Has anybody used the Royal Purple 75w90 Max-Gear fluid for their Rear Differential? I saw it today and was suprised that nobody has recomended it online.

Because that company is all about marketing and not about engineering. Run from RP.

 

Most likely the reason being is RP isn't that great of a product.

but but but GI joe is using RP

m1 for street and amsoil for race/heavy duty

 

What is your logic for this decision.

but that isn't an independent study, Amsoil put that out so of course they're going to say they're the best

and I do agree with the deadhorse, everyone has their opinions on auto fluids. This topic is covered repeatedly on every car forum I've been on.

 

I'm using it. I've been daily driving mine for about the last 15,000. I plan on swapping to LE1605 soon though. No problems yet and my diff has 145k on it.
