2017 Base model GT with the MT-82, and bought it used with 21,000 miles. I daily drive it about 325 miles a week. Now, it is sitting just at around 32,000 miles. I have not kept it stock, it has full bolt ons and e85 minus cams if you want to count those. I do at least a few WOT pulls every day...
Your owners manual in your car will have a list of all recommended services and at what mileage. Never go by what Ford says at the dealership for recommended services.
