Maintenance and Replacement Even the highest quality GL-5 will degrade over time due to heat contamination and the breakdown of additives. This layer prevents metal-to-metal contact during the heavy loads and shock forces experienced during acceleration or when climbing steep grades.
GL-5 Gear Oil Temperature Stability and Performance Under Heat
However, using a GL-5 in a manual transmission not designed for it can sometimes lead to issues with synchro wear, as the aggressive additives can interfere with clutch friction material. These components often utilize hypoid gears, which operate at high sliding velocities and require the extreme pressure additives found in GL-5.
The robust additive package significantly extends the life of the gear sets and bearings by minimizing microscopic surface damage. Viscosity and Temperature Management The viscosity of the oil determines its ability to flow and create a film between moving parts.
GL-5 Gear Oil Temperature Stability and Performance Under Heat
Most manufacturers recommend a complete fluid change every 25,000 to 50,000 miles, though this varies based on driving conditions. Regular maintenance is essential to prevent the accumulation of metallic debris and worn particles.
