Can I use 5w40 oil in 2022 CTD?

I've read multiple places that concur with that statement up until 2019, the latest info suggests that 19+ have 10w-30 as the factory fill.

That's backwards; it was 10W30 synth blend at launch, and later changed over to 5W40 full synthetic.

That's backwards

It can't be backwards as the 10w-30 wasn't an approved oil until 2019.

I've found that 13-18 was 5w-40 from the factory and 19+ is 10w-30. Do you have anything showing otherwise?

Scroll down to the fourth paragraph, it is a 2020 article so maybe now it is something different?

Hence the "10W30 at launch"...I meant launch of MY19. It changed over to 5W40 Valvoline Premium Blue Extreme in mid 2020. Prior to MY19, it was 5W40 synthetic for pickups and 15W40 conventional for CC.

Yes, I do have documentation, but can't/won't share it.

Thanks, makes sense.

That's not for pickups, just Midrange.
