Just put this stuff in my car. Seems like a winner. There is only one UOA report of it, and it did shear to 60 as per the UOA. It starts out at 12 Cst., so it seems like it ends up after shearing as a regular 5w-30 starts out. I'd rather it shear to 60 than like 55-56 that a lot of dino 5w-30s end up. Also did the infamous freezer test and it looks to surpass regular pennz 10w-30, even though it has a 6 degree warmer pour point (-27 for HM compared to -33 for regular 10w-30).
