This is why I was very happy to hear that the updated Pentastar in my new Jeep JL Wrangler does not have direct injection.
On the other hand, I didn't know anything about issues with DI when I purchased my Ford Transit Ecoboost. However, when they tore my engine down after a quick oil change place ruined it by improperly installing the oil filter, the Ford dealer told me the valves actually looked pretty good. It had about 85,000 miles on it. I ran Mobil 1 EP 5w30 exclusively from the first oil change onward. A couple of OCI's went out as far as 10,000 miles, so I feel pretty good about that plan. My understanding is that Mobil 1 AP was developed moreso with turbo DI engines in mind, so I may switch to that on my new (factory rebuild) Ecoboost, and continue with 10k OCI's.
I wonder if the NOACK changes on the oil as it gets miles on it?
