Preventing stale gas

Post by DJ » Mon Aug 19, 2013 7:02 pm

What do you guys with multiple vehicles do to keep the gas fresh in the tank,or for guys with seldom driven vehicles? Mr Dover ,with 7 turnkey vehicles ,what do you do? Would be a lot of miles driving to use enough gas to keep them all from getting stale gas. What are ya all doin???

Thanks DJ

Stabil seemed to have worked most of the time. I used Sea Foam this past winter, Nov-March, the fuel did not turn slime green.

It's also a crap shot which to use with the alcohol in it.

Hmm. Maybe you don't have "Sta-bil" in Europe. It is a fuel stabilizing compound in liquid form that is added to the tank when you expect the vehicle/equipment to be idle for awhile. Here, in the US, it is a common product found in hardware, auto, and big box stores that sell tools, mowers and the like. It works very well. Add it to the tank in the fall (for mowers and gas-powered equipment), and no worries.....even if you don't move it until next spring. Excellent for our Jeeps, too!

Amsoil makes a fuel additive for ethanol fuels to prevent damage and storage problems, if you have access to Amsoil stuff ask about it.

I tried Seafoam this past storage season, it seemed OK, Stabil did not work in my MB the year before, the fuel started to turn to slime, and thanks for the AMSOIL tip, it's worth a try.

I'm in the fuel business. Modern fuels will react more readily with oxygen. This property makes them burn (oxidize) more completely, leaving fewer unburned or partially burned particles. The best thing you can do is store you vehicle with as full of a tank as you can get. The less space at the top of the tank, the less oxygen for the fuel to react with.

So a collapsing bladder type of storage container would be ideal for gasoline right? I gotta work on that.

And DJ, I realize this is in response to a 5 year old post, but I have become a believer and user of LUCAS Upper Cylinder Lubricant, it is a gasoline additive for both Gasoline and Diesel fueled engines. The results are positive and noticeable. I try to use Irving Fuel or Exxon/Mobil and have had some sick running engines during spring start up. This additive has positive effects. I used to pile the mileage on CJ 5 4CYl and my M-38A1's, they were my Cadillacs and were fun to drive. They sit a lot now and although in top shape, they need a little "Geritol". :wink:

Before Sta-bil got it's act together for ethanol, there was blue colored STARTRON which was sold at Walmart and boat shops. This has been my go to mix in the Winter, but really starting the vehicles every two weeks is almost a must, especially the M151's finicky carburetor which gums up easily.
Went away a year to Afghanistan, my WC Zenith carbs fuel pump locked in place so tight it broke off when I returned. Have left the GPW to sit for 4 months and she gummed up enough to lock the carb passage shut until I used some ether to start her which created enough vacuum to pull fuel finally.I think any of the blue colored treatments are what you need for longer term storage, not the red stuff.

With the high alcohol content of ethanol gas you want a stabilizer without alcohol.
Startron enzyme or amber colored marine grade sta- bill without alcohol.
