Pennzoil Long-Life Extended Warranty SAE 75W-90 and 80W-140 Gear Oils have received approval for 500,000-mile extended drain intervals for ArvinMeritor (formerly Rockwell) heavy-duty, over-the-road truck axles equipped with pump and filter systems.
With the approval, fleets and independents may now use the Pennzoil lubricants for both service-fill and factory-fill at the same change interval specified for approved synthetic fluids, and still qualify for ArvinMeritor’s 750,000-mile extended warranty coverage.
