 rear end lube
greetings, quick question, i posted a message about this before but i just have a quick question. i was looking for synthetic gear lube, and i found some, its 75 - 90. is that what i want? my father has 80-90 mystik regulaur gear lube too. will that work? what should i look for when buying synthetic lube? or is it pretty much universal. and how much fluid is needed when u fully drain the diff. to fill it? thanks.
