How long does Stabilized fule last?

[Tommytuttle]

I am looking at buying a boat which has sat for 4years. It has a built in tank, the fuel has been sitting for 4years with fuel stablizer added when stored.<br /><br />What should I do with this?<br />Pump it out? And then What?<br /><br />Or is it safe to run?<br /><br />Thank you for your help.

I wouldn't count on the fuel being good for much over a year. This is what the stabilizer people claim and thats if you start with fresh gas. I think you'll save yourself a lot of headaches if you get rid of this gas and start fresh.

i agree, i've made the mistake of using gas that was stabalized, but had been sitting more than a year. The engine didnt run right at all. Plus if you have a metal tank you could have debris in there, or worse water. I would siphon it out and make sure the inside of the tank is good and clean and start with some fresh gas.

Drain it, or take a chance of ruining your engine. Your choice.

Also keep in mind that if it's a two-cycle <br />engine that there's a gas/oil mixture in there <br />and you can't legally siphon it out and just <br />dump it somewhere. It can be pretty expensive <br />to dispose of it properly.<br /><br />If it is a two-cycle, Service places can do a <br />test on it to see if it contains any water and <br />if it doesn't they might be able to add some <br />stable and get the fuel to the point where it is <br />useable. Not great, but good enough to burn out <br />rather than dealing with costly disposal.

Sta-bil advertises to keep fuel fresh for one year. Briggs and Stratton has their own brand stabilizer and it is advertised to keep fuel fresh for 2 yrs.

You also may be able to dispose of that gas by adding it to your car or truck. I dont do it often because i've heard that oil can clogg up the fuel injectors, but if its carborated then there shouldn't be a problem. Also if i do that i add only like a gallon or so each time and top off with fresh gas immediately after.
