That's a good question. A friend claimed it could last more than five years. I think a year is no problem in most cases, but the more gas in the tank, the longer it will last. In a lawn mower it might go bad over winter. If you suspect the gas is bad, I have a test you can try. Either open a fuel line, or syphon out a little gas into a small metal jar lid. Move the lid outdoors to somewhere away from anything flammable. Keep a fire extinguisher or at least a garden hose handy. Then light the gas with a match or lighter. As you bring the flame toward the gas, the fire should jump fast to the gas. An audible "poof" is a good sign the gas is okay. If the gas is slow to light (like a candle) your gas is very weak. If you decide the gas is bad, you can drain the gas tank by sucking through the short syphoning pipe located on or near the fuel pump mounting flange. That pipe is usually capped with a hose-like plug.
they can stay good for about 4 weeks.
Vehicle repossessions stay on you credit report for 7 years.
Nothing can stay good if it never was.
A driver delivering gasoline must remain within 100 feet of the vehicle during the entire transfer operation. This safety requirement is set by the Department of Transportation to minimize the risk of fire and other hazards associated with gasoline transfer operations.
7 years after the account is settled.
Yes there are cosmetics that can stay on your face for a long time. Long Last by Cover Girl is really good. And Revelon Color Stay Liquid Foundation is good too.
Untreated gasoline starts to go bad after 30 days. Treat it with a fuel stabilizer and theoretically it will last one year. If you keep it that long I would mix the treated gas with 50% fresh gas when you use it. That 50/50 mix will be ok to use. Untreated gasoline over 60 days old mix with 80% fresh fuel before using.
It will stay good for years.
== == A minimum of 3 years and in some states as long as 10 years.
That's a pretty good indicator of their intent.
