Gulf Western Low Vis Gear Lube 75W-90 is a high performance gear oil for modern manual transmissions. Low Vis Gear Lube 75W-90 is also recommended when SAE 75W or 80W are specified.

It has the balance of viscosity and frictional properties, which ensure good shift feel and fast gear changes. This oil is ideal for modern 4 and 5 speed manual gearboxes which need low viscosity oil for cold changing yet still need an SAE 90 when warm, to ensure quiet running.
