Golden Spectro in 100LL at 40:1 (milling) or 50:1
As long as it is at least semi synthetic for air cooled engines with the top norms Jaso FD, Iso-L-EDG and API Tc, I don't really care about the brandname.

I have a drum of 3o weight engine oil from Vietnam era, it's turned to about 90wt for some reason. I've been dumping 10 gals in my 300 gallon diesel tank when I get it filled.
I run the Lucas semi synthetic and dolmar full synthetic at 36:1. They are both cheap enough and high quality. Ran stihl ultra for a long time but the stuff gives me a headache and is no better than the two I use now and they are a good amount cheaper. Also use some Klotz original super techniplate once in a while.
Ya got me... but I haven't had issues with oil 5+ yrs old. Then again, I usually don't buy that much oil to sit around that long. However oil is relatively cheap, in the scheme of things... so I'd have no reservations pitching it either.
I got a bunch of different part bottles of oil and was thining of doing the same. They been layon around for years. Back when i just had a couple poulans i baught whatever.I use em all. All at once as I just keep dumping little bottles of whatever I can come up with cheap into my gallon mix oil jugs. Mix that "special blend" at 32:1 year after year.
