Question:
Will Mobil Oils Continue Providing SL Rated Protection
API SM appears to be a step backwards in regard to engine wear. Will Mobil oils continue with SL rated protection in its oils? Many now have SL off their bottles but show SM.
-- Ansel P. Meadors, Greenwood, SC
Answer:
Yes, all our motor oils that are providing API SM quality level are also backward qualified for earlier service categories such as API SL, SJ, etc.
