Fuel stabilizer is supposed to help, a lot. Let's split hairs:
Would adding fuel stabilizer after the fact turn stale fuel into good fuel? How much would you have to dilute stale fuel with good fuel so there wouldn't be a problem? We can all agree that allowing stale fuel to rest in a carb can varnish it up, but will running the engine with stale fuel cause problems? Drew "test" wrote in message om... Just for non mixed fuel. I'll agree with Drew, on 1 part of his post quote--"varnish your carb" I agree. I'm not so sure about Drews's quote --" Today's gasoline's go bad in 30 days." I own 5.4l mercruiser w/90 gal fuel cap, also Correct Craft 302 w/20 gal cap. I've had old fuel in the both 20 and 90 gallon tank stored over 9-to 12 months - aprox 45gals or more in big tank. If you ad "Fuel Stabilizer" along with some octane booster and of coarse some new fuel mixed in should be ready to go. The best advice is to RUN the motor frequently to move any varnishing on fuel Carb - jets. If I'm wrong please correct me or just feel sorry for me. Regards Ron Central FL. "Drew Shuller" wrote in message ... Harvey, Gould 0738's suggestion is the correct one. Even a gas/oil mix, when added to your car's tank in small quantities, won't harm your car's engine or fuel system. Today's gasolines go bad in 30 days. Using gas any older than that will varnish your carb/fuel system, and you really don't want that to happen. Drew Waco, TX "Harvey Arkawy" wrote in message om... I just purchased a used boat with a 1995 Merc 70 hp, 3 cyl. 2 stroke "Force" motor. The previous owner said that the gas (~ 17 gallons) was about a year and a half old. I would like to siphon it out into 4 five gallon cans. Has anyone done this and where do you suggest I dispose of it. Please be kind.... I know where I don't want to put it. I contacted the local Air Force Base Fire Department to see if they could use it to burn during a practice fire, but the local Air Quality Management Department (AQMD) required them to install propane burners and burn propane during fire practice. Any help or suggestions would be appreciated. Harvey |

Adding fuel stabilizer after the fact will not fix the fuel.
As for running it - depends on the engine. I would say you can get away with fairly bad fuel in an I/O and not have much problem - especially if you mix say 50:50 w/ fresh 92/93 octane. As for running it in an outboard 2 stroke - they will detonate and punch a hole in the top of the cylinder. You can probably get away w/ a 20:80 mix of old to fresh 92/93 octane but I would not go past that point. -- Tony my boats at http://t.thomas.home.mchsi.com "Drew Shuller" wrote in message ...

I don't know if the higher octane has anything to do with helping out with the stale gas situation. I do know that with my old I/O, the compression and/or timing was set up in such a way that low octane fuel caused knocking, dieseling, and my mechanic told me, would cause damage. |

Right, I understand that high octane fuel prevents premature ignition (that being the whole purpose of high octane fuel), and that premature ignition causes damage. Is old fuel more prone to premature ignition? That would be the only obvious reason for a recommendation to mix with high-octane fuel. Thanks, Shawn. |
