It does not have the numbers you listed on the back of the box. It's API SN Plus and ILSAC GF-5.
It's not Dexos 1. Hopefully this oil will be OK. It seems to feel real good in there.

says it is Ford WSS-M2C945-A (SAE 5W-20) which matches the Owner's Manual.
In the future, you may see WSS-M2C945-whatever and those would be fine too.
It is strange the Havoline jugs and bottles do not have it printed on the back. It stinks because people in the stores can't tell.
Thats not even a tough spec to meet anyway.
In reality, the dexos1 5w20 spec is a better oil, and VW 508 & Mercedes 229.71 0w-20 oils are still better, for more coin. Ford may not want cars still under warranty to deviate from WSS-M2C945-whatever.
My choice in your car would be Castrol Extended Performance 0w-20 at walmart which meets Mercedes 229.71, although it doesn't say it on the jugs or bottles either. Mercedes says it is though.
That same oil in 5w-20 should perform about the same as the 0w-20, but its not strictly 229.71 proven.
There's your answer your oil meets the spec and will be just fine
