New to board- What is your oil change interval?

[2000 Amber Crew Cab F-250]

Hello everyone, I have owned my 7.3 psd since new, I was wondering how often do you guys change your oil and your fuel filter?
I go around 4,000 to 5,000 on my oil and about 10,000 on my fuel filter.
This is my first ford and I have been very pleased with the PSD engine.

Welcome to the site. If you are running synthetic oil some say 10,000 miles.
If you are running dyno oil or the regular petroleum base oil then every 5,000 miles.

I change mine at 5,000 miles I have always done this since I bought my truck 5 years ago.

Welcome to the site..
The very best way to determine oil changes to to test your oil.
If you email blackstone-labs.com they will send you a kit that on your next oil change you have the tech catch some in the bottle and send it to the lab.

Not only will they tell you how much life is left in your oil or not left in it. this is called TBN. This is the measurement of how much active additive is left in the oil. The longer you use the oil the lower the TBN count.
Also,they will do a full analysis of the content.
The lab can tell from mineral content what the warning signs are of your engine. For example if there is too much magnesium in the oil it means.. blah blah.. or traces of anti freeze, then it means.. blah blah.
This lab is a early warning system. You can correct the problem before it becomes a problem basically speaking.

You can learn more at there website. They even show examples of the test report.
