SUNOCO FULL SYNTHETIC 75W-90 GL-5 is a heavy-duty, extreme pressure gear lubricant which is recommended for hypoid and bevel gear sets used in most rear drive differentials.


SUNOCO FULL SYNTHETIC 75W-90 GL-5 provides exceptional wear protection and oxidation control. Its wide temperature rating allows it to circulate quickly and lubricate critical parts at cold-start, while high in-service temperatures under load are easily handled without thermal breakdown. SUNOCO FULL SYNTHETIC 75W-90 GL-5 is a long-life service product when compared to conventional counterparts.


SUNOCO FULL SYNTHETIC 75W-90 GL-5 is intended for service fill, top-off and refill of hypoid and other drive axles usually found on high performance rear drive and four-wheel drive vehicles, which recommend API GL-5 gear lubricants. Meets or exceeds the API GL-5 and MIL-PRF-2105D.
