Re: OLD FUEL
From Exxon.com:<br /><br />" <br />How long can gasoline be stored?<br />There is no single answer to the question of how long gasoline can be kept in storage, because the answer depends upon the conditions under which it is stored. Gasoline in storage can change in two primary ways. It can lose light ends (volatile components) and/or it can oxidize. In addition, gasolines blended with ethanol can absorb water and separate into a gasoline layer and another water/alcohol layer. <br /><br />Gasoline should generally be used within a month of purchase. When the engine will not be used for an extended period of time, the conservative approach is to drain the fuel tank and then run the engine until it stalls. If you choose to store gasoline, keep it in very nearly full (minimizing air contact) tightly sealed metal containers (minimizing the loss of light ends and the availability of humid air) in a cool environment (slowing down the rate of oxidation). Be sure to leave some room in the container to allow for some expansion. Under these conditions, the gasoline would be expected to remain of good quality for at least 6 months."
