So what does it mean when one runs a "frankenbrew" of multiple grades (I had a blend of 5w-20, 5w-30, 10w-30, 15w-40 and SAE 40), oil types (conventional, syn-blend and synthetic) all from different brands?
My engines rarely see the same brand oil more than one oil change, but I usually stay the same weight.
