I was going from the top of the chart where it stated 75W90 (and 80W90) GL-3 applications cross to the HPS/XPR, and that GL-4 or 5s would be the MaxGear. The owner's manual for my FR-S specs a GL-3 fluid. I saw that and didn't even look at the product advisor. I'm temped to call, and see what kind of reaction I get when I point out the GL-3...they'd probably think I'm an a-hole, but I genuinely curious.

I didn't know that mm2/s Cst's were the same...should join up over at BITOG, but I spend too much time here.

Thanks for the link.
