I am running Amsoil but a lot of guys think it is a high dollar oil but so is my motor so that being said i would go with Rotella T6 5w40 and the 04 has a external trans filter up front next to the raditator on the right side.

Use a full synthetic 5w40. I would suggest you get the Racor filters as they manufacture them for Ford and are much cheaper.

dieselfiltersonline.com is a great source for all your filter needs.

Almost any guy you talk to will tell you to use a different oil, choose one that is easy for you to get your hands on that is reputible, and get a quality filter. Change it when you are supposed to and it will be fine. I personally run amzoil and there are some definate advantages to synthetics the main reasons i run it is the extended drain intervals and the cold weather starts. if neither one of those are an issue for you, quality conventional oil like rotella, delvac, or valvoline blue will be fine.

Not the best advice I have seen on this board. Quality conventional oil leads to injector stiction. And just about everybody knows you can't run extended oil change intervals with a 6.0. The high pressure oil system that fires the injectors shears the oil like crazy and it is just worn out in about 6k miles. And yes I'm talking about Amsoil. We had a couple Amsoil vendors that are sponsors here that kept talking about Amsoil being shear stable and I called them out on it every time I saw it. When I proved it wouldn't do extended drain intervals with a Used Oil Analysis Report they got on the line with Amsoil's R&D guy. They asked what was up and showed him the UOA report and the answer was "yeah, we know. We're working on it." I haven't seen a post from either one of them since.

5K-6k is the change interval with a synthetic. Conventional oils break down much faster.

Solid advice there! I am running the oil I posted the link above and it works great. I still will not run it past 5K. It's just not worth it.

i wasnt saying you can do extended drains on a 6.0 i have a 7.3 and i do and thats one of the reasons i run it, but i would say if it meets the specs in the owners manual for most people it would be fine, as long as you change it like you should. isnt that what the specs are for? although i must admit im not an expert and i dont know a lot about the 6.0's so you should probly listen to someone with 1st hand experience! i am not aware of the oil analysis reports, should i be worried in my 7.3?

Your 7.3 also runs a HEUI injection system and suffers from the same shearing as the 6.0. If you are running your oil past 6k miles without having an analysis done on it you are heading for trouble. You can get free oil analysis test kits from Blackstone Labs to send your oil sample in and it costs about $35 for analysis. By doing periodic oil analysis you can do a base line and trend analysis to see if everything is healthy. It will pick up accelerated bearing wear, fuel dilution either by fuel or antifreeze etc., and give you the current status of the oil such as viscosity and usable additive left in the oil.

Bottom line is you can not run the 7.3 or the 6.0 on extended oil change intervals in spite of what you read in ads.

interesting, now i guess i have something else to research i may be in trouble already though because the guy i bought the truck from as already been using amzoil for the last 50,000 miles i always thought it would actually be better for the high pressure oil system
