Redline MT 75W90 is proving very difficult to find locally.
I found some Royal Purple 75W90 that claims it is fully compatible with both GL-4 and GL-5 standards and will not corrode brass parts.
Are there any other GL-4 options that won't require a specialty order for the differentials, transmission, and whatever goes in the transfer case?
