This is a topic that has intrigued me for a few years. MB has had DI engines now since 2013 in series production in use in the US/Canada.
We all know that DI engines suffer from excessive carbon buildup on the intake valves. We know that DI engines generally shred engine oil viscosity due to fuel dilution due to our [censored] gasoline.
Here's the thing though.
MB and its owners on various forums have indicated that MB doesn't have the issue. However, I've never seen a photo of any intake valve in a MB engine in recent years that either confirm or deny the statement from MB that they don't have this problem.
Can anyone point me in the right direction when it comes to photos or any info indicating that MB has or has not fixed this issue?
I'd also love to see a UOA or two of MB engines in recent years that are direct injected. Thanks gurus from BITOG!
