Tutela Transmission B-5X
Fully synthetic EP 75W-90 oil for PTUs and non-limited-slip rear axles of 4WD cars
API GL-5
PETRONAS Tutela Compaq Drive 75W-90 is a fully synthetic final drive lubricant with Extreme Pressure (E.P.) characteristics, delivering optimised performance and component durability for rear axles with limited slip differentials using carbon friction plates. It is designed for the rear axle of 4WD vehicles operating under severe conditions. The optimised friction properties help reduce limited slip differential noise, while high performance at low temperature together with high oxidation resistance result in cleaner components and extended component life, making it suitable for use in a wide temperature range. Specifications: API GL-5. Approvals: FIAT 9.55550-DA7 Contractual Technical Reference N° F007.B14. Always consult the owner’s manual to check the recommended viscosity grade and specification for your vehicle.
