Mixing oil weights
My 6.4 always ticks when it starts. The MDS and and VCT are requiring lighter oils. I run Mobil-1 at the recommended weight. The fuel injectors also make noise. This is my first Gen-III, so things are not the same as my Gen-II dump-truck hemi engines. They don't need gear lube weight oils.
