I am sure this has been discussed before, but I cannot find the answer. I am considering switching my 6.0 with 100k mi over to Synthetic Oil. I just purchased the truck and spent a lot of money on new injectors and bullet proofing. I would really like to protect my investment. I have been told that this may cause oil leaks I wish I had never had such as main seals etc....Does anybody have a real answer to this?
