After reading on here about the benefits of ethanol free,I realized there is a gas station less than 10min from where I live that has ethanol free gas. Guess I’ll at least fill up there when convenient. Plan to fill it up soon for winter storage/carb work and add some sea foam.



A little pricey though. I can get regular 87 for $2.85 a couple minutes from home.

I used E0 in W.Va. and N.C. when available. Other than the water absorption problem, I found no improvement. Not power or fuel economy. Also, the water problem is a storage problem, and if you fill the tank all the way, not much of one.

That’s good to know because it’s about a $1.45 more a gallon then regular 87 at the nearest gas station two minutes away

I use E-10 87 octane all summer. Late fall before weather gets bad, I switch to 91 no ethanol for storage. As a tech who has cleaned hundreds of carbs due to the effects of ethanol during extended down times, I'm not risking it in my Valks. Not putting sea-foam in mine either.  Sta-bil only. YMMV

SeaFoam is not great for storing gas for more than about 2 months, less depending on where you live. Plenty of tests show that Sta-Bil works a lot longer, you just have to get the right version.

I only run pure non ethanol gas in my bikes, and all my gas powered equipment.  Last count, I have about 35 carburetors at my house, and I am an incompetent carb repairman.

Non ethanol is prohibited from sale in my NoVA counties which are run by the left who I assume are trying to save the planet.  So it's 50 miles West to the closest station that does (there may be a closer boat marina that sells it, but without road tax, they would probably give me a hard time lugging 40 gallons in cans back to my truck).  Out West is where I always ride, so I always top up out there before coming home.  But for all my other gas equipment and occasional bike use, I drive my truck out there 3-4 times a year, and get 40 gallons in cans, each treated with marine grade Stabil. 

We can only get 87 octane pure gas; never seen 91 octane anywhere.

Ethanol polluted gas will run in everything, but if you let it sit in bikes and equipment (esp in hot sheds in summer) it grows green mold leading to carb repair headaches.  Equipment I use all the time (mower, blower, weedwacker) sit with gas in them, but things I only use on occasion (pressure washer, generator, chainsaw) do not, and get drained and winterized after use.

Making 100 mile pure gas trips about quarterly is a PITA, but I am rewarded by never having carb headaches in anything.  And as a matter of principle, I do everything I can to NOT save the planet when it comes to using ethanol polluted gasoline.

seafoam has additives that eat away at the OEM Buna-n  aka nitrile o-rings over time, just use sta-bil its safe.

YouTuber "project farm" just released a 5 year comparison on gas storage additives.

You can search for it yourself.

His comparisons of all things relevant to today's living are excellent and professional.

For winterizing I use 91 octane with no corn liquer in it and add a healthy dose of Marine Stabil before heading to the storage location 3 miles away. By the time I get there, it's all well mixed so I just shut it down and pull the battery. I have a different storage unit this year, still only 3.5 miles away, brand new and easy access. Might keep it year 'round.

Got Nancy giggling cuz right next door is a barn yard with a herd of milk cows. My unit is in the last row nearest the barn yard with a small catch pond in between, so when I pull in I suddenly have a large audience staring at me. Other day I stopped and looked at them, then started making various noises at them as I did when a kid on the farm during summer. Shortly I had a regular chorus going, a rather moooving experience for a city girl.  Grin  I used to spend summers on the farm with my two cousins, I'd tell my girls how we had to go milk the cows by hand early before breakfast. Then at the end of day after working in the field all day we still had to milk them a second time and we were always dog tired by then. My girls asked how we three boys were able to do that at the end of the day since we were sooo tired. I told them we figured out a way to teach the cows to jump up/down so all we had to do was hang on. A little past 8 years old they never believed me...on most everything.  Wink

Someone told me you can buy ethanol free gasoline online and download it through your computer or phone. I think it was John Schmidt who told me that.

I'm a big fan of Project Farm! I wont buy anything without checking to see if he has tested it first. Great stuff. Independant, and no sponsers..

Also, I like Torque Test channel, very good test guy too.

Those 2 have cost me a lot of bucks!  Grin

Thanks, looks like I’ll be using Sta-Bil

Several years ago my old BMW R100 GS had been sitting with E10 in the tank all winter. It wouldn't start when I tried in the spring. It only takes a second to pull the bowls on those Bing carbs (they're held on by a single spring clip) so I pulled one and could see blobs of water floating around at the bottom. I dumped both carbs bowls, filled the tank with fresh gas, and it started right up. That was an ethanol lesson I never forgot.

Now I have a Murphy Express 2 miles away with ethanol free gas that goes in all motorcycle and power equipment engines.

Getting ready to put her away in a few weeks and try to pull the carbs for refurbish.  Should I store with the tank full w/Sta-Bil or should I run it almost dry/drain the rest and put the gas tank in the basement?

I've always heard that it's best to store a tank either completely full or empty. A half full tank allows a large surface area of fuel to be in contact with the atmosphere, increasing the amount of moisture that gets absorbed by the ethanol.
