Do Mobil 1 filters have anti-drain valve?
I recently decided to change to sythetic oil
made by mobil 1. However, my question is
about the filter. Do all the Mobil 1 filters
have the anti- drain back valve? Are they
designated as anti-drain back in any way?

To the best of my knowledge they do have the anti-drainback valve. I have used them on all of my vehicles for many years now, and they all start very quiet. My truck makes no loud ticking/tapping when starting up.

Looking at the top of the filter, you will see a large hole in the center. Around that hole you will see a circle of smaller holes. Under those holes you should see a rubber (can be black, orange or some other color) washer that covers all of the holes from the bottom. That's the anti-drain back valve. Fact is, I haven't seen any oil filters lately that don't have one.
