    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    No ford recommends CK-4 for severe duty service. And from what I read that includes pretty much anything.. extended idling, stop and go traffic, extreme temperatures, towing, biofuel use, etc. That to me is ford giving the wink that this is probably the best oil to use, where FA-4 helps them...

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    That chevron 0W30 is a weird one, 3.1 HTHS which is in the range of an FA-4 oil and not a CK-4. but it also doesn't have the WSS-M2C171-F1 ford stamp of approval, so probably not a good one to use while in warranty. The only 0W30 meeting that spec that I could find was the Klondike one that I...

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    It is a really low HTHS oil, and in the manual says it's not recommended for severe duty service. According to ford, this can be extreme temperatures, idling, towing, stop and go traffic, mountainous terrain... basically everything one would use a truck for. So to me that oil would only be the...

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    The Mobil-1 Delvac ESP 0W40 might be a solid bet too year round I'm thinking. It carries the WSS-M2C171-F1, for some reason it's the only delvac grade to do so, which I believe means it has to have a phosphorous rating of 1000 ppm. Oddly it still carries the SN rating as well which I didn't...

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    True. It's by far the easiest to come by. I should probably just switch to this and be done with it.

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    The 0W30 says in the PDS that it "meets the requirements of" the WSS-M2C171-F1 specification, but I don't believe that it has a full certification. The specification listed in the manual only applies to the FA-4 oil, they don't list a ford specific one for the CK-4 oils in there, however say you...

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    Yeah I agree. If they say CK-4 can be used, it's probably the better choice for wear over the FA-4 I would think.. although all the PR materials say it's "equivalent" protection.

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    Yeah lots of guys on the forum seem to run this without issue, especially for towing. I just know that the bearing spaces where increased to accommodate for the FA-4 oil which I assume needs higher flow, so i'm wondering if the 40wt would be too thick for everyday normal use.

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    I have the 0W30 in there now, according to their oil reference sheet posted above this is fine. I will probably get an oil analysis done however at around 7000 km to make sure all wear metals are looking good.

    Ford 3.0 Diesel - to FA-4 or CK-4, that is my question.

    Hi All, I'm looking for your expert opinions on the best oil choice for the Ford 3.0 Diesel, as there are a lot of conflicting views out there on which oil will offer the best protection, even from ford themselves. The 'Preferred' Oil in the manual is their FA-4 spec 5W30 diesel oil, however it...
