Using this grade ensures that the protective films are robust enough to prevent scoring and pitting under heavy loads, such as those experienced during towing or climbing steep inclines. Summary of Key Considerations.
Essential Safety Precautions When Using GL4 Gear Oil
Technical Composition and Performance Characteristics The defining feature of GL-4 lubricants is their carefully calibrated additive package, which includes anti-wear agents, rust inhibitors, and antioxidants. Many differentials require a specific fill method, such as filling until the fluid reaches the bottom of the filler hole orifice.
These formulations are designed to withstand the high sliding and rolling pressures generated between the non-parallel axes of hypoid gears. Crucially, GL-4 maintains a moderate level of Sulphur Phosphorous Content (SPC), providing robust protection without exhibiting the overly aggressive friction modifier profile of GL-5, which prevents potential damage to bronze synchros in manual transmissions.
