To do guides?

@Chrispy - you're right in that their isn't a single definitive post or forum that answers your questions.

@Dunrollin has posted a few DIY video links from FordTechMakuloco for the non-diesel related interval changes:

• Check Your Transmission Fluid Level Now - It is fairly easy to do
• DIY Transmission Service Video

and there are numerous threads on these topics w/recommendations but no DIY videos:

• Diesel oil and oil change intervals
  • Survey: First oil change mileage/% Oil Life remaining
  • Oil Change Interval
  • Oil change intervals 3.0 PS
• Diesel Fuel filters and fuel filter change intervals
  • Fuel Filter Replacement Intervals
  • 3.0 Fuel Filter Replacement
  • Poor fuel economy & rough shift = fuel filter
• Transmission fluid and change intervals
  • Transmission fluid question
  • Transmission broke

I like the idea and can work with you on sticky threads or a new sub-forum if you want to take the lead on this concept.

My first recommendation (based on @RLVoumard and @Reinharm's recent experiences) would be a DIY video on the correct oil filter change procedure (from the Ford Shop manual that @Kval posted) to combat all of the incorrect YouTube videos out there and something we can send to Ford Oil Change technicians! I'd love to see a DIY YouTube video with the following:

• Zoom of bottom of oil filter assembly showing rubber stopper and the "nub"
• Proper procedure (New filter installed on shaft/post and not clicked into the cup)
  • Show how filter will not spin after installed on shaft/post
• Explanation of what happens to the nub when you click in into the cup first
• Possible symptoms (Low Oil Pressure warnings)
• Estimated cost to repair if nub sheared off due to improper procedure

and I'll even offer to help write the script if you don't know what/how to say it.

Maybe you and @Dunrollin could collaborate on something?
