Much sooner if you listen to my dealer. He indicated every 3,000 miles. I know the oil maintance light comes on at 3,500 miles. If I would have known this sooner along with the plug changes at 35,000 miles I would be in something else.Just got this new truck. The manual states oil changes every 8000 miles. Is it necessary to change the original oil out sonner than that?
You'd be surprised, I'm using Amsoil extended drain 0W20 and after 5,000 kms it's still golden clean. I'm impressed so far :smileup:Ya the '12s show a 8000 mile 13000km oil change schedule. I will NOT follow that. I will probably stick with the tried and true 5000km change, unless the oil still looks clean which I doubt will happen.
Same here, same oil, same mileage interval, most of the mileage being highway, with the exception of a higher-end fram oil filter.i changed out factory oil at 1000 miles and changed to penzoil ultra, 5-20, and a premium kn "white" filter" and change every 6000 miles.
