Based on Castrol's specs the 5W-40 used at the dealership appears to be as good as the 0W-40: Castrol
Are you saying the dealership is using a substandard blend of Castrol? Are there any specs available for this blend?
Castrol 5W40 does NOT meet MB 229.51. BIG difference from 0W40 that meets MB 229.51.
Castrol 5W40 is HC oil, probably really cheap base stock. 0W40 as far as I know is PAO.
The backside label for Castrol 0W-40 that is available on Amazon (Castrol 0W-40) does not list MB 229.51, just MB 229.5. Are you referring to a particular blend that is not available in the US?
