API GL-4 gear oil is made for gear sets that operate under various conditions, from light to heavy. Designed for many synchronised gearboxes, as well as some transfer cases and differentials, it provides dependable lubrication and protection for both everyday use and more demanding applications.

These oils are particularly recommended for synchronised gearboxes found in lorries, tractors, and buses, where ample protection is especially important under heavy loads. API GL-4 gear oils are also the standard choice for many synchronised gearboxes in cars and light commercial vehicles, giving good performance in a wide range of operating conditions.

At Opie Oils, we stock a variety of API GL-4 oil from trusted brands, such as Millers Oils, Castrol, and Motul, all chosen for their consistent quality and performance. From 75w80 API GL-4 to 10w30 and SAE 90, we have options to suit a wide range of vehicles here.
