5w20 Factory Fill

[m6pwr]

Does anyone know with any certainty whether the factory fill on the Mustang GT and Ecoboost is the Motorcraft syn blend, or is it the full syn version? And if it's the syn blend will the olm sound of at 5k mi or take it all the way to 10k?

I don't know what the oil is from the factory, but I do know the oil life monitor is based on how the car is driven. If all stop and go city miles, then you can expect to see it around closer to 5k miles. If all highway, it may go past 10k miles.
