Storing with gas in tank, for a year or more?

Oh man i love Startron for gasoline (especially gas with ethanol). Archoil for diesel. If you dont have a fuel jug a regular water bottle will hold gasoline for years and not leak. I would get a gallon of fresh gas and mix up your starTron concentration for whatever size tank you have. Then just rock the van back and forth. It will mix.

What state did you buy the gas in? Maybe youre lucky and have non ethanol gas.

Curious to learn more about what the gentleman said regarding engine temps and evaporating moisture. Of course the differentials will stay cold. But wont the motor oil itself get to operating temps and boil off the water?

Its the reason you never want to buy a used car from someone who says "barely use the car i work 5 mins away from home".

It states so on the can that it stabilizes fuel for up to 2 years. I have not gone that far but have gone a year on my generator without any problems.

jdc1,

I tried stabil. It did not work well in my generator. The next year I tried seafoam. It worked well. I only use premium gas in the generator.

I've used seafoam for 2 years in my car, for a 4 month storage period. I switch to premium gas for the last two fill ups.

I use seafoam for summer and winter storage for the motorhome (class c v10 from 2005). I switch to premium for the last two fills.

Seafoam did not work well in my generator for an 18 month storage. I had to add some gas treatment to clear out the old fuel.

My brother has also switched to seafoam from stabil. His vehicles are stored for up to ten months per year.

This is not proof. It is anecdotal.

I've been using Sea Foam as a gas stabilizer in my small engines for years with no problems.
They always start easily in the spring/winter.

Seafoam? For a gas stabilizer? Hmmmm.....

How far was it driven after being filled?

Perhaps there is room to add some small amount of gas? (premium preferred).

If so, get some seafoam, put the appropriate amount in the tank, and pour in the premium fuel to "wash it down into the tank".

It would be a good idea to run the engine for some time the next day after the treatment has had time to mix.

I find seafoam better than stabil.

Running you engine every month without driving the van is a really bad idea. The engine and oil will not get hot enough to boil the contaminants out of the oil.

I,d put stabil in it and run for a half hour or so. if possible run it every month for a half hour. the viberation might mix it .

I wouldn’t store gasoline in a vehicle for a year with or without any stabilizer. “If you’re asking for trouble, Pilgrim, you’ll likely get trouble.”

My research shows startron is not for keeping fuel viable. Stabil is, but 'up to a year.'

I regularly leave fuel in my car over the winter for 6 months sans anything, and it's fine. Gas without any additive is good for 6 months.
