My 2013 owners manual says nothing about semi or full synthetic oil. It does state to use 15w40 CJ-4.
Your manual says to use 15w-40 zero and above which is dino oil. It also says to use 5w-40 below zero which is a synthetic oil
Yes it does. My comment was in reference to semi or full synthetic. Interesting that it also says to go by the % on oil life or 1 year on changes. Does not have a mileage reference on changing. Got a call from the dealer yesterday wanting to change my oil because it should be changed every 3 month but no longer than 6. Truck is 6 month old and they were insistent that I not go beyond 6 months regardless of mileage. It has already had it's first oil change because I was going on a trip. I am surprised that my fuel filter shows 83% left after 6800 miles. I did every other oil change on the previous truck with about 7,000 miles between oil changes and fuel filter usually showed 25-30% remaining life.
