Schaeffer's # 158 Moly Pure Synthetic Comp. Oil ISO 46 VOA. Line #3 on test is this virgin oil sample. It did not run for 1 hour as stated on test, they do not have a "0" hour setting.

Keep this post, it has the right JPG.
^I am not super experienced with UOA/VOA, but I agree.
I have never seen an oil without a healthy dose of Zinc at least, even when the oil has a lot of Molybdenum.

Look at the Atlas Copco $520 for 5 gallon oil in my other post. See what line 3 has on that virgin sample. This is flooded/injected rotary screw air compressor oil. This oil is $170 for 5 gallons.

In fact, many manf. are now specing very low zinc or no zinc levels in their hydraulic oils.
Newer additive chemistry's take care of detergency and dispersancy.
