This How To video shows how I did a complete oil and filter change on my DT466 Engine for my 1990 International 3800 School Bus. I will post the filters that I used below, but they may not match up with what you need. Check your own old filters to see what may be required. This is my first time doing an oil change on my skoolie. Since this video was made, I've probably driven it about 1000 miles with no issues. It does seem to run cooler, in fact.

I highly recommend Blackstone Labs for oil analysis. check out blackstone-labs.com to get a free test kit.
