Sleeve bearing motors - AW or R&O oil..Which is better?

Read our primer articles on Oil Analysis and Tribology

Our boiler feed water pump motors use an ISO 68 oil. Which is better for sleeve bearings, a AW type or an R&O? The motor is indoors in a climate controlled bldg. Thanks for your advice.

R&O is preferred. AW additives can have reactions with certain metals especially at elevated temperatures. Shouldn't need AW in sleeve bearings.
