yeah, thanks John, I did a bunch of Amsoil research last month and saw this and another study where RP was a poor performer in the shear test too...so I'm in the process of switching over to Amsoil. Turns out you can get this for a little less than RP, so it's a no-brainer for me

I been using Mobil 1, but thinking of the new Castrol Edge. Guess it out performs Mobil and have always been a fan of Castrol. Have a very funny and true story to tell about Castrol oil but to long for here. Remind me next time we meet
