I saw motorcycle chain lube as being a good lube for snowblower drive chains. Something that will not sling off at max. R.P.M. Tonight I tried chainsaw bar oil. After an hour of blowing I found an acceptable amount of lube on the chain. This was much better than the waterproof snowmobile grease I had been using and was a fraction of the price. I will have to apply every other time though. smoky
