I have a drum of oil with about 1/3 left. I bought it at a farm auction so it's some type of machine oil I would guess. The only markings on the drum say "Multiduty 3P" Pennzoil brand. It was sold through Purvis Bros locally here. Otherwise no marking for SAE type. I dumped some into a little jar and it has no odd smell like gear lube and no smell like motor oil. I'm looking for suggestions on how to figure out what it is. I analysis of it would work too I guess but it would be nice to avoid the expense of that if possible.
Thanks,
Steve
