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 does state that for 'severe duty' service to use a 5W40 API CK-4 oil, or 0W40. It gives the ford spec WSS-M2C214-B1 for the FA-4, however does not list a spec for the CK-4. On the ford quick reference oil chart located here (oilchartUS.pdf (fcsdchemicalsandlubricants.com)), it does state in a foot note that the WSS-M2C171-F1should be used, and that 0W30 is ok as well. It does not say explicitly that a 5W30 CK-4 is ok, however I assume that this would be fine given this is the preferred FA-4 viscosity.
It is of my opinion that the FA-4 oil (low HTHS viscosity) is being pushed mainly for fuel economy, however if ford states to use a CK-4 for 'severe duty' service, then that is ford giving a wink to me that this would be the best choice of oil to use for long term protection. Since there is no description on severe duty service provided, I'm thinking that since I live in canada, in a city, that pretty much qualifies me as such. I tow a tent trailer in the summer (3500-4000 lbs), but that's about it.
I'm torn as since the FA-4 is preferred, that would mean that the engine is designed for this lower HTHS viscosity, and thus would using a CK-4 be too thick? It also looks like this engine has been using a 5W30 since inception going back to 2007 ish in the JLR applications, so would using a 40wt oil lead to lower oil circulation during normal operation over a 30 wt? Right now I'm leaning towards two oil options. The petro-canada 5W30 CK-4 oil, or the Klondike Lubricants 0W30 CK-4 oils, with a middle ground HTHS of 3.5. Both of of these "meet" the WSS-M2C171-F1 spec. Since the manual doesn't explicitly state the CK-4 spec, is any CK-4 then good to use, like say the chevron 5W30 CK-4 that doesn't have the ford stamp of approval?
In closing, if this was your truck, and you want to keep it for 10+ years, which lube sauce would you put in it to help it last. Thanks!
