Gl-4 Vs Gl-5 - Yotatech Forums from www.yotatech.com
Gl5 gear oil is a lubricant with very high extreme pressure performance needed for hypoid gears where sliding and rolling contacts operate under very high loadings. This is achieved by incorporating high concentration of sulfurized additives. Gear oils all include some level of sulfur or phosphorous additive.

Hypoid gears generate much more pressure between the gear teeth than other gear designs. Gl5 differences the main difference between gl4 and gl5 is that the former has more additives to boost its extreme pressure.
