I'm not too sure what oil life parameters Ford uses. For our 2.3 Eco Boost it seems that you lose 1% oil life approximately every 100 miles. This happened from April through most of June, not a warm time period here in NJ, 3,200 OCI, 67% life left. Just changed it from 2 recent trips equaling 7,000 miles in 2 months, mostly high speed interstate driving in Southern heat. That OCI showed 29% oil life left, again 1%/100 miles. Yet the driving conditions were very different. This one was with Mobil 1 5W-30, I'm sending this off to Blackstone to see how the oil fared. When I changed it there was a definite fuel smell in the oil. I changed to Motorcraft 5W-30 and will run it to 5,000 miles and also do a Blackstone UOA to see how it fares. This one will be our "normal" driving conditions. I'll post all the results as I get them.

You have to keep in mind that the Ecoboost engines are different. Yes, they have DI and the turbos, but....
For instance, the 1.5 has 4.3 qts of oil, which is actually more oil capacity for displacement than the 2.7. Also, the 2.7 oil is going through two turbos, etc.
I was just looking at my daughter's 1.0 Ecoboost Focus specs(yes, they do exist in the U.S) 4.3 qts. of 5W-20. Way more oil for displacement than the 2.7.
