I did the math on fuel cost and after you adjust for relative cost of diesel, higher cost for oil changes (2qts more), def, and fuel filters, extra cost of diesel engine and bucket seats I don’t really want and I came out with maybe only saving 1-2k over 125k miles. Also, my trade in will need tires and brakes before too long and we really wanted a bench seat so we can get that now too.I would but the fuel economy on the 5.3L just makes no sense to me unfortunately
