Here's my questions. Bought this new, have 6000 miles on it had the dealer do the semi synthetic oil change. I have 3 move free oil changes with the Ford semi synthetic oil. I would prefer Mobil 1 extended in it. Over the long haul, do you think the semi over the full synthetic will make any difference? I drive it easy , no towing, and don't beat on it. Appreciate your thoughts.

Get your money's worth out of the free oil changes then do whatever rustles your jimmies after that.

+1; let them do the free changes, make sure it's 5w30 (on F150 forums a lot of time the dealer puts in 5w20 instead in the EB) then go with what you want.

Or, if you don't mind paying for the extra changes yourself, just put your oil in next time the OLM goes off.

Likely no different in wear over 20k miles.

Motorcraft is good oil. Get the free oil changes and then do whatever you want.

Don't be afraid to get into the engine occasionally. These turbo-DI engines are not good "city driving" engines. So put it into sport mode and have some fun to warm them up. They like to be driven.

Fuel dilution can also be a problem, so I recommend a UOA to see what's happening inside the block.

Forget free oil changes. How much you will save? Engines are expensive, oil is cheap.
That engine has fuel dilution issue. Personally, I would use M1 0W40 FS or Castrol 0W40.

Do the free changes. The oil is decent, and your not doing anything tough to it.

I agree with Edyvw on this for the most part. Get either Castrol 0w40 or Mobil 1 0w40 and run either one of them. I would add Castrol Magnatec 5w30 to the list because on here it has held up it's viscosity very well in these ecoboost motors.

I recognize you have an EB, but is all of this true for the completely new EB with dual injection? The new motor shares the same displacement. That's it.

This engine has been out since December. Did I miss UOA's that show this engine has fuel dilution issues?

I tell them to keep the free oil changes. Too much hassle for me to go back to the dealer for an oil change. Then there's the risk of one of the many horror stories we often read here about an oil change gone bad at the dealer. To me it isn't worth it. Mobi1 1 5W30 EP is a good choice.

Use the free oil changes, and make sure they put in 5W-30, after that i would use Castrol Magnatec 5W-30.

I would also use the free dealer oil changes. Syn blend will not hurt your engine at all. Plus, the dealer will have record of this maintenance.

What makes you thing the Mobil will do a better job other than in sub freezing temps? The oils mostly fuel dilute over the oil change interval.The posted uoas are a valuable tool use them
