I am fairly certain I will drive this more than the old truck so I thinking 5000 mile oil changes.
Funny the M1 5W-30 is Dexos, but the 10W-30 is not. They have almost identical specs.
I am not worried but wanted your thoughts on the 10W-30.
For a warmer environment and in harsher conditions the recommended grade and specification lube is used.
