I need straight 20 wt oil for my equipment.?

Question

Can I use 10w 30 for my Brown and Sharps screw machines? I am very leery of doing it having wrecked A VW 1600 by using a multi visc oil at -5 deg F.

Answer 1

I'd play it safe and go with 20W 40 if only mutigrades are available.
(Screw machines are assumed to be in a temp. controlled shop and run fairly slowly, so your concern is with 'base` viscosity).
