Just got the new baby- 2014 c300 w204
Need to do oil and filter change. Does it really matter about spec 229.3 vs 229.5 in synthetic oils? Was thinking of using Castrol Edge 5w40 full synthetic. It seems to meet 229.3 but perhaps not 229.5 specs. Am I splitting hairs here? Are the Mann oil filters ok to use or do I need to go with Benz dealer filter?
Want to get started on the right foot...
