GL-4 vs. GL-5? | BobIsTheOilGuy
2002年11月29日 · Mobil says that their GL-5 is good in all applications EXCEPT manual transmissions that call for GL-4 only. Oddly, they both told me that their GL-5 supersedes the GL-4.

GL4 vs GL5 gear oil - Maintenance/Repairs - Car Talk Community

2018年6月21日 · Could this be as simply as buying any 80W-90 GL-5 (like Sam's club) in a 5 gallon bucket and adding 4 oz of LSD additive to the rear axle only?

GL4, GL5, GL6, what's the difference? | BobIsTheOilGuy
2002年6月5日 · GL-4 oils, when recommended are usually recommended for the transmission, where torque is much lower than in the differential, where the final gearing takes place - therefore the need for more protection of the GL-5/GL-6.
