going in tomorrow for my second oil change. I made a pretty big production on my first oil change. I placarded the vehicle in multiple places "dexos 2 only". This time when I called to schedule my visit the dealer called and told me they have dexos 2 in stock. I will still insist on being provided with an empty bottle of oil as proof. Wrong oil will prematurely clog up your DPF.

I think we are both right. Soot is bad for the engine. Ash is bad for the DPF. Dexos to is good for both issues. DPF, SCR, EGR, DEF,ETC. I wish we could get rid of all these acronyms. Ash Accumulation in Diesel Particulate Filters

My oil change went smooth last Monday. Dealer put an empty bottle in the trunk to give me some assurance that they used the right oil. They seemed happy to do it. They topped up the DEF fluid for free without question also. I grumble and look at the time while I am waiting but when I see the bill and realize I saved 100 bucks I feel better. It all depends on dealer confidence weather its worth 100 bucks or not. Risk vs. reward.
