To keep a long story short...my new truck at work is a 2013 Ford F150 with the base V6 engine. It's the Duratec 37 Ti-VVT twin independent overhead cam engine. Ford is calling for 5W-20 as they do in most models. However the service department where I work only stocks two oils....Citgo Citgard HD 15W-40 diesel oil and Citguard 600 10W-30 HD diesel oil. They are not interested in stocking SAE 5W-20 for me specifically. Nor SAE 5W-30 for the Chevy or Dodge trucks we also have. Everything used to get 15W-40 period. But the recent addition of 13 new F350 6.7L Powerstrokes calling for CJ-4 10W-30 was enough to get them to purchase the diesel 10W-30 finally.
I'm not too comfortable using either type/grade in this newer technology Ford engine...but the service department seems to not be concerned at all. They usually aren't concerned about much at all now that I think about it. Nor do they have ANYTHING to base their decision on other than "we've always done it this way...it'll be fine".
Historically, most pickups we get go to 200K before replacement. Out of five 4.8L Chevrolet gassers...three had severe ticking (then knocking) problems at 150K. Two of those three locked up engines suddenly. They received reman engines. The third got a new oil pump that saved it (it seems). So I'm not sure if the 15W-40 played any role in that or not. I believe all 5 Chevys had to have new converters at some point.
The sole Dodge Ram 1500 4.7L V8 seems to have been the best gas truck we've had in recent times. No issues ever and still going strong at 160K. The Dodge was mine prior to this new Ford. It always ran 15W-40. (But I'd sneak my own 5W-30 in it during Jan/Feb cold snaps).
Any thoughts on running a conventional Citgard 10W-30 HD diesel engine oil (CJ-4/SM) in a new "high tech" Ford V6 Ti-VVT? I'm thinking we will get by...but without knowing what kind of long term damage we are doing, if any.
