I think people are starting to realize why I almost always recommend 75W-110 in SAE 90 applications - I mean for nothing more than any application calling for SAE 90 is very likely old revision SAE J306, and by using NEW 75W-90, they are only using the lower viscosity end of the 90 range, so to speak. By using 75W-110, then you have a 100° fluid in the 18.5-24 cSt range, but still have decent cold weather performance.
