Cold Storage - Car cover or not?

[Johnny Horsepower]

"The problem begins with today's modern fuels. These so-called "clean" fuels typically deteriorate at much faster rates than fuels made 20 years ago. While all fuels suffer from the problem, most at risk are the EPA mandated reformulated gasolines (RFG) that contain oxygenate additives, derivatives of methyl alcohol and ethyl alcohol. We've seen gasoline have shelf life as little as a month--particularly if it is subjected to heat and moisture. "

"The shelf life of gasoline depends on the type of gas and the storage conditions and can range from a couple months to a couple years. One wild card is that gas you buy at the pump may already have been in storage for anywhere from days to months."

A couple of quotes off the net.

I have a very hard time pouring anything into my gas tank but gas. I have stored cars for 6 months a year every year since I was 16 years old, and have never done anything but fill them to the top and forget about it. Usually it's either straight 93 octane or a blend of 93 and 115 racing fuel, depending on the car. In the spring they always fire right up and I use the 6 month old gasoline with no noticible difference from when I put it in there in the fall. Maybe i'm just lucky, but I've never used Stabil, or anything of that sort, and have never had a problem. Maybe if it was stored for a year or more things would be different.

Honestly I haven't either. My 69 has been stored in cold storage and most recently heated and never a problem with the fuel.
