Hello Bob and others,
I came across your forum and wanted to get your advice. I have a 2014 Mercedes 250 Bluetec diesel. This is the 2.1 liter four cylinder with twin turbo. Because of the DPF (planning on removing it in the future) Mercedes is recommending an 229.52 oil and most are using Mobil 1 either 0-30 or 5-30. I recently read an article by a guy who maintains these engines and because of the high heat they generate he says they have a “coking” problem with the Mobil 1. He recommends Redline 15-40.
I’m over my head and everyone has an opinion. I would like to keep this vehicle for a long time and I have a shop here at my house and the experience to do my own service. I don’t mind paying extra for the best oil and frequency in oil changes but at this point I am at a loss to know the best oil to use. Any advice you could give would be greatly appreciated.
Thanks
