Someone posted on SVT that Ford has replaced Motorcraft 5w-50 with Mobil 1 5w-50 in the Boss both right from the factory and as the dealer replacement.
Is this true?

Only Motorcraft 5w50 and Redline 5w50 adhere to this spec.
Not that that actually means anything in the real world, I'm sure Mobil 1 5w50 is on par or superior to Motorcraft 5w50.
I did my first oil change with Motorcraft and will be using Redline from here on out.

It does not state that it meets the spec.zzyzx said:Dean#4AI said:Hmmm, are you sure about the Redline having that spec?

"Popular for 5.4L Supercharged Ford applications like Shelby GT 500 and Ford GT (WSS-M2C931-B)"
That's my understanding. I wouldn't hesitate to use a non spec high quality motor oil like Redline or M1. I was just pointing out that Redline doesn't meet the spec. I get my oil changed at my dealer for less than it would cost me to do it so that's why I use the Motorcraft. A local shop to me stocks the M1 in 5w50 and that's what I'd use if I was changing it myself.gremlinsteve said:Doesnt this ford spec oil just mean its a low
