First post and UOA.
We all know the 3.5 Ecoboost destroys oils. I change at 4,000 miles and have since the truck was new. I have a handful of reasons why: It's easy. Oil is cheap, engines, timing chains, phasers and turbos are not. I want to keep it in a 30 weight or above spec, and it's a satisfying feeling when I'm done. Overkill? Maybe.
I have only used Castrol Edge 5W30 U.S. When I got the truck, API SP oils that mentioned meeting Ford's new WSS-M2C961-A1 were limited, and I read good things about Castrol handling shear, mostly from the Magnatec crowd. I'm aware there's a lot more oils now and I am open to suggestions.
Here is my report:
Overall I am pretty happy with the results. Glad to see it's 100C Viscosity is 9.61, only dropping slightly from Castrol's advertised 10.0 starting point. Of course these results are based on my driving style and fuel usage. 91 E10 only, about a 30 mile commute, half of which is freeway so I am pretty much always hitting operating temp. I also deactivate auto start stop every time I start the truck for what that's worth and tow a 5000 lb trailer every once in awhile.
Let me know what you think!
