When to Use / Replace?

Use in light to medium-duty diesels for daily hauling or regional routes. Replace every 10,000-20,000 km (6,000-12,000 miles) or 6-12 months, or sooner for severe use like towing or off-road (every 5,000-7,500 miles). Always check your vehicle's oil life monitor or manual first.
