Most grease guns could hold 90 wt gear oil (recommended for normal usage) and pump that thru a grease nipple You could do the same with 160 wt if you want to use that. I've never seen 160 wt, but 75-140 gear oil is readily available. You'd have to be real careful about filling a grease gun (without cartridge) with gear oil to avoid making a huge mess. Most have a spring loaded plunger, and if that got away from you before you got the end screwed on -- eek
