Why store with a full tank of fuel?

[Jimmy N.]

I...so I wouldn't think topping it up is needed unless you guys worry about condensation some how? I'd wonder if the fuel is still any good after storage for 5 or 6 months? .

I have yet to find any condensation in any tanks here, including metal storage tanks that are exposed to the sun. Going on three years with gas for the vehicles that get fueled up at home.

The greatest contributor to condensation...is variable temperatures...

Yeah, that would be logical, but...we often have 50 degree differences between the low and high temp in a day, and tanks in the sun would be subjected to a bigger difference.

If there's little to practically no humidity where would the condensation come from?

Like I said before, I'm not running my car at the track with gas that has been in the tank for 5 months. I still don't 100% know if leaving e85 in the car is ok. But for me putting 5 gallons of 93 in it for the winter and draining it out to switch to e85 works fine. By the time I drive my car to storage and drive it back in the spring may be 3-4 gallons left. I then use that gas in my lawn mower for the year which I don't even go through all of it
