Ford has said the new ck-4 motor oils is not recommended for the older powerstrokes. do you guys have any insight on this. thank you anyone
I run Jim's 8800 in my 01 Excursion, and after I replace the injectors in my 02 350 it will be getting it also.We do have the 8700 and 8730 which are remaining CJ4. 8800, 8854, and 8130 are all now CK4, and Fords new F1 spec. So, more or less all of outlet oils are Ford compliant.

As soon as I deplete my Delo stock (1 oil change ) I'm calling Jim for some CJ 15w40. Maybe Jim could persuade LE to make some gallon jugs.

Tried and failed. Can't be perfect I guess. 2 gallon jugs is the closest I'll get.

There is Fords list of compatible oils for Fords spec....... looks like I'm good using Rotella T5.....

LE is on there. Monolec ultra engine oil in both 5/40 and 15/40. In the 15/40 its right above motorcraft...
I missed it the first time too. I will say my truck, even though its a 6.0 instead of a 7.3, runs a lot better on the LE vs the motorcraft.
Personally, I won't use Rotella in my lawnmower.
And most of your 1000+ hp marine diesels and reduction gears...... use either Rotella or Delvac....... most oil changes are done every 500 to 750 hrs on engines....... reduction gears are every 5000 hrs or 12 months...... and that's with most engines turning 1800-2200 non-stop..... avg temp is 190-210 coolant...... engine room temp is 250/300 degrees during mid day....... day what you want about Rotella, but I've seen it in action for 17 yrs on river boats
