After researching different brands to use, came across AMSOil and saw they had a local distribution center near me. Ordered and picked up the same day. Great pricing through the membership, so changing all of my fluids over to AMSOil when needed.
Test after test after test confirms that Amsoil Signature Series is best oil to be putting in your vehicle, and it's the only oil I purchase for my Honda CR-V.
Bottom Line
Yes, I would recommend this to a friend.

I run my TT 22' Mach 1 HP hard, and this oil protects my engine better than any other oil I have used.
Still slick & semi-clean when draining it at <10k miles.
Bottom Line
Yes, I would recommend this to a friend.

In all my vehicles

The results of oil testing show me less wear than subaru oil, or name-brand 5w-20 suggested in my mechanic circles for modified/performance engines that run 0w-20 in a warm climate. My oil tests show significant wear and oxidation protection package and significantly less wear than "stock" oil or aftermarket "performance" oils I have used.
