One of these goes in my transmission pan:
2" NEODYMIUM BAR MAGNET | AllElectronics.com
Two of these go in some of my filter flanges:
0.105" X 0.2" X 0.4" NEODYMIUM MAGNET | AllElectronics.com
If you're going to use magnets to grab ferrous materials in your oil, neodymium is the way to go!.
I'm currently dumping my dino Delo at about 15,000, and could probably stretch it another couple of thou, but choose not to. As Alex related above, you don't go that long without the spending the money with the guys in Ft. Wayne (or their competitors).
To get an idea of how my engine is doing with this change interval, see my Blackstones at the bottom of this page:

It's not for everyone, but it works well for me.

I was running the lucas oil stabilizer but began having a problem with oil foaming. No more lucas for me! With the synthetic, depending on how you are using the truck and how much idle time, you should be ok for at least 8,000 miles. I would grab a sample at that point and get an analysis run and let that tell you how much longer before your change it out.

What about Additives?

Virtually nothing, except for the transmission filter, which is absolutely minimal. I would hope that's because there is very little to catch. When I first started using them there used to be a little more.
I'll have to grab a picture next time I change a filter to show you.
The small magnets are in my hydraulic filter system, the transmission fluid system, and the lube oil bypass system. There are none in the flange of the primary, full-flow lube oil filter.

I was at the shop yesterday after my run and was told something interesting...The new Detroit DD-13 through DD-16 engines have been certified to a 50,000 mile OCI 
! I did some research at home and sure enough, 50K with analysis and the oil does NOT have to be synthetic. Let that rattle around in your brain...Granted on a longhaul truck that is anywhere from three to six months, but it still is 50K! Oh and no need for intermediate filter changes. The "severe service" change interval is now 25,000 miles...this blows my mind.

Also don't forget when Ford put the 7.3 in trucks, CG, CH and CF were all current oil standards...so oil has come a long way. Also International recommends a 10k interval on the T444e, only a 2-3 quart difference between a PSD and a T444e.

I haven't owned the truck long. 109k miles currently on my 2002 PSD.
My first oil change using Shell Rotella 15/40 for 5k miles sent a sample to Blackstone and came back with excellent results. They said I could go longer.
At that oil change, I switched to Rotella T6 syn 5/40. Will probably go at least 6k miles or longer on this go round with the synthetic.
I only put about 6k miles a year on the truck towing an open trailer and my Miata race car to events.

With help from Blackstone Labs I am now going 12k miles or every two years on Delo 400 and a Motorcraft filter. It all started after a 10k road trip without an oil change and the results I got back from Blackstone were encouraging telling me I could go 12k on the oil. Well in one year of living in small town Alaska, I only went 6k and changed the oil for the hell of it. Just got the lab results and I was told I can go up to 2 years on the oil or 12k miles. They also told me I may be showing early signs of a head gasket leak.
If nothing else, blackstone labs have been worth every bit of the 25.00 per oil change in saving me a lot of $$$. I have to post a big update on my Mugly thread sometime but I will be sure to include the results from these oil samples.

Do the same rules apply as for a gasoline vehicle? Or is diesel different?

I too change mine once a year with about 9k on it with amsoil and was told by a diesel mechanic that I should use regular delo or equivalent every 3-5k because amsoil foams up and not good for diesels. I am going to check mine with blackstone this time around

Ya I suppose I need to send in for analysis to get an exact answer. I use Blackstone often for my other rides. This is my first diesel and I dont know how diesel fuel leakage past o-rings effects engine oil.
Gasoline is obviously very destructive to engine oil properties.
Same for diesel fuel?
I would never wait a year to change oil in a gas engine, but then again, they dont take 15 quarts of engine oil...

I would think the oil could last 2 years, but I would probably at least change the filter once a year. I would think maybe the filter media inside could start to deteriorate after sitting for a long period of time without having anything run through it. But I have no idea here, Im just throwing this out there.
