It does have one Gil.

Or use 15-40 Rotella in my Ford 861D. It seems to work

I've never been a fan of oil change intervals that are that extended and I am certainly not a fan of expensive synthetic oil. But because of that expense I decided to use Blackstone lab's oil analysis reports to ensure that these extended intervals actually were valid.
