I put ethanol in our modern daily drivers all the time, no problem. I never put ethanol in my boat or my small engines and I never will if at all possible. I also don't put ethanol into classic automobiles that were not designed for it. The hoses, o-rings, and other rubber parts will degrade, again, that's just chemistry, nothing you can do about it.

In a modern car, meaningless

In lawn equipment, absolutely go pure gas

My lawn equipment says 10% is fine. I have never had an issue, and I use no stabilizers over the winter. Everything starts right up and runs fine.

We have had E10 here for 40 years and after a few years of worrying about it and driving all over for "pure gas" I gave up and ran E10 in everything, including lawn equipment, snow blowers and marine engines. I have never had any issue with running, storage, gummed up carberators or failed rubber hoses as stated "on the internet". This includes a 20 year old mower and a 19 year old Mercury outboard. MPG may be a bit less but price more then offsets that.

It is not good for small motors like, chain saws, lawn mowers, outboard motors, generators, golf carts, pressure washers, motor cycles, snowmobiles etc etc.

I'm not even convinced that you get better mileage from 0%. The computer in a modern vehicle controls every aspect of the ignition system and knows what fuel you are burning. It adjusts accordingly. Of course, YMMV as they say.

In other words you really should just test it out. Run a couple of tanks of each and compare.


I have to say I'm not either. I average city and highway just at 40mpg from my 14 Focus hatch with a 5 speed. Winter, summer and I run in the summer with the ac on all the time. Don't think I could do much better with non e gas but then I've never tried it because here, non e gas is about 15 cents a gallon more than 10% so there would be no savings at all.

My Focus is a flex fuel so I cab run E85 as well but never have.

I don't think that we have any 100% gas in my area and if we did it would depend on what the price was if I would use it or not. I hate using 10% in my chainsaws but I don't think I have a choice. I do put premium in them though.

If anybody has any doubts as to ethanol giving less mileage then try some E85 and you'll find out what it does. I used it one time and won't ever again unless I have no choice.
