Well, I've been running different synthetics of different weights in my 08 wrangler since new to see what would get rid of or reduce my lifter tick (chrysler wouldn't do anything about it) and until now, Pennzoil Ultra 5w-20 was the only one that almost eliminated it. It took care of it until I was close to the end of my OCI, then I started hearing the tick again. I had decided to switch to conventional and see how that worked. I was running Havoline 5w-20 for about 900miles when I realized I left a breather hose off, allowing the engine to ingest unfiltered air, so I immediatly changed oil and tryed Wolf's Head 5w-20. Well, so far so good, I've got 400miles on this oil so far and no noise at all. I'm pretty pleased with this stuff. I also have no lifter noise at start up in the morning from the lifter s bleeding down like I did with alot of the other oils I've tryed.

Wolf's Head is supposed to be a pretty good lube. Good to hear it is working out so far. You might want to do a used oil analysis to check how the engine is wearing. Blackstone does a particle count for $10 extra so it may be a good idea to invest in that to see where your engine stands. I know it isn't the total diagnostic tool for an engine but it will give you a picture. BTW: I am sure you know all of this stuff, so don't think I am acting like I know more than you. Just a suggestion.
The get a lifter "rattle" at start up sometimes with certain oils after it has sat for a long time, from the lifters draining down. These engines also have problems with the ADBV's on certain filters also, Mobil 1 filters imparticular almost always drain down over night, but I've been running the Motorcraft FL-400s and havn't had a problem with oil pressure at start up.
As for my lifter "tick" that is there all the time. Its had it from about 600miles till now (38,000miles). Certain oil's just mask the noise better than others. I've had it to the dealer twice for it and chrysler told the dealer them selves that unless it gets anyworse they aren't gonna do anything about it. My jeep has the lifetime powertrain warranty on it, so I'm not gonna worry about it. It hasn't worsened any.

And I know its just cheap lifters causing the issue. My buddy and I pulled the heads off his mom's 05 Caravan 3.8 to replace lifters because her tick had gotten much worse than mine. We found several lifters where the piston inside them would not return all the way to the top of the lifter, against the retaining clip. We didn't bother taking one apart, but I'm guessing there is a spring inside there and they were either broken or just weakened. I've heard of lots of people with the Dodge Caravans having the issue with lifter tick, and the Jeeps don't seem to be much different at this point. I'm just happy I got one of the ones that doesn't have the oil usage problem (knock on wood
)
)My 4.7 is very picky about filters. Purolator filters give me a start up tick, Wix does not. I believe it has to do with type of spring in the filter. Experiment with different filter.
I've experimented with different filters. The lifter tick I have at all times isn't a result of the filter though. I've experienced a bottom end rattle at start up from using the wrong filters though. Believe it or not, Fram's seem to never do it, Purolator Classics seem ok so far, Purolator PureOnes have done it to me a couple times, as have Amsoil filters, and Motorcrafts havn't given me any issues yet which is what I've been using.
