Hmmm... I only see viscosity loss results for 5 of the oils tested? Though they even mention, viscosity loss is not expected in such a short test.

An oil with "middle-to-fair wear particle rating" is one you'd choose, not good or excellent?

Also of note: AMSOIL is rated #1; coincidentally, the website is an authorized AMSOIL dealer!

Low viscosity oils are used for increased H.P. and fuel economy ( reduced friction ) , not for increased engine protection. The site states ( concerning 0 wt. oils ), "for regular street-driven engines, it would be better to look at an oil with a good service interval". Check the descriptions given by any supplier of racing oils, they call 20 wt. oils "qualifying oils", and recommend 30-50 wt. for longer races.
