Switched from Mobile 1 Supercar 0W-40 and never looked back. This stuff is the best on the market. It comes out on top against all competitors in testing for a reason!
Superior protection, motor runs smoother with Amsoil. Stays cleaner than other oils used.
Bottom Line
Yes, I would recommend this to a friend.

AMSOIL Signature Oil
By

I’ve continue to use AMSOIL Signature oil in all of my vehicles! It exceeds all my expectations. What a fantastic product!
The extended drain interval makes it affordable. I would not do an extended drain interval with any other brand. Amsoil is the only lubricant my mechanic recommends because he has seen it all after 40 years of servicing everything mechanical. He is somewhat retired but still gives advice via a radio program. He warns against the inadequate lubrication car manufacturers are selling with lighter weight oil. He recommends Amsoil 0w30 to replace anything that is thinner. Works for me...
Bottom Line
Yes, I would recommend this to a friend.
