Extended Drain Axle Lube
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, truck operators 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 the ArvinMeritor 750,000-mile extended warranty coverage.
The approval is in line with a new ArvinMeritor specification that outlines the features and performance requirements of field-tested, extended-drain axle fluids made from Group II base oils. Pennzoil claims it is the first and only gear lubricant supplier to be approved under this new specification.
Introduced last year, the Pennzoil Extended Warranty gear lubricants have extended drain approval for use in Dana heavy duty drive axles, as well as in Mack truck axles and manual transmissions.
Mineral-based Pennzoil lubricants offer protection equivalent to that provided by extended-drain synthetic-based gear lubricants, says the company. The products also are compatible with synthetic lubricants, thereby allowing for convenient top-offs and refills without flushing.
