I Just bought a jug of M1-HM 5w-20 from wally mart and noticed the jug now states that it is SN rated instead of SL.
My prior SL jug purchased just last OCI states ACEA A1/B1, API SL, jug code: 11016626A
New SL jug states ACEA A1/B1, API SN/SM, jug code: 11016H24A
Neither state energy conserving or have the API starbust.
This is my first time using this oil(in the 5w-20 flavor, lots of 5w-30 use), and perhaps I just got one of the last SL rated during the change over, but I wondered what this possibly means for the additive package? The SL is doing a great job of cleaning up from what I can see through the oil cap hole.
