I ran it in my Liberty for 2 OCIs I think (maybe a third, don't remember). It's an oil leaker. I've also ran Maxlife in it. With the Castrol, the oil level wouldn't move for about 1000 miles into the OCI, then it would leak again. Maxlife I'm not even sure it's doing anything, so Castrol in my experience wins against Maxlife.
In my 96 Cherokee, I ran Maxlife in it when I got it and still got oil drips after a few changes. Started running Pennzoil HM in it and the drips stopped, at least enough to not hit the ground. I probably have to add about a quart every 2-3k for it, which I'm happy with.
One that I don't know about is Quaker State Defy. I'm guessing as a SOPUS oil it's like Pennzoil HM but I don't know.
