To fill or not to fill

[TK246WA]

What does everyone do with your gas tanks for the winter, fill them or not?

I add fuel stabilizer then top off the tanks preventing condensation from forming. Adding the stabilizer before fueling then a run over to the marina helps make sure it is well mixed in and in my opinion gets it through the entire fuel system.

You can go both ways but make sure to tape or seal fills and vents because E-10 will attract moisture from the air. I emptied mine put stabilizer in and taped fills and vents. Did I post recently how much I hate E-10, 15, 30!!!!!

I always fill.

 

[Throwback]

Close to full and stabilizer.

 

[redneck]

I empty them.

I've always emptied mine. I rationalized that if the gas separated, I'd rather have a small mess than a big one. Knock on wood; I've never had a problem.

This year however, one of the nearby marinas has ethanol free gas, so I'm thinking about filling up instead of emptying.

We are fortunate to operate in an area that has plenty of no-ethanol fuel sources which allows us to NEVER load any ethanol enhanced gas in our tanks. Also adding Marine Sta-Bil 360 each fill-up per directions has yielded great results. I keep my tanks topped off year round.

Nothing.
Leave fuel in tank at level when boat was hauled.
Successful method after 22 seasons.

I read somewhere, possibly Consumer Reports, that almost all fuel additives/treatments are nothing but a scam. Think about it, how can a pint of the scam remove a quart of water from gas. I know the labels talk about breaking down the water so it can get through the fuel system; I am chemistry dumb, but how can water be "broken down" so it will go through a fuel system? Snake oil for sale. Don't use E-10 gas, ever.
