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 heavy-duty, over-the-road truck axles equipped with pump and filter systems.
Fleets and independent truck operators may 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.
The approval also brings with it a new ArvinMeritor specification — 076-Q Extended Drain Hypoid Lubricants — that outlines features and performance requirements of field-tested, extended-drain axle fluids made from Group II base oils.
