Thanks. Makes sense then why tech filled with 5w-30 on the 2020 then.For the 21 model years ford switched back to 5w30 for the 5.0 liter due to the oil consumption issue these engines have had. I was a technician at ford.
I'd bet they are putting 5W-30 in all the Coyotes that they service.Thanks. Makes sense then why tech filled with 5w-30 on the 2020 then.
They also added cylinder de-activation in 2021, so it might also have to do with that. My 2019 5.0 used oil, but I don't think it was because of the 5W20. It was leaking into the cylinders through the head, so that points to something faulty in the heads.For the 21 model years ford switched back to 5w30 for the 5.0 liter due to the oil consumption issue these engines have had.

It was several things. We used to replace dipstick as a TSB. Stick had a longer range. As technicians we were told by the engineers it was mainly for the oil consumption issue. GM has the displacement of demand and active fuel management using 0w20 so it has nothing to do with that. I personally wouldn’t run 0w or 5w20 in anything that recommends it. Look at all the timing chain issues in the old 5.4 liter too!They also added cylinder de-activation in 2021, so it might also have to do with that.
