Re: What fluids to use for 6.0L
Pretty new to this myself, but I've been told to run only motorcraft/racor filters (oil, fuel, air). Racor makes the filters and Ford puts Motorcraft on the box. As far as motor oil, most people say run a 5W40 synthetic but I'm sure there's a million different opinions on that subject. I'm not sure about trans. fluid, you'd have to ask someone or do a search on this site. There are some really helpful people on here and a ton of helpful threads. Also, the 6.0 are very sensitive to lack of maintenance so make sure you are changing fluids religiously. Good luck.
