I'm sure I am overthinking this, but I noticed that the Mobil 1 PDS wording is different across the grades they offer. Their data shees are always updated and very clean. XOM clearly puts time into making sure they are up to date. I did notice though that "cleaning" is used in only the regular M1 grade and M1 0w40. Could this be due to the concentration of AN's and POE in the 0w40?
