If you really want a validated recommendation ,just "Search" JGDT40.
There are lots of Ford turbo diesel approved oils(like some grades of Rotella ) and their attraction is lack of foaming.But this is only significant if you operate at very high revs with the M96. They usually have good shear and thermal stability but JGDT40 outperforms them in most relevant specs. Given the vulnerabilities of the M96, why take a risk ? The slight premium for the best suited oil may be valuable piece of mind ?
Another consideration is that if you buy the JGDT40 from RND you can get a free UOA from an M96 expert. Now that IS significant imho.
