Husband said 2 stroke oil for 10w30?

Hey guys, thanks in advanced for any and all help. I have an ancient boiler system in my home that feeds into the radiators which I’ve never lived with before. The tag on the boiler motor says to lubricate with either sae 20 or 10w30 every season but my husband says we can use 2-stroke oil? Is this okay to use in a pinch? Otherwise I’ve got a trip to Home Depot to make.....

    I have found that it is best to go with what is said in the manufacturers directions. A can of oil is easy enough to get so there should be no need to add a different oil "in a pinch"

    If you're referring to oiling the circulator pump, the SAE 20 NO DETERGENT oil should be used and it should only require a few drops. Over-oiling is the #1 cause of failure on those circulators.

    B&G has a specially formulated oil for that.

    Just as easy to get the right stuff. Looka round you don't need a whole quart. 3 in 1 motor oil is ok

    Husband may know something. Safest is to use high temperature oil for electric motors. And two stroke minimizes carbonization.
