I know this has been answered before but I can't find it in the older posts. What is the best Vac Pump oil to use in a SP22?? Thanks Mike

I have experimented with a couple different oil and oil concoctions. Best I have used is the vacuum pump oil sold by tractor supply. Pump runs cool and very little mist.
