Well I bought a 2008 F-250. Now I have a truck with 417,000 miles. I replaced all 8 spark plugs at 365,000 miles. I have 7 of 8 orignal coil packs/brake shoes/drive train and rear end. I still get 16 miles to the gallion. I change th oil and filter every 7000 miles . I pack the wheel barings @ 80 to 100 thousand miles. Iam very pleased with this truck. Thank you. Waiting to here from you.
