I have a 2014 C250. Have been following the 1 year / 10k miles between oil changes (using the MB oil).

As the engine gets older, does anyone recommend reducing the 1 year / 10k oil change interval? I know as the engine gets older, more blowby happens (thus the engine oil gets dirtier.

Thanks!

 

If your driving habits or location changes, I might consider change, however I would always refer to owners manual!
