Mobil claims that the "loss" of CF is because its an obsolete standard and that the 15w50 still meets the CF standard even though its not on the bottle. I put it in my 240D a few thousand miles ago and it hasn't blown up yet ;)
M1 5w40 ALWAYS had CI-4 on the bottle and met with approval on the list. I have yet to see anybody give convincing proof (like analysis) that it doesn't have zinc levels that are adequate. Basically my contention is I understand where you're coming from but you haven't offered ANY proof. I haven't either but I'm not contending that things have changed. -Curt Date: Mon, 15 Aug 2011 18:47:27 -0500 From: Dieselhead <126die...@gmail.com> To: Mercedes Discussion List <mercedes@okiebenz.com> Subject: Re: [MBZ] lubromoly oil Message-ID: <a06240891ca6f5e3f3ebe@[10.10.100.225]> Content-Type: text/plain; charset="us-ascii" ; format="flowed" I just checked my stock of M1 and it is SL/CF. I know most of the new M1 stuff carries no Cx designation, because it is not suited for Diesels of any sort. Therefore the M1 "Diesel Truck" was brought out that is formulated for 2007 up Deetriot pickup Diesels. I think it was the time before last that the M1 thread ran that the lack of Zinc and phosphorous was discussed in depth. In the years since 2007, we have seen CG-4, CH-4, CI-4 and now CJ-4 designations. That should be some clue that the 2007 engines have caused a huge disruption in the motor oil business. At the same time, the ULSD has lost the lubricity required for older Diesel engines. A B5 blend for Diesel fuel provides the lost lubricity, and at least 5% of it is made in the USA. To your many miles and many moons of HAPPY Dieseling!
