I have 11 restored collector cars. Right now, 2 of them are in museums, on two year loans. I've been seriously down the storage road. When I put a car away. Or the GMC. I generally don't know when I'll have that car out again. The GMC goes out every year. Love that coach. It seem to me that temp changes have serious affect on gas. My GMC, and cars are stored in heated, and air conditioned storage, with no light. The tanks that have unleaded fuel in them. Seem to do well for 12 to 18 months with no additives added. The Yenko Stingers that I road race at road courses. Have 12.5 to 1 compression. That requires 110 octane leaded fuel. That fuel seems to hold up for about 24 months. I understand that the gas additives that are used to extend the life of gas. Have a shelf life of their own. I DO NOT know this for sure what that is. When I put anything away. I like to have just a few gallons in the tank. This way if the gas in the tank is getting bad. I have room in the tank to a
dd fresh gas so I can bring some life to the old gas. As I see it. If the tank is full. What am I going to do with all that old dead gas. And I can't dilute it with fresh gas, as there is no more room in the tank. Can be a lot of money down the tube. Plus I end up with less mass to attract condensation in and on the tank. Put two containers in the frig. One with a little liquid in it. One with a lot. The full one will attract the most condensation when you put both on the counter top.As far as starting your engine every two weeks. Look at it this way. Every time you start the engine. You fill the carb float bowl with fuel. The next time you start it. You fill it again, as the fuel that was in there has evaporated from the last start up. Each time there is a residue left from the time before. This builds up over time.When I put the GMC, or cars away for a length of time. I change the oil and filter. Start it up to get the fresh, clean oil in the lifters, and bearings. then
take it for a 10 mile drive. Shut it off. Disconnect the battery, and put a battery maintainer on it. An then leave it alone.To start it up after some time. I put 5 gallons of fresh gas in the tank. Take a small squeeze bottle with fresh gas. Fill the float bowl by putting the fresh gas down the float bowl vent. Start the engine. I keep the float bowl full from the bottle as it's running, for about 5 mins. This allows the engine some time to get some warmth in it. Then I start to back off on the bottle. This then starts to get the old fuel that is in the fuel lines, and pump to blend with the fresh in the float bowl. I have never had any problems with any engine starting after storage. And I'm not cleaning my carb out all the time. Bob Dunahugh
