Inaccurate performance data for BOB fighters in COD comparing to RL data

What was the storage life for the fuel,

Don't confuse the sweetened stock with the blended fuel you put in your tank. Blending does not occur until the gas is leaving the storage facility and heading for the pump to be sold or put into a vehicle to be used. Once it is blended, it is considered consumed.

All the 100LL stock is made one time per year. It is not blended though until it is sold to an airport. The Reid Vapor Pressure tolerances of aviation fuel are much more stringent than automotive fuel.

The Energy Information Administration says the switch between the two fuels happens twice a year, once in the fall (winter blend) and again in the spring (summer blend). Summer-blend gasoline is typically more expensive to produce than the winter blend, and it won’t affect vehicle performance or the durability of the engine and fuel system, according to the EPA.

You can get away with blending automotive fuel twice per year for the most part.

Airplane fuel does not work that way. My old Socata used to have vapor lock issues because I did not fly for months when I was away on business. The plane would sit with full tanks in the hanger. By the time I got to fly it, the conditions had changed from when it blended to maintain Reid VP and I would end up hitting the auxiliary fuel pump all the time to keep my fuel pressure up so the engine would not quit. Once that gas was out of my tanks, I did not have to use the aux pump except for start, takeoff, and landing.
