I'm glad I can put 15/40 Rotella in the crank case and after 10K change it. My Duramax always starts up and runs clean and never misses in cold weather or hot weather or any weather.
I guess I'm lucky because I don't need additives.
Duramax diesels have issues as well. Not to start a flame war but I won't have one because it's in a Government Motors vehicle. Besides, when I purchased my '97 in '97, the Duramax wasn't around.
My turbo seems happier too... She's whistling constantly now...
