API GL-4 Gear Oil

API GL-4 oils are for various conditions - light to heavy. Designed for bevel and hypoid gears which have small displacement of axes, and axle units. Recommended for non-synchronized gearboxes of lorries, tractors and buses and for main and other gears of all vehicles. These oils are basic for synchronized gearboxes.

You'll find what specification gear oil your vehicle requires in your handbook, if you're still not sure, contact the Opie Experts for a custom recommendation.
