This is a bummer. It seem these new gasoline supplies we use won't last too long in storage. After a month it'll gum up your car engine.

$this->bbcode_second_pass_quote('', ' ')The problem begins with today's modern fuels. These so-called "clean" fuels typically deteriorate at much faster rates than fuels made 20 years ago. While all fuels suffer from the problem, most at risk are the EPA mandated reformulated gasolines (RFG) that contain oxygenate additives, derivatives of methyl alcohol and ethyl alcohol. We've seen gasoline have shelf life as little as a month--particularly if it is subjected to heat and moisture.

Diesel fuels fare a little better, but not much. Most all diesel fuel, including the EPA's mandated low sulfur version, has shelf life of from 3-to-6 months. Again, this varies widely. Recently we tracked a diesel fuel produced at a refinery in Texas to its final destination in Florida. When tested at the refinery the same day it was produced, the fuel barely met the specification for stability. After being stored, pumped into a coastal tanker, offloaded at Port Everglades, stored again, delivered to the fuel jobber, and finally to the customer, 23 days had passed. Again the fuel was tested. This "fresh" fuel now tested out of "spec."

Sounds like BS FUD to me - trying to prevent hoarding maybe? I have stored so called "oxygenated" gasoline for over a year and ran it without any problems.

The article was written by a guy who works for Power Research Inc. They sell stuff to keep gas "fresh." So maybe you're right, gandalf. I just want to know the facts, not BS.

BS, keep gas in jeep cans, filled full and tightly sealed, it will stay good for years.

P, I think this thread has been done a couple of times in the past few years. Some hardcores will tell you they have gasoline from WWII and is still good if you just pump in some Stabil or whatever. Others will tell you it's only useable for a few months. I don't know what to believe because I don't have the balls to ruin most of my stuff with 6 month old gasoline, although I usually use gas that old to run the lawnmower.

I met a scrap dealer a few years back. He would take all the old gasoline that came out of junkyard gas tanks prior to the car being crushed and hammer milled (shredded) and pour the horrible fluid into buckets to settle out. Water to the top to be skimmed off, sediment and varnish and horrible murky smudge to the very bottom to be excluded when the bulk was poured off into the reclaim tank. This would be run off though a fuel filter into his big block, carb V8, Detroit pickup, and he would never use more than a 50% ration of this witch's brew and brand new gasoline. He said he had given up on trying to do anything similar on fuel inject vehicles after terrible results on multiple vehicles.

As AlCzervik said, this would be safe only for a lawnmower with a simple carb engine. I have smelled veggie oil fueled diesels that smell like french fries or Chinese food, but this truck smelled like he smeared sugar on old furntiture and set it on fire. He could have hung up a taco on the rear view mirror as an air freshener.

Storing some jerry cans for two years and then road testing would be a great idea for the Mythbusters show. It might keep a bunch of folks from saving high flash point fuel with huge liabilities and what I suspect would be poor results.

Follow up to my post, water and darkish matter to the BOTTOM, some other funk floated on top and was skimmed off, who knows what. I was actually waiting on him to finish and fire up a bobcat to load my el cheapo surplus steel fence posts I bought. Still, if someone has stored plain old gasoline in a clean container for several years, and then had good results, please chime in.

I have used 2plus year old gasoline, in a 1979 Ford 300 cu 6 cylinder. No ill effects, and not blended. Don't ever try this in a fuel injected engine. I only ran one tank, don't know if it would eat this day after day. You might be cleaning your spark plugs every couple of days or have to regap them, to get better ignition. Should not be a huge problem on older, low compression standard type motors. The early tractors ie Oil Rumley's had a carburettor that mixed gasoline, kerosene and water. I father in the 1930's ran his old Ford, on straight kerosene. Start the engine up on gasoline, switch to kerosene, do your drive then switch back to kerosene before you shut off the engine. The old Fords had an adjustable magneto, spark control right on the steering wheel.

I meant to say switch back to gasoline, before shutting down the engine. Here is a link to that carburettor. http://rumely.rustyiron.com/secor.html
