I also have old fuel. It's from october. 91 octane. I'd say about 13 gallons. It won't start on this gas. But it will start on fresh gas in the other tank. Are you saying I can salvage this gas!?
When you say won't start. What do you mean?
In all honesty, I'm thinking water in the bottom. Not the fuel itself.
The way you say it, if you pulled a little fuel out of the tank and poured it into the carburetor it won't burn. Is that the case?
Or will it just not start on that tank?
When fuel is stored in a tank that is full, there is no air space to sweat (condense) producing water in the bottom. Water is heavier than gasoline, so it can be separated out if you need to.
Whether a tank is stored at half full, several things happen. When it warms up, it gasses of pretty quick, this vaporizes the hydrocarbons that make fuel burn. The alcohol in most gasoline, used as an oxygenate, is mostly water, so it actually vaporizers much slower.
So what you have there could be a bunch of water laden tired gas.
Regular pump gas normally turns orange when it is no longer alive. It should be either clear, pink or look like apple juice. It depends on the additives.
Either way, the gas won't have the punch it did when it was fresh, but if it will start, I doubt seriously any of us could tell new from old. Besides the odor anyway.
