Well, since it's just rebuilt I'd go with a regular diesel motor oil. The grade depends on how cold your winters are. After the engine is broken in I use Rotella 0w40 synthetic.

I live in central Alaska and run delo 400 15w-40 year round, I have a block heater and 150W of oil pan heaters though. I wouldn't run very thin oil in Texas.

if you installed new rings, then dont use synthetic as stated above. you should even give it a good 10'000km's to seat the rings... then switch on over to synthetic for the life of the motor and it should last a good long time.
make sure the diesel oil is rated CF (CD is the old standard for turbodiesels)

Just tonight, I was in Walmart and was going to get a 2.5 gallon container of 15/40 Rotella. Then I saw the price on 15/40 Motorcraft CJ rated oil. It was $10.68 for 5 quarts. The Rotella was an even $26.00 for 2.5 gallons.
I decided to put my "usual" back on the shelf and go with several containers of the Ford Motorcraft. I believe it is probably good oil...better price right at the moment. This would suit you well.

Like everyone said, if you did your rings, use regular oil with a CF rating - like a 10w-40 for your first 2 oil changes - about 10K km. Then go with a full synthetic. You could start with full synthetic like Mobil One, but if you have fresh rings they will take for ever to seat and you'll be burning quite a bit of motor oil for your first 50k km - maybe a quart every 2k km. - Been there, done that - expensive lesson.

I think in the"C" rated oil, the -4 rating is for 4 stroke applications. The current -4 rating is CI-4. Rotella 15W40 would be a good choice.

Tyler should add that oil guide to the FAQ section that he's doing!

I know there are certain break-in additives you want in your oil on gas cars, i'm not sure for diesels. There was a special lube I had to put on my new cam for break-in as well.
Also, what all was done? What oiled parts are new?

The cam lube for a new cam is because it is under a very high psi and will be mostly dry on initial startup.
The CD-4 rating was among other things for soot suspension. Mobil 1 does not have this and this is why it can't be used long term in a PowerStroke diesel - their injectors are powered by engine oil pressure and fired via a 110v solenoid. This long device has close tolerances that become plugged with soot if the oil doesn't have CD-4 Mobil's industrial synthetic oil - Delvac 1 has this CD-4 rating.
