Dexos Oil

5W20 syn-blend, is the Ford industry standard. Why are you searching for 5w30? Dexos is also syn blend, made/approved to to GM spec. Don't mess around with a new engine. Your Oil life monitor, is just a guide. Dealers hate giving the "free" oil changes. They want you to come back when other things are needed, like inspections or tire rotation. I encountered the same thing at the Lincoln dealer. I was at 6 months, with break in oil and it still wasn't ready. They actually argued with me about it. I insisted and they pulled it the back. I walked around to see into shop. I never saw them changing the oil. They told me they don't give receipts, with the free oil changes, that is was "in the computer". I think they scammed me and did nothing. I then went out and bought the oil and filter and did myself. My father had the same issue with his oil change on his Toyota. They told him, it wasn't needed. That made me wonder if special "break in" oil is used. I have been using full synthetic and change mine once a year. I own 3 vehicles and none get driven more than 4,000mi.

You don't have to use Motorcraft oil. Any 5w-30 will work. Ive used Castrol and Mobil 1 in my 17 EL

I do think the oil life monitor is somewhat intelligent. An example being just this past weekend. We went camping and brought our toy hauler loaded to the max which was probably in the 8500-9000lb range. It was 300 miles round trip. When we left the oil life was at 33% and when we returned and I got home it was at 24%. No way just normal driving for 300 miles would the monitor have dropped 9%. It knew I was pulling a load and was taxing the motor there for it adjusted. IMO that's somewhat intelligent. By the way at 33% I only had 4400 miles since my last oil change and I use full synthetic. I don't think the monitors are designed to allow you to go 7000-10000 miles before a change. I think with full synthetic 5000 is a good number to change oil at

And chances are if you let the dealer change it they will put in 5-20 like they did to me twice.

Why? because that is the recommended oil to use. It clearly states for my 17 to use 5w-30. The alternate oil that is recommended is FULL SYNTHETIC 5w-30. Not 5w-20. I am somewhat baffled as to why some folks are questioning my seeking 5w-30. It is the oil STATED to use.
