aging gasoline

[windknotnc]

Did you winterize the engine? You didn't mention what kind of engine it is. 2 Stroke, 4 Stroke, Carbed, FI? November is not that long ago and I would doubt you need to squirt oil in the cylinders. Give us more information and I am sure you will get some good experiential advice.

Is it gasoline with or without ethanol?

Chevron states their gasoline can be stored for a year without deterioration when the storage conditions are good — a tightly closed container and moderate temperatures.

Most gasoline is used within a week or two of purchase. But there are occasions when gasoline is kept longer. Examples are gasoline stored to fuel small-engine equipment or to provide a backup supply for a vehicle. Also gasoline left in the tank of a boat stored for the winter or a snowmobile stored for the summer.

Chevron recommends that gasoline not be stored unnecessarily. A supply that won't be needed for several months should be used and replenished when the need reoccurs. Gasoline that is in good condition can be added to the fuel tank of a gasoline-fueled car or truck. (Don't dispose of gasoline-oil mixtures for two-stroke-cycle engines in this way.)

However, when storage is necessary, this bulletin describes how to do it properly and safely.

The term "container" is used collectively for storage cans and drums, storage tanks, and vehicle and equipment fuel tanks except when the discussion is specific to only one member of the class.

Brent, does Chevron give Marine gasoline advice? Boats with built in gas tanks, like a Parker are not sealed gas tanks, they are all open to the air thru a vent. But Chevron does sell gas and must know their product. Engine was not winterized, went straight into high dry after being run on fresh water, drained and then put on a rack.
By the way where does one get gas without ETOH (10%) in the USA?

I would ask the marina for their fuel supplier and call them for the specifics

we only get 200-250 gallons at a time in a above ground tank.no savings in bulk unless you count not towing my boat around to fuel up.do not worry about treating for storage.never sits around to long between the boat and farm use

I stored my boat several winters with treated e-10 gas with no problems.All I did was top the tank off with fresh and changed my filter.I did pour the old gas out of the filter and dumped it in a jar just to look for signs of phase separation.Your nose can sometimes be the judge of gas.Just my 2 cents worth but everyone seems to have different opinions.

So, from what is being said, or not said, I should not be to concerned about my treated fuel for this spring is that right?

Correct.
If it was treated when the boat was stored, you should be good to go this spring. :wink:

 

[Megabyte]

Not sure about Sta-Bil, but I do know that Star*Tron and Ringfree both say that you can't over-treat.
I think this is due to the fact that they have both a 'maintenance dose' as well as a 'shock treatment dose', with the shock treatment being a much higher amount per gallon of gas.

When I pull up to the fuel dock, I'll look at my fuel computer and estimate the amount of fill according to what the computer says I've burned.
I'll then put my fuel amendments in the tank before I fill up to give me a good mix.

I always seem to estimate a bit low on my fuel fill, so I routinely 'over-treat' by a few ounces. It's never ever been a problem for me.

 

[pmeggers]

I use the same method as MegaByte.

However, if I fill up knowing that within the next 3-4 days I am going to blow through most, if not all of the tank, I may lighten up on the additives or not use them at all.
