What's the Difference Between Gear Oil GL-5 And GL-4?

2019-10-23

GL-4 is a medium-load gear lubricant oil, GL-5 is a heavy-duty gear lubricant oil, so the previous truck oil change is the GL-5-85w90. Later, due to the poor working conditions of some engineering vehicles, with GL-5-85W140 grade Gear Oil, this gear oil has higher viscosity, better lubricity and high temperature resistance than ordinary gear oil, and then gradually popularized. Most of the gear oils of GL-5-85W140 are used.

GL-5 grade gear oil contains more sulfur than GL-4 grade oil, half more acid than GL-4 gear oil, acidic material will corrode metal, so the corrosion of GL-5 is much higher than the GL-4.

Since the gear load is generally above 490 MPa, and the hyperbolic tooth surface load is as high as 2942 MPa, in order to prevent the oil film from rupturing and causing tooth surface wear and abrasion, Antiwear Ep Additive are often added to the gear oil, and sulfur is commonly used. Phosphorus or sulfur-phosphorus-nitrogen Lubricant Additive.

In general, ordinary freight vehicles can be filled with more than 12 liters, 100,000 kilometers or a year of oil you can change the gear oil. Due to the low fuel quantity, it is recommended to replace the truck type of the light truck at 50,000-80,000 km.
