The extreme pressure additives activate under high stress, preventing damage that standard oils cannot withstand. Conversely, using a GL-5 where it is not required offers no additional benefit and may affect the performance of certain friction clutches.
The GL-5 designation confirms its suitability for hypoid gears typically found in automotive differentials, especially those requiring extreme pressure protection. Understanding the specifications of heavy-duty lubricants is essential for maintaining peak performance in demanding mechanical applications.
