Chris, Consumer Reports has many articles on mineral oil vs synthetic oil and I agree with most of their comparisons. Synthetic is costly but is good if you make a lot of short trips,live in a cold winter climate, do a lot of hauling like trailers etc or if your engine runs hot under towing and hauling then the synthetic resists breakdown from heat. Another factor if GM recommends the synthetic for Corvettes then it is probably better for a truck also. Anyway it is a personal decision based on many factors. Good luck.
