A Lamens terms run-down on API SL certification...

Hey Guys, I'm having a hard time picking out the facts from API regarding the new SL oil standard. So, can someone fill me in on this, please? So, far this is what I know (in comparison to SJ). - 30wt. and lower oils are restricted to 10% Zinc and Phosphor content. Thanks, Oz

This here is the best article I've seen yet on describing the differences in the SL formulation: http://www.tosco.com/internet_pub/repository/lubes/44_tn3_4.pdf
