Man, you used to be all about Ford and Mobil 1. Now you're a Dodge and Castrol guy. What happened?
I still love my Ford's, but having access to dealer software for the Dodge products gives them a certain edge
Also, while I still have a fondness for M1, Castrol 0w-40 is recommended by Castrol for SRT applications, whilst M1 0w-40 is not recommended by Mobil for the same applications, making the Castrol product the safer choice.
