I have used fuel stabiliser in the past, but that was long before ethanol became the E.P.A.'s oxygenate (so long M.T.B.E.) of choice.
Besides keeping the tank as full as practical, what product do you use? And, is what you have used specifically formulated to address the effects of ethanol? In particular I'm interested in your real world experience but all input is appreciated.
I have not used fuel stabilizer because on one of the Ts we used to own, the previous owner had used it and it left everything sticky that it touched. I have just used the regular ethanol gas in the past. I have had problems with vapor lock and most of the guys around here have laid it on the alcohol in the fuel. They said they are going to QTs alcohol free gas because it stops vapor lock. I cant say I have had trouble with "old" gas, that is 5 or 6 months old, going "bad" in my cars.
Fuel stabilizer has ZERO effect on ethanol.
There are many many stations that sell non-ethanol gas.
I've ben using 10% ethanol gas for years with no trouble so far. Never use stabilizer either. Keep gas in mowers, lawn care equipment, my Model T, etc. with no problems. Last week I started up my lawn mower that takes regular gas. First start since September with about a half gallon in a two gallon tank. Started right up, now problems.
We have been following this subject for many years in my other hobby, military vehicles. We have not come across or heard of an additive that will prevent ethynol gasoline from turning to glue in an aspirated fuel system.
We are advocating running on "clean" gas and most do so. It seems that if you go through a tank of gas rather quickly and then use clean gas for your last few tanks of the season, trouble can be reduced.
A fuel wholesaler nearby sells clean gas and we fill up our vehicles and jerry cans for use to top off and for outboard motors and lawn equiptment.
That last line should read "no problems."
Me too. I don't worry about any of that.
Tim's right. The stuff has zero effect on ethanol. It also has zero effect on regular old style fuel. It does have an effect on your wallet. Makes it lighter.
Hmm, funny, fuel is never in my tank long enough to need any stabilizing. I just run it until it's gone and then refill and repeat.
I heard all the war stories about ethanol in the gas but didn't pay a lot attention to them. That was until I tried to start my mini-tiller for the garden. I use it about 6 times a year and store it in the barn. It would not start and I checked to see if there was gas. About a 1/4 tank. Fooled around with it and finally took the carb apart. Some gas fell on the concrete as I opened the carb and I noticed water droplets bouncing on the concrete. Pure water. I don't remember this happening when I used non-ethanol gas for years.
A lot of folks I know around here in lake country use Marine Stabil in the outboard tanks. I use the stuff in my yard equipment that just doesn't go through an entire tank between uses. I've also used it in the Model T to some extent. But most of the time I prefer to just bite the bullet and use non-oxygenated fuel. My rule is that I don't like letting oxygenated fuels sit in the tank for any more than 30 days if the equipment isn't being used. Leaving a tank full doesn't seem to make much difference in preventing water from accumulating in the gas tank. Just one of those realities you have to adjust to I guess.
Never used the Sta-Bil stuff until about two years ago.
Then when I did, it made the gas coat the inside of an Edelbrock 1405 with a white, sticky mess.
I quit using it and haven't had the same problem.
I've found that the 10% ethanol they sell around here has a shorter shelf life than non-ethanol gas, but it'll still last several months without degrading too much.
R.S., you are right. Ethanol fuel draws moisture like crazy. It also coats everything with a yellow-ish residue. Something from the corn just maybe? If I had a dollar for every time I've told "my story" about learning the value of adding StaBil every fall to my '94 T-bird when I lay it up for the winter I'd be rich. I swear by it. So does the T-bird, believe me. Nuff said. Was just at a fellow club member's place this week in my '20 and we got to talking about how short the shelf life is of todays gasoline. He said he had some gas he that he used to clean out an engine pan with some baffles in it. Couldn't get all the fuel out, so he threw a match at it..(from a distance), the lighted match hit the fuel and went out! Said he tried several times, same result. Not even enough volatile vapor to make a "poof". I've heard this before "through the grapevine" but never face to face. He wasn't joking. Today's gasoline sucks.
Ethanol fuel has had zero effect on any of my engines.
I have never had a problem with our California gas going bad in my T's. Even in the yard equipment, chain saws etc. They sit all winter and start right up in the fall. Never used any type of stabilizer.
I have had problems with old gas in my 4v Holley carbs. Front pumps stick and like Tim W. Said the inside of your carb will turn yellowish/ brown color if it sits for a month or so without driving the car. I don't always drive my mustang weekly any more. Just to much fun fooling with model A s and T s right now. Tim
And, if you have any shellac sealed cork floats or gaskets in your equiptment and the gas with alcohol gets to it, it will dissolve the shellac.
Many gas tank sending units back in the day had shellac sealed cork floats. Now they sink.
I donated a boat to charity one time a few years ago and the guy that picked it up said the first thing they do is clean the carb and pull out al the lines and hoses due to the varnish sticky build up of the ethynol gas.
