Multipurpose R&O Oil

Rust & Oxidation-Inhibited, Antiwear Circulating Oil

Phillips 66®Multipurpose R&O Oil is a rust and oxidation (R&O)-inhibited, antiwear circulating oil developed for use in circulation systems, centrifugal air compressors, geared turbines, lightly loaded enclosed gear drives and many other industrial applications. It contains a low level of ashless (zinc-free) antiwear additive for mild wear protection.

Features & Benefits

• Good oxidation resistance to minimize sludge and varnish formation

• Mild wear protection

• Protects against rust and corrosion

• Excellent water-separating properties

• Low carbon-forming tendency for use in centrifugal air compressors

• Good foam resistance


• Air tools and other pneumatic equipment lubricated through air line lubricators

• Centrifugal air compressors

• Steam turbines and hydroelectric turbines, both direct-drive and with gear drives

• Lightly loaded enclosed industrial gear drives where the OEM specifies a R&O type oil (ISO VG 68 and higher, typically)

• Lightly loaded plain and rolling-element bearings, such as those in electric motors and blowers

• Vacuum pumps, deep-well water pumps and machine tools

• General-purpose machinery and shop lubrication
