oil in the rear differential
Best regards to all
Please, can someone explain to me what the difference is between;
75W-90 GL-5
and
75W-140 GL-5
for example:
Gear 300 LS 75W-90 - Motul
and
Gear Competition 75W-140 - Motul
Hypoid axle oil G3
Part number: 83222413512
SAE 70W-80 GL-5 is provided for my Bmw, do I gain or lose something with 75W-140 gl-5?
Somewhere it is listed as a possible option to put and 75W-140 so I ask!
Thanks to everyone for the answers in advance
