How do the valvoline mst oils measure up ? I think NAPA puts them on sale occasionally
Valvoline has 2 compliant oils.
Valvoline SynPower B-Tec C3 5W-30 x The Valvoline Company, LEXINGTON, KY/USA
Valvoline SynPower MST C3 5W-30 x The Valvoline Company, LEXINGTON, KY/USA
Never once seen these on a shelf anywhere in Southern California
Mobil 1 ESP is compliant which is also hard to get
Ravenol has a formulation you can get.
The list Mercedes keeps is a joke - you'd think by looking at the list one could locate this rated oil everywhere- it is very hard to find 229.52 on a shelf where I live. https://bevo.mercedes-benz.com/bevolisten/229.52_en.html
