Looking at switching to Amsoil either (AME) 15w40 HDEO or (AMO) 10w40 Premium Protection in my 6.7 Cummins. I will be able to run CI-4 oil soon after a few more clean out oil changes. I was under the impression the 10W40 would be a bit better for all season (Michigan) usage and it states it's diesel approved. Plan to use Donaldson Endurance Filters ELF7349/DBL7349, looks like with this combo I can run 15,000 mile OCI provided I continue with the Blackstone UOA I send in.
Anyone using CI-4 Amsoil (AMO) in there diesel with good results?
