I’ve been running Schaeffers 9000 5w40 in my 6.0 powerstroke and lml duramax for years now. I was wanting to run it in my new 2019 6.7 when the oil monitor tells me to change it. I looked on a list of approved oils for the 6.7, and their 10w-30 and 15w40 is on their, but the 5w40 isn’t. Has anybody used it in their new 6.7s? I was hoping to use the same oil in all 3 of my trucks, but I might have to swap to 15w40 to do so. I’d hate to run anything other than the 5w40 in the 6.0, and Schaeffers is all that I will run. Any help would be appreciated.
