Most differential wear occurs during the first 5,000 mile break-in period. Because differentials are not equipped with filters, break-in metals are suspended in the oil, causing increased wear as the particles mesh between the gears. Hauling heavy loads and towing heavy trailers causes additional stress to the fluid during the break-in period and can lead to premature gear damage or failure. Some auto manufacturers actually recommend an initial drain interval of between 500 and 3,000 miles.
You can do yourself and your vehicle a service by changing to a high quality synthetic gear lube following the break-in period in order to reduce wear and extend differential life.

The Castle Gear Lube + meets all specs for OEM Warranties and has a built-in limited slip additive for extra protection.
