today I fished an empty can of Havoline out of the garbage can outside my local discount auto parts store. It is Havoline 10w40 rated SJ. I think it must be old stock as it says distributed by Equilon Enterprises LLC, not Chevron. I looked on the website at the tech data sheets and all Havoline grades should be SL. Guess you have to watch what you buy at discount stores. But maybe this old stock SJ oil is better with more of the ZDDP than the newer SL?
