I am picking up a brand new 2022 Mustang GT with the 5.0L V8. Currently 2021-2022 models calls for 5W30. The 2018-2020 were calling for 5W20, all mustang V8s in these model years are identical Gen 3 in terms of internals. The 2015-17 Gen 2 Coyote called for 5W20, and so did the Gen 1 from 2011-2014. However; performance pack models at that time called for 5W50 to be used, even though the guts are the same. So I have a large hunch that Ford designed this engine to wear best with a thicker oil and tried to get away with as thin as they could recommend to meet CAFE/EPA/ fuel economy benefits.
Roush and Whipple who make superchargers also recommend 5W50 for the boosted Coyotes.
My car will be staying stock minus some basic bolt on mods, but it will get driven hard occasionally.
I’m from the Nissan VQ35 world (hence my username) where 0W40 is praised over the factory 5W30 since VQs have a tendency to shear and burn oil.
Once I get some positive results from Blackstone after a few oil change analysis, should I move up to a 0W40 to provide equal cold start protection but have a bit thicker viscosity at full temp for when the car is driven hard?
In the mean time, I plan to run 5W30 Pennzoil Ultra Platinum for a few cycles after I drain the factory fill at 1K miles.
