Normally from my expirence, if gas has sat for 5 years or longer, it really is no good. I have bought trucks that have sat for years at a time and got them running. Often times, if the gas does not have water in it, I will put about 3 bottles of carb and injector cleaner in the tank and then once I run the old gas out, I will change the fuel filter and put fresh gas in it. I will also run the truck with a bottle or two of carb clean in the tank for a while just to make sure the fuel system gets cleaned out, and I change the fuel filter quite often. If I get a truck that has sat for longer than 5 years, I will normally drain the varnishy old gas out of it, and mix and run that stuff in something that either has low compression like a farm tractor or in a yard truck or derby car etc. Also you can mix the stuff with diesel fuel and run it out of a multi-fuel engine, such as what is used in the military 6X6 deuce and a halfs. \
If the gas has sat a really really long time and is very stale, its makes an effective camp fire starter as well. Fresh gas ignites too fast to be safe, but the really old nasty and watery gas ignites like diesel or Kerosene.
