Where's the fuel dilution? The report is "TR" for trace that is too low to report a percentage value.
This my fourth gas turbo engined vehicle since 2000. I used HTHS 3.5 premium quality euro oils in the previous 3 vehicles and NONE of them had a UOA report as good as this one - although they were very good.
From this UOA the Motorcraft Blend oil appears to be excellent in this application. I'll keep using it until an UOA indicates otherwise.
Besides I've got 3 free oil changes with the Ford dealer to take advantage of.
Why are you so concerned with the engine oil samples (having UOA's done), being you get rid of vehicles every 4-5 years - that in all likelihood, have under 100K on the odometer, when shopping for the next new one?
Because being a technically oriented person I prefer to have actual data on how well the oil and engine are doing.
I do keep cars a long time however. Three previous vehicles from new put 210k, 325k, and 230k miles on them before moving on. Just in the last few years have I changed cars in a short period in that my needs changed. I no longer needed the Duramax or the 01 Audi S4. The dmax 2500hd was just too uncomfortable on long trips and the S4 was getting expensive to maintain for a daily driver.
Now with the Audi A6 and F150 they will be kept for a long time.
