Just wondering if I would cause a warranty problem if I changed out my engine oil before the 50hr service?? I'd like to get Rotella T6 5w-40 in it before the real cold sets in. I have about 28 hrs. on it now and I'm sure there is 15w40 dino from the factory. I'd run the rotella T6 year round.:thumbsup:
