Product Number: 75032E
BG Ultra-Guard® Full Synthetic Gear Lubricant (75032E, 946ml) is an API GL-5 rated full synthetic gear oil blended to SAE 75W-90 viscosity for excellent on-road, off-road and marine lubrication applications. API GL-5 is the highest commonly used gear oil specification, suitable for hypoid axle gears operating under the severe shock, high-speed and low-speed/high-torque conditions of modern differentials.
BG Ultra-Guard® provides extreme-pressure (EP) protection to prevent gear tooth wear and scuffing in differentials and axles. Its full synthetic base provides superior thermal stability and oxidation resistance compared to conventional gear oils, extending service life and maintaining protection between changes. Excellent low-temperature fluidity ensures reliable gear lubrication from cold starts.
Suitable for differentials, axles and manual gearboxes specifying API GL-5 SAE 75W-90 gear lubricant, including on-road, off-road and marine applications.
Add to transmission fluid at the recommended dose. Suitable for use in passenger cars and light commercial vehicles — always follow the vehicle manufacturer's transmission fluid service recommendations.

A. BG Ultra-Guard is a full-synthetic API GL-5 gear lubricant blended to SAE 75W-90 viscosity. Provides protection for driveline components — maintains system cleanliness, thermal stability, seal performance, quieter operation, and protection against wear, pitting and corrosion.
A. For driveline use including on-road, off-road and marine applications where an API GL-5 SAE 75W-90 gear lubricant is specified. Suitable for hypoid differentials, axles, and transfer cases requiring GL-5.
A. Follow the equipment manufacturer's service recommendations for fill quantity and service interval. Keep the gearbox topped up to specification. For limited-slip applications, add BG Universal MGC (PN 328) at a 10% treat ratio.
A. Yes — but the LSD requires the addition of BG Universal MGC (PN 328) at a 10% treat ratio for correct limited-slip friction characteristics. Without the MGC, the LSD will chatter.
A. GL-5 (BG Ultra-Guard, 75032E) has higher EP additive content for hypoid differentials and severe-duty applications. GL-4 (BG Syncro Shift II, 79032E) is for manual transmissions where excess EP additive can corrode synchros. Use the OEM-specified grade.
A. A 946ml bottle is a partial fill — most passenger-car differentials hold 1.5–2.5 litres. For a full differential service, multiple bottles or a workshop bulk pack is appropriate.
A. Standard UK mainland delivery is 3–5 working days.
