Urania Prime Classic 10W
Monograde engine oil for older commercial vehicles, also suitable for CAT TO-2 systems
SAE 10W
PETRONAS Urania Prime Classic 40 is a monograde heavy-duty diesel engine oil formulated for older commercial vehicle applications and high-revolution turbocharged diesel engines, on-highway and off-highway, where API CF is recommended, helping to control wear and corrosion. It is also suitable for use in transmissions, differentials or final drives in equipment where API CF (or lower) SAE 40 engine oil is required. Urania Prime Classic 40 replaces Urania 500 SAE 40. It supports piston cleanliness and minimizes deposit build-up, helps disperse soot to reduce soot-induced oil thickening, and offers good TBN retention that effectively neutralizes acidic combustion by-products. Urania Prime Classic 40 meets API CF.
