- 2022 Mach 1 Premium with handling pack
My 2022 Mach 1’s oil cap states 5W30.Last week, my wife took delivery of her 2021 Mustang GT Convertible (PP1, 401A, 10SP, MagneRide, Twister Orange). I had spent the better part of 2018 obsessing about Mustang GTs (before taking a break after buying a different car), so I felt pretty confident I knew everything I needed to know about this car.
So imagine my surprise when I saw that Ford now officially specs 5W-30 oil for the GT in the owners manual. To make sure I wasn't looking at the wrong information, I looked up the recommended engine oil on the Amsoil website and it indeed comes back as 5W-30. However, if I switch to a 2018 Mustang GT, the recommended oil is still 5W-20. (Of course, my assumption is that the engine itself has not changed in any meaningful way.)
I recall from a few years ago heated debates about using 5W-20 vs 5W-30. In short, one camp took the position that Ford engineers know best and why would you put your warranty coverage at risk by going with another type of oil. The other camp believed that Ford only recommended 5W-20 to meet CAFE requirements and 5W-30 will provide better protection (especially if you ever put any amount of stress on the engine).
This raises a few questions for me:
When did Ford make this change? Why doesn't Ford change the recommended engine oil for GTs from previous years (and would they seriously deny a warranty claim for using 5W-30 at this point)? Does this end the 5W-20 vs 5W-30 debate (or do we get to argue about 5W-30 vs 5W-50 now)?
