How old does gas have to be to be considered "old" and should not be used? i.e weeks, months? I have a couple gallons of 87 oct. gas that I have had since mid December, would that be considered old? How would I dispose of it if I had to?
Thanks

Probably about 3 months. You can use Stabil in new gas to prolong it's storage life. If this is for a lawn product, then consider using 89 octane.

As long as it shows no decomposition signs, you might be able to use say 0.5 gal of it in a full tank of gas in your vehicle. You can check where waste oil is disposed, otherwise use the Hazardous waste collection sites.

The small engine reps are now saying fuel is stale at the age of 30 days.

Gas that is over 30 days old is considered old -- If a gas station does not sell

Much gas it could be a month old when you get it -- so use fresh gas and run

It dry or dump it and burn it in your vehicle...

I have been having problems getting a Ryobi leaf blower to run -- but I found

The magic way to get it running -- Sea Foam is like a carberator cleaner

I put some in a squirt bottle and put a little in the gas tank and a couple squirts

In the carb intake... Really think this is a fantastic product -- TRY IT!
