I thought I’d try sea foam for winter. I had read general accounts-fill up and add a can then run long enough with the generator running to get the treated gas through the system.
I bought two cans to try but the directions are confusing me. Calls for one ounce for every gallon of gas. 55 oz? Really? Then directions are to add to a low tank of gas for a higher concentration as it runs through the engine. Can’t do that I filled it for the winter already.
Is one can enough for storage? Do you really add 4 or more cans when storing your RV?

Put 1 oz for every gallon of gas in your tank. Run the engine and generator about 15 minutes shut them off until winter is over or you need to exercise genny.
In your case this would be 4 cans of 16 oz each for a 55 gallon tank.

Next year, don’t fill your tank before winter. That’s another old wives tale. You don’t need to worry about moisture in the tank unless there’s some extenuating circumstances.
And even if there is a bit of condensation, the ethanol in regular gasoline will eat it up no problem.

You really should add it before you fill, as with any additive so it gets mixed well when you are filling your tank.

So what happens if you use less than the recommended dose? Like maybe half of it.

What happens if you only take 1/2 your medications each day.

I wonder how many car, tractor, boat, and plane dealers run around their lots putting Seafoam in the products sitting there? Hmmmmm.
