Well I just found out that my '09 toyota comes stock with 75w-85 in the front and rear diffs. Toyota even issued a TSB for older yotas to start using the stuff. Does anyone have a PDS on this stuff? Who's making it? It's crazy expensive... Lists fore $31.28/liter. I can get it for $23.50/Litre through a discount yota house. That's borderline insane. Toyota states the reason for this lube is Fuel Economy. Maybe CAFE? I'd love to see a PDS on this stuff. I wonder if it's even GL-5 rated. Castrol's 75/85 is GL-4 only.
Other issue I have is they did not mention running it in the Transfercase. So the Tcase still takes 75w-90 or a 80-90. If you are on a all out MPG war with your truck I would probably fill the Tcase with it also right??
