I've got some leftover premixed gasoline (89 oct) with Stihl 2-cycle oil in about 50:1 ratio. I don't know what to do with it. Is it a bad idea to use it up in a 4-cycle snowblower? I don't really want to dump it into my car's tank either.
2-stroke fuel mix bad for 4-stroke OPE?

^^This. Just use it up a little bit at a time, pour 1/2 gallon or even 1/4 gallon in your car with a full tank of gas. The car will never know the difference.
Or, if you do use it in the snowblower, just use a little bit at a time, like 1/4 tank 2-stroke mix (maximum) with 3/4 regular gas. The only thing I'd really be concerned with on the snowblower is fouling spark plugs. I doubt it would do much else damage-wise.

I run 50-1 in my lawnmower all the time. it doesnt make any blue exhaust and i have taken the head off to check things out. I did up the compression and run a slightly hotter spark plug. Just one heat range. I think if the oil burns off there would be no problems but if it ran cooler you could foul spark plugs or get a build up of carbon in the combustion chamber. Id rock it maybe not at a 50-1 but a 100-1 or 150-1 ratio for your machine.

I agree with the thin it out and run it.
About 1/4 gallon of it is all I've got. The reason I'm hesitant to put it in my car is that when I did this last year, I had elevated lead show up in my next UOA, however, the two may have been unrelated. I know some fuel system cleaners show up as increased lead on UOAs. Not sure if 2-cycle oil mix would have a similar effect...

My mower uses more than my trimmer and blower, so at the end of the year I just burn up the two-cycle mix in my mower.
At 50:1, I can't see it doing any harm.
Use it in the snowblower or the car.
You have only a quart or so of it?
Dump it in the car.
A quart of 50:1 mix in a full tank will end up as something like a 2500:1.
I can't see that causing any problems.

Totally unrelated.
1/4 gallon of premix contains less than an ounce of oil. Go ahead and dump it in your car. That minute amount of oil won't make a bit of difference when mixed with a few gallons of gas.

I often run two cycle mix in an old Tecumseh four cycle mower. I keep the mower up at the garage. If it runs out of fuel down at the lake, it will get 35:1 pre-mix that I keep down there for my chain saws. Been doing it for years. Never a problem. Mower doesn't know the difference.
It's OK to put in in your car, very diluted of course. It won't cause any problems, and it won't contaminate the cats.
Not a great idea to run it undiluted in the car though.
Interestingly enough, gasoline sometimes contains lubricity additives. AKA oil. 1 gal on 50 to 1, diluted with 10 gallons of gas is well within the "normal" spec for straight gasoline.
