Is it necessary to put stabilizer in the fuel at every fill up? I have a friend who sugests that I do. I run my fuel tank empty at least once every three weeks. I told him that I believe that stabilizer would be used if you anticipated not using the boat for a prolonged period. If I'm right, the folks at Sta-bil really like my friend because he uses it in every tank run through his engine even if it will be used in a couple of days.

No you do not need to use a stabilizer if you are using a tank that fast. You can add the stabilizer at a later date if you do not use it up right a way.

Re: Fuel Stabilizer

I would think that even refilling a half full tank of 6 month old gas would be sufficient to recharge the whole tank. Do you agree?

Re: Fuel Stabilizer

i would think so . on another site ther was a discushion about that and some recomend topping off a tank when storing it to keep moisture from building up and some sayes lie you said half tank and top it off when going fishing to rejuvinate it . the teck said either one was acceptable .

Re: Fuel Stabilizer

this is the post on that subject. i will post the teck in the next one . Here in CT, the gasoline has 10% ethanol content. The 10% inclusion was required beginning 1/1/04, so not many of us have started our motors since winterizing them since the Oct/Nov timeframe. After discussing the topic with others in the area, we've collectively concluded that the fuel stabilizer used in winterization is predominantly derived from alcohol - similar to ethanol and, therefore, should not present significant problems come spring.<br /> <br />Secondarily to this issue is the amount of gasoline left in the tank upon winterization. One camp believes that the tank should be filled to the top to leave as little room as possible for condensation (water) to collect. The other camp believes that you should leave the tank half-full to allow for a mix of fresh gas at the beginning of spring. The later is based in the belief that both the ethanol and stabilizer will absorb the moisture and the fresh gasoline will help increase any lost octane from the old gas.<br /> <br />Anyone here been through a season with ethanol?<br /> <br />Anyone here have an opinion or just want to chat about the issue?

Re: Fuel Stabilizer

We have had to deal with it for many years up here already. When a customer comes in with a fuel problem, we first ask him/her what brand of fuel they are using. For better operation of Marine engines, we say to stay away from Eth blends.<br /> <br />As for your Half full or full. Its entirely up to you. Both work well.<br /> <br />TMD

Re: Fuel Stabilizer

It certainly doesn't hurt to run Stabil with every tank but I also feel it's unnecessary if the boat is used very frequently. I would suggest instead, using SeaFoam or similar fuel conditioners to keep the system clean as well as stabilizing the fuel regardless how frequently the boat is run.

Re: Fuel Stabilizer

Perhaps using stabilizer often comes from OMC/BRP's 2+4 fuel additive.I think 1 oz to a gallon is suggested to help keep help carbon and moisture out,and double strength for stabilizing over the winter.<br /><br />DHP

Re: Fuel Stabilizer

Ive heard alot of good thingds about Seafoam. I have that on my needs list. I new a guy who used to mix Marvel Mystery Oil with his gas. He swore by it. I assume Seafoam is a similar product. <br />Thanks for the xpert info,<br />Tim
