Aircraft storage
How long can an aircraft sit unused before the fuel gums up and contaminates
the fuel system? For instance, if I leave a motorcycle sit too long without a fuel stabilizer added to the gas, the gas goes bad after a few months and gums up the carbs. The entire fuel system is affected after a while. Big problem if you try to store an automobile without lots of prep since fuel lines and everything can gum up. What is the life of av gas before it goes bad? If it's like white gas it can sit almost indefinately. If it's like auto fuel it can't sit for long. I ask because some of these planes seem like they're for sale for over a year or more, and I wonder what kind of problems they have due to sitting besides the obvious dry startup with no oil on the cam etc. (as if that isn't enough of a problem) Alex -- My 2¢ YMMV |

It may be, but it's much more highly refined and can store for much, much longer than unleaded auto fuel without gumming up. Auto unleaded will only store for months, white gas may be good for years.

You've been fortunate to get a tank of extremely stable gasoline. Over the last few decades, I've stored a number of motorcycles in my garage for varying periods. I found that autogas would start to smell funny after a year. After 2 years, it transformed itself into something that looked and smelled exactly like turpentine. Needless to say, by the time the fuel got to that point, the carburetor jets were hopelessly clogged with a nasty gummy substance. If you use a gasoline stabilizer like Sta-bil, auto gas can last quite a bit longer. Fuel makers recognize that planes may go awhile on the same tank of gas, so they formulate avgas accordingly. Last time I checked, Chevron and BP both said their avgas would be fine after a year. John Galban=====N4BQ (PA28-180) |

It isn't a type of unleaded auto gas, it is a type of naphtha, which isn't gasoline and isn't benzene, but is between the two in the distillation process. Matt |

Maybe in some circles, but Amoco unleaded gasoline has been called "white gas" in the South (at least) since I was born (also at least). It's called that because it's clear.

I won't dispute that, but still doesn't make it so. I can call a Ford a Chevy also, but it doesn't make it so. Matt |

"white gas" in the South (at least) since I was born (also at least). It's called that because it's clear. I remember when I was a kid that you could go to some gas stations and buy "white gas" from a tank in the back room (with a handcrank pump). We used it in a Coleman stove. Then we found out that Amoco premium unleaded could be used as well, so we used it thereafter (easier to find - dunno if it was cheaper or not). This was in the '50s in Ohio. BTW I still have that same Coleman stove, and it still works. I have heard that you can store avgas for extended periods - and I have a way of finding out. I have a trail bike that has been in storage for a long time (over 10 years). I always ran it on avgas, and it still has some in the tank. When I can find a battery for it I'll try starting it and let you know what happens (was planning to get it going again anyway). David Johnson |

the fuel system? BRBR According to Chevron, a year or more should be no problem for avgas. -- Dr. Nuketopia Sorry, no e-Mail. Spam forgeries have resulted in thousands of faked bounces to my address. |
