To be fair, the manual doesn't state the reasoning behind the viscosity change which is what the OP is asking for. But I do agree that there's whole other thread on this with more info that the OP should go read.
Isn't the general consensus it was basically to shut people up about The Tick?

My guess is no, simply because we have not seen a direct correlation between thicker oil and tick being gone. I myself have been using 5w30 for 5 years and it still ticks away.

Swapping the oil this weekend, for no reason. Other than I was never sold on the 5w-20, in the first place. The 5w-30 was on the radar.

Glad Ford is now formally pushing the next grade, makes total sense.

I think it's simpler than that, the Mach E is offsetting enough CAFE points that they don't have to nickel and dime the rest of their fleet anymore, and the 5W30 may lead to fewer warranty claims.

Our Aussie S550 GT mustangs since 2015 have always used 5w30 oil and it says it in the owners manual 5w30 . Yes our oil cap did say 5w20 a s still does .

I won't even look, 5w30. I have a v6 and the manual calls for 5w20. After 4years of driving it with 5w20, I decided to give 5w30 a try. The major reason that I'll stick with 5w30 is that the engine sounds smoother with exact brand and line up of the oil compared to 5w20(Pennzoil ultra platinum). With 5w20 the engine runs so clunky. I'd never go back to 5w20 and I'd never go higher than 5w30. Just enough viscosity to keep things running smoothly.
