shelf life for 2 stroke oil?

I had a customer give me an unopened gallon of 2 stroke oil today because he was cleaning his basement out getting ready to move. I asked how old it was and he said a couple of years old, so I took it to be polite, but I don't think I'm gonna take a chance on using this oil. This stuff doesn't last forever, right?

Not completely sure about this one...what brand of oil is it? I wouldnt run it myself even if it were a decent brand due to the fact that I wont risk ruining 1000's of dollars in equipment by saving pennies on oils.

Maybe 15 years ago Pennzoil 2 cycle was bad about getting lumpy and seperating out. That was the old TCWII oil. I saw a few boat engines bite the dust because of that. If you have a clean and empty gallon jug, transfer it to the clean jug and watch as you pour it, if it isnt lumpy I think it would be ok. What brand is it by the way? It may be a water cooled 2 cycle oil for a boat

the brand is tech 2000 oil, which I've never heard of it before. Would water cooled vs. air cooled engines make a difference? My friends and I used to share 2 stroke gas for our dirt bikes and one guy had an older bike that was air cooled and he used our gas and never had a problem that I knew of. Didn't even think about that.

I wouldn't risk it! Being polite is one thing...putting your business on the line is another.

Yeah, I was weary about it from the start, but figured I'd ask. I'll just drop it off at a garage to let them to dispose of it.

First off, I agree with you as far as running some 'other' oil, if you're not sure and you have to ask, then don't use it.

Secondly, I really kinda dread it the moment a customer thinks they have something great to give me, LOL, thou I must admit I did get a cool Honda riding lawn-mower once which I fixed back up and sold for 300 dollars :) Most the time, thou, it makes me feel like Sanford & Son, heh.

Now for shelf life, I use Stihl 2-cycle mix for ALL my 2-cyclers and I buy it by the flat, which is 48 bottles at a time, makes 120 gallons. As things stand, a flat of 48 bottles lasts me close to 3 years and the last bottle is as good as the first. Same with motor oil, I have close to 100 quarts stored because I buy my oil in quantity... It's all various grades and again I have 2-3 years worth, maybe more - The trick is to keep proper rotation (oldest gets used first) AND to make sure the oil bottles stay sealed, in a cool environment and out of direct sunlight IF the bottle has transparency to it.
Other than that, shelf-life wise...I don't see 5 years storage hurting a thing but again, if in doubt as to the quality, don't use it. Too bad it's 2-cycle mix, sometimes with standard motor oil when I'm not sure about the quality, all straight 30-weight AND 20w-50 oils make an excellent chainsaw lubricant :)
Also I've had my hand on some 'other' 2-cycle oil myself and I wasn't sure so what I did is I mixed it 10% other to 90% Stihl oil but then I only had a quart of it to dilute and still it took me the better part of 30 minutes to spread it all out and find the empty bottles, etc, etc...

Dump it on your trailer floor and mop it in. That's what I do with used oil that I get when I change oil in something. Cheap sealer. :p

tech 2000 is from wal-mart -its low quality oil -fouls plugs etc . i wouldnt use it either. i tried some once-it sucked
Agree... Tech 2000 will ruin your equipment when it's new let alone after sitting in a basement for who knows how long.

My brother had to have the fuel system and carb on his boat motor replaced after using that junk.
