I was checking the Mag1 site and looking at the HM specs and the have been thinned down. The 5w30 is down to 8.9 and the hths is 2.68. If the is is the same thing as Supertech All Mileage, it is thinner. Some have wondered if the new owners would change things and it might be they are.

It could be a mistake but again SP seems to have been a cause or contributor to thinner oils. If you look at the Mobil High Mileage 10w40 it's viscosity at op temp. is 12.9 that is getting to almost a 10w30.
