Is 2 year old gasoline any good ?

[ACUDANUT]

How can you tell ?

Is it stinky? I don't trust stale fuel after cleaning my 6BBL's bowls out anymore. 

[ACUDANUT]

I really lost my sense of smell. I wish there was a gauge/devise made that tells you it's ok or bad.  Any inventers out there ?

Here's a tester.

Ethanol? Heck no. Non-ethanol? Good chance it's fine.

The higher compression you have, the less tolerant the engine is to old gasoline. A lawnmower with 7 to 1 squeeze may be fine with it.

What grade of gas?  Racing fuel = not a chance (at least I wouldn't risk it...)

[daveco]

The cost of finding out (with any degree of certainty) is more than the gas is worth.
When in doubt, throw it out. (or feed it to your lawn mower)

  nope would not use it  ,    use it  for  cleaning  parts

You know how certain smells bring back memories? The smell of stanky old turpentine gasoline reminds me of my early days going to junkyards before they started draining the tanks. Old cars had that specific smell.

  How much fuel do you have? After my car's "big sleep" in storage I ended up with 12 gallons. (Much older than 2 years.) All turned in at the county HAZMAT, their tanks were full so I ended up donating 2 x 5 and one 2 1/2 gallon containers. I eliminate unknowns regardless of loss. As my body/paint repairs dragged out my fuel went stale in less than a year but I had about 6-7 gallons in the Chargers tank and FL. has very high humidity. That fuel was drained and slowly mixed with fresh in my Jeep at 5 fresh to 1 stale. (No problem for an 89 Cherokee system.)

 yea, I will just burn it up. I live on a Farm.

I have a standby generator that rarely gets run more than once a year and the gas in it is years old...starts on the 2nd-3rd pull every time.

[Kern Dog]

Even one from Harbor Freight?

I have an old rotor tiller that is run 20 minutes a year. Same gas been in it for 5 years. I know it's a gamble every year but it runs so dang good.

will fire up without problem... better or worse, but still will fire up, and actually won't hurt anything at least for a regular driving

[ACUDANUT]

 I will get another of sniffers (nose) and go from there.
