If that were the case Ford wouldn't recommend 5W50 for track usage.Or maybe it is so the oil will drain back from the heads fast enough to keep some in the pan at 7000 rpm.

Nope, with 10 quart capacity and deep sump, not an issue.Or maybe it is so the oil will drain back from the heads fast enough to keep some in the pan at 7000 rpm.
Ford recommends 5W-30 for track use.If that were the case Ford wouldn't recommend 5W50 for track usage.
It's not. This has been discussed to absolute death over and bobistheoilguy.com. Don't drink the coolaid. It's definitely about CAFE. There's not a big enough viscosity difference between 5w20 and 5w30 to make any meaningful difference in such a scenario.Or maybe it is so the oil will drain back from the heads fast enough to keep some in the pan at 7000 rpm.
Ford actually did change the recommended viscosity, for track use, to 5w30 for the 2018 and 2019 MY. 2020 is probably the same but I never bothered to look it up first hand. It might be because the car goes into limp mode well before temps will reach a point where 5w50 is actually necessary.Ford Racing/Ford Performance recommends 5W-50 for all Coyote engine variants for the track/HPDE. Can't hurt to give them a call if you want to hear it directly from them.
Oil consumption, 2K rattle, BBQ tick, fuel dilution, has gas guzzler tax anyway so Ford went for better engine protection. Could be any or none.My speculation and opinion: Ford switched from 5W-20 to 5W-30 due to oil consumption.
100% agree.Oil consumption, 2K rattle, BBQ tick, fuel dilution, has gas guzzler tax anyway so Ford went for better engine protection. Could be any or none.
When operated at high temperatures above intended use, yes. A 5w20 oil at 260* (130*C) is no longer the same viscosity as at 212* (100*C) where it was intended to be operated at. Thus the need for a thicker oil to begin with so that as it gets heated up and thins out it maintains the minimum viscosity needed.But do we actually know that higher viscosity equals better engine protection?
There's always going to be cons with anything you do. If you track your car, one negative is accelerated engine wear either due to the load put on it or the "out of spec" oil you put in it. There's just no real way to have your cake and eat it too. Racers have to understand this.is almost always going to operate out of spec then.
