After doing a bit of reading and debating between Royal Purple, Mobil 1, and Amsoil synthetics, I have decided on taking a step toward a fully synthetic car by using Royal Purple in my differentials and Transfer Case.
Amsoil seems to be what everyone on here is shooting for, but their marketing is obviously sub-par in the fact that the only way to buy their goods is online, and it is a shame that they don't widely distribute their product. Even BP gas stations don't carry Amsoil lubes, despite the fact that BP is an Amsoil company.
Royal Purple Products have several independant studies with dyno testing proving their efficiency, and it is pretty hard to argue with that. Not to mention, several local stores appear to carry everything I need. I am worried that local level stores might not carry their gear lube, but I will find out tomorrow.
Mobil 1 seems to have nothing but good reviews, and if I can't get all the Royal Purple products I want I will probably end up using Mobil.
My main question for this post is, what weights have all of you used in your transfer case, differentials, and transmission, and what kind of results have you guys seen with Royal Purple? Do you think 2-3 quarts of 75W-90 will cut it for each differential?
