What is the part number of the WIX filter for the 3.8? I know, the store can look it up but if we have the number already and the parts guy "accidentally" gives us the wrong one, we'll know.

Since I see others with clatter from the Mobil1 filter, then I can only say DO NOT use Mobil1 filters on your vehicle!!!!
Our engines were designed to have the anti-drain valve keep oil up in the valvetrain and not drain down into the pan. Starving the valvetrain of oil, if only for a few seconds, is VERY bad for the engine.
I used only Syntec in the Probe GT I bought new in '93. I became a Mobil1 oil supporter after reading all the positive comments (and outcomes) on Ford truck forums.
Filters? I'd only choose PureOne or Motorcraft. I would ALWAYS stay away from Fram and will now add Mobil1 to that AVOID list.

Heres a test you can perform on your Jk in regards to oil starvation. Turn your key to the on position and wait for your oil indicator light to go out. Start your Jeep and watch your console. If the oil indicator light turns on, even for a split second....oil starvation due to anti drain back failure. If it stays off you're good. As I said the Wix oil filter takes a few days to drain back, the others drain back usually within 8 to 10 hours and Fram retains the oil.
Trust me ....I don't want to believe it myself but I'm just sharing my test results.
Mopar - Drain back 8 hours.
K&N - Drain back 3 hours
Mobil1 - Drain back 8 hours
Motorcraft - Untested
Wix - Drain back 2-3 Days
Fram - No Drain back.
Whats unusual is that I had no issues with the original Mopar factory oil filter. My issue started after my first oil change with a Mopar oil filter.......and so the tests began.

Oil filters are like women
Everybody likes a different type! My two cents worth about oil filters ( being employed in the automotive industry for 35 years) is that take paint remover to any number of oil filters and you could not tell any other difference in performance or feel. Some clatter on startup, some don't. It's a quality control issue, not a design issue. ALL filters operate on the same design, some have an extra layer of paper in the filter, some have a larger or smaller drainback valve. The most popular have shiny paint and golden decals.
What a crock! The Purolator filters for $1.88 at PEP BOYS work as good on a short interval oil change as ANYTHING else. Fram base oil filters are as good as ANY other brand out there. Period. I'm not blowing smoke here, since 1988 I have put 933,000 miles on my family cars- olds,pont,chev,jeep,etc. 10W30 Pennzoil Dyno and the cheapest Purolator or Fram filter available every 3000 miles. Absolutely NO engine issues whatsoever- NONE. NONE.....Never had the first clatter on startup either. Sorry if I pissed off any Golden decal fans out thereGosh I can't stop laughing....Golden decals......I'm screamin'!

Isn't it odd that the most expensive oil filters perform the worst? Its like the manufacturers over think it.

I am going to try one of these. It can't be any worse than a Fram filter. But if I was buying throw away filters, like I used to, I think the Bosch ones work excellent. http://www.4wheelparts.com/prodDetai...eep-parts=true
