Some manufacturers recommend changing the factory-fill gear lube within the first 500 to 3,000 miles based on SAE test stand and field tests. AMSOIL recommends the factory-fill differential gear lube be changed no later than the first 5,000 miles, even when vehicle manufacturers do not specify to change the factory-fill gear lube to remove wear particles.

When using AMSOIL synthetic gear lubes, AMSOIL recommends drain intervals of 50,000 miles in severe service or 100, 000 miles in normal service, or longer if stated by the OEM. AMSOIL synthetic gear lubes not only offer second-to-none protection and performance in cars and light trucks, including turbo diesel pickup trucks, they are much less expensive than OEM synthetic gear lubes. Changing break-in wear particles out after the first 5,000 miles of service and using AMSOIL synthetic gear lubes at the correct recommended gear lube drain interval ensures long, trouble-free differential life.
