For you guys that aren't using your vehicle as a daily, remember that ethanol blended fuels have a shorter shelf life as the alcohol has an affinity to attract & absorb moisture, and water will cause the fuel to separate. Not an issue if you are using a tank of juice every week or two, but does become an issue if left standing for a couple of weeks or more, especially if the tank is only partially filled.
For those of you storing fuel in cans, make sure they are full & have tight fitting lids. Also keep them off the concrete, covered, & preferably some place the temperature is reasonably constant. This will help prevent condensation forming .
