He stores it above ground and then uses through the year. According to this doc the shelf life is 1 year: http://amd.nbc.gov/akro/library/opm/AM%20OPM%2006-AR-20.pdf If you've got a place to store it go for it. Although with the dismal economy oil will probably stay put for a while.

In older fuel, loss of these components to any extent will adversely change the ignition properties of the fuel. Poor starts is one big symptom of old fuel (especially in colder climates). If you intend to keep the fuel for awhile first make sure it's fresh when you buy it and store it in an above ground tank with a floating roof. Store in a cool area out of the direct sun, if possible. The floating roof on the AST reduces volatilization of the light components. Also, if you're buying a large quantity from someone who uses a lot of 100LL anyway, ask them if you can buy a "position" in their tank. That way you'll be able to take your contracted amount out of a tank that is being turned over on a regular basis. In any event, I wouldn't recommend using fuel stored in any container that is open to the atmosphere for longer than a month or so (my opinion, no hard facts). You could also check with a local FBO or your supplier to see what they recommend.

Here are links to visit.

Auto gas should not be stored for more than six months. If you have a large tank=2C it should have a floating suction so that the fuel pumped out is clean and you do not disturb the sediment on the bottom of the tank. It is also important that a tank is allowed to settle after a delivery and prior to fueling. Ben Visser is an aviation fuels and lubricants expert who spent 33 years with Shell Oil.

For Charlie Cuss Charlie ... If you are 'listening' I have a car question. Do you, or anyone else, know if the timing belt for 2001 RX 300 Lexus, can be purchased from a regular Toyota dealer? Could there possibly be a cost savings through Toyota? Also, are the Goodyear belts just as good? The Lexus part number would be a plus to copy from anyone going there lately. Apologies to the List for the off topic. Thanks ...

Evaporation of components is extremely slow. It is blended with inherently stable components such as alkylates. A few folks made out very well draining fuel from stored WWII planes when they were scrapped, with fuel that had sat in the planes for more than a year, probably several years. Unless you are using the fuel in a turbocharged engine, the slight loss of octane is unlikely to have any impact. Likewise, with its low RVP avgas age has virtually nothing to do with starting properties of aircraft engines. Many planes in cold climates sit all winter, and have no problems with the gas in the spring. Evaporation isn't an issue for planes that sit all summer in the Arizona heat.
