So what oil do you think would work good? Ford calls for 5w30.
Thanks
Since this is a pretty new fuel delivery system, and it should improve the fuel dilution situation, if it were me, this is what is what I would do. Get a Ford Fastlane oil change/tire rotate at 2,000 miles. They are cheap. It will get the assembly/wear-in crud out. Run that change until 5,000 or so miles, and do a used oil analysis. If no fuel dilution/shear, just start running the OLM.
