Just this past weekend I bought my first truck, I decided to go with a diesel and it had to be a Ford. My question is simple...what all should I look into when it comes to replacing or servicing...initial maintenance? What should I include in my initial "tune up"? Its got 170,XXX miles, she runs, looks, and operates like a charm. I already requested an OASIS report, hopefully it comes soon. Please help a novice like me get my head in this diesel world, need some pointers. Thanks in advance.
