Welcome to the forums! Lots of good info here!

I've got a 6.0 (and am new to diesels) and after some reading here, I just use the Motorcraft...it's inexpensive and readily available everywhere.

Never switched to the synthetic oil here, but I've owned a 97 F250 7.3 that had like 275,000 miles on it, and now own a 2000 F250 7.3 with 155,000 miles on it. Always used Rotella, never had a problem!

I guess I never said which Rotella I've used. 15w40 every 5,000 miles. No problems ever!

I have used the Mobil Delvac 1 synthetic in all my trucks. Everything from my PSD to the Cat 3406's in the big trucks I used to own. In the long run, I found synthetic to be a cost savings in both fuel and maintenance versus mineral due to improved economy and extended drain intervals.

I run AMSoil Synthetics in all my cars and wouldn't run anything different. It is a bit more expensive, but results in less frequent oil changes and noticeable improvements in multiple areas. Just my opinion.
