Really ? Wow. Long live the 15-20 coyotes.The 5.0 in the 2021 F150 has it as well as the variable cylinder crap.
I would doubt that. On a cold start (assuming low ambient temperatures) there's no difference between 5W20 and 5W30 as both are rated at 5 weight viscosity at 0 degs. F. At operating temperatures, the 5W20 is like a 20W and the 5W30 is like a 30W.Hmmm I wonder if this is the reason my cold starts sound so horrible for the first few seconds.
IIRC they switced to 5w20 in the ZX2 because after putting some mileage on the engine the 5w30 would not actuate the vct properlyThe change was in 2001 i believe. My 2000 ZX2 called for 5w30 but my 2001 was w20. There were 0 engine changes.
Come on, guys... Does anyone really believe that Ford spent tens (or maybe hundreds) of millions of dollars to develop two updated coyote motors for the aging S550 platform (presumably one or two years before the platform is retired for an complete redesign), namely the engines for the 2021 GT and Mach1? And, coincidentally, these two updated coyote engines have exactly the same power/torque/fuel economy numbers as the engines for the 2020 GT and Bullitt mustangs? (Both the 2021 GT and Mach1 engines are specified for 5W-30 oil.)The 5.0 in the 2021 F150 has it as well as the variable cylinder crap.
My '18 GT Gen 3 (Aus) had a cap that said 5W20, but the manual stated 5W-30.As EFI asked, "What does your oil cap say?".
They would blame it for that but it was more that if you didn't change your oil on time, or ran cheap brands, it would clog it with build-up. If it was really an issue they should have changed it earlier then their universal change as all the Contour people running it since like '95 or '96 would have been crying about it too.IIRC they switced to 5w20 in the ZX2 because after putting some mileage on the engine the 5w30 would not actuate the vct properly
Well I mean, they did chance from a viscous harmonic balancer to a solid type for some unknown reason. Little changes happen all the time. I know they wont bring cylinder deactivation to the Mustang since they have been trying for years not to, but other than that any other change is fair game, especially if it solves a design issue or reduces fixed costs.Come on, guys...

The fact that Ford updated the coyote for the 2021 F150 (the year of a total redesign, and an engine which makes 400HP and 410 lb/ft of torque, I believe) does not mean that Ford redesigned every coyote enginethat it makes.
Seems that some people really want to believe that Ford changed the engines in the 2021 models (I guess, to explain the change in oil specifications).
5w20 & 5w50 have the exact same cold temp range.recommend 5W-30 engine oil for the not so cold Australian conditions
I doubt it's rated for sustained high RPM, so hopefully nobody lolSo...who is going to be the first to do an F150 oil pump swap into a Mustang 5.0?
