Thought I would change the title to try to get more readers.
This article, written by highly competent chemists,suggests many of the commonly accepted ideas about ethanol are WRONG!

Great information and very interesting.
Thanks for the info. That is definitely the opposite of what everyone has been saying. Can’t wait to hear what everyone else has to say about this article. Good to know!

Nice article, but it doesn’t take 75 years in the Gasoline Industry to know that if you use blended fuels, and don’t refresh often, you’re gonna have problems! Just read some of the submissions from folks who’ve tried.

That was wrote by two CE’s, both whom work for the oil co’s. I prefer to stick to actual first hand experiences.
On another note, yesterday just ran 200 gals of 8 month old star-tron treated fuel without so much as even a hiccup out of motors.

Tanks full, that’s what I’ve always recommended for exactly the reasons given.

Top 2 bottom 200 gallon burn hope there are tales of tails to go with that expense
Where are the facts… all this article tells us is an opinion… They say it right in this article that e10 will hold water 1/2 percent by volume… well the less volume the less phase separation… I leave my tank as empty as possible and have very little to no water or particles in my filters… I will continue to do so and still ad stabilizer… I use my boat at least once every couple weeks on average… There are a lot of videos and studies on the net… If I have time I will post some that show FACTS to do the opposite of what the above article advises…

The article was not all opinion; there is factual information.
When they say E10 will hold 1/2% by volume of water that is the amount of water that can be absorbed before phase separation occurs. Lets say you have a 100 gallon tank. At about 7 pounds per gallon, a full tank will absorb 3.5 pounds or 54 ounces of water before phase separation occures. With the tank full there is very little air space which means very little water vapor. In fact, fuel vapor will tend to displace any air from the tank as they are heavier and push air out of the vent. Therefore there is a very little chance of the fuel absorbing enough water for phase separation to occur in a full tank.
Now lets say you keep the tank as empty as you can, let’s say 5 gallons is left. It would only take .175 pounds or about 2.7 ounces of water to cause phase separation. Now with an empty tank you have a large volume of air and water vapor in relation to the amount of fuel. As the tank breathes due to daily changes in temperature it draws in more air and entrained water vapor. Water is absorbed into the fuel directly from the air and by condensation within empty tanks.

and after 2 months, you still have 100 gallons of very low octane fuel, that may not have seperated, but it WILL grow slime, and cause major detonation issues, and VERY bad for 2 strokes. isnt 3 ounces of water, alot easier to deal with, than 100 gallons of skunky fuel?
hairball, I completely agree with your science, its just the end result I have daily issues with

I hear you Chris. If the boat is used on a regular basis there is no need to keep the tanks empty. Extended layups are best done with an empty tank. I’m not convinced that all fuel goes bad in 2 months. A lot has to do with how a boat is stored. Boats stored outside without a cover or a bad cover (like a tarp that doesn’t breathe) are most susceptible for problems. I’ve witnessed this on a small scale with gas cans. My neighbor contiually has problems with fuel for his riding mower. He kept his gas cans out of the weather, but they were exposed to sunlight and a high fluctuation of temperature each day. I told him to keep them in a more controlled enviroment like in a ventilated shed and his problems went away. I think that most people have problems due to they way thier boat is stored. There is no reason that fuel should become skunked in 2 months under good conditions with a conditioner/stabilizer added.

LOL, all fees will be graciously accepted:smiley:. I used to work as a consultant for a local marine engine manufacturer; at least until the economy went belly up:face_with_head_bandage:.
P.S.
Thanks for helping my friend out about a month or so back. He bought the 21’ SeaPro bay boat from you. He said you were great and he really appreciated the time you spent with him.

Personally, I keep my 55 gal tank full during the Winter months, treat the fuel with blue Stabil and run the engine on the “ears” several times during the off-season.
I have run last season’s gas successfully on several trips this month-burned about 25 gals-with no problems.
Knock wood this method works; so far so good.

I too keep my engine full during the winter and use marine Sta-Bil. Just changed my 10 micron fuel filter and decided to see what was in it. Poured out contents and all gas. No slime or water mixed in. I ran boat at least once a month though, running 30 gallons or so each time, replacing with fresh and more Sta-Bil. Engine purrs like a kitten.
