Amsoil is the First in Synthetics.
Amsoil was tested against the API back in 1972 and blew away the API standards. Amsoil has been the leaders in synthetic formulations for all sorts of industries.
Amsoil continues to be the Best oil in the World.
Amsoil products are continously tested against everyone else by independent labs all over the country.

Should you have further questions on the oil, the application, etc. Let me know.
I have been using Amsoil in everything I own since 1991.

I currently own a 2012 volvo xc70 T6 with 207k. I bought it about 18 months ago with under 150k on it.
Switched everything over to amsoil.
Did an engine flush, use the amsoil signature series (asl)5w-30. Change the oil filter out about every 7500 miles (mann unit). The oil changed out about every 24k miles.
Changed out the front axle, rear axle fluids to amsoil (svg)75w-90 signature series gear oil.
Changed out the transmission fluid to the Amsoil signature series (atl) product.

My car is currently averaging just under 27 mpg for fuel economy.

Reduce the heat, reduce the friction, gives tons better protection than anything on the market.
