Type of lube oil for SWG 4hds power venter?

Hello, do I really need to get the swg lube oil, or can I get away with 3 in 1 oil or 3 in 1 motor oil that says it can be used on 1/4 horse motors (20 SAE). I realize power venter is not a quarter horse but would it be okay?

Last time someone asked this question I think the answer was to use the special SWG oil because of the high temps.

Thanks snooze913, I guess that makes sense.

I asked that question a while ago,ordered a new motor from LL and Karen told me Mobil 1 fully synthetic 0w20 would be ok,oiled the old motor and stuck it back in the powerventer and it's still running,draft is slightly higher(.35, previous was .22) so I guess it's getting a few xtra rpms at the lowest setting on the rheostat. Mobil 1 has a blend says 5000 miles between changes,that is Not the one to get,the fully synthetic Mobil 1 says 15000 miles between changes,maybe a dollar more per quart than the blend(6.85),as opposed to 16 bucks an ounce for swg oil.I'll let youall know if it dies.

Ok, thanks bustedwing, how much did you put in motor, (drops wise)

About 6 per lube hole,ran it all last winter without lubing it because it was new and I assumed it was prelubed by manufacturer. RichB
