Find a shop with a Bilstien engine flush machine. It'll flush everywhere
oil can go (using pressurized heated chemicals in a closed loop, from
the oil filler hole to the drain plug). When it's done fill with Mobil 1
which will clean out anything that's left, running synthetics will
basically eliminate sludge by keeping it from happening in the first place.

I'll chime in for a change. Frams are okay if you buy the Toughguard
models. The regular ones apparently are crap.

But the Jeep 4.0 (not sure about the 2.5) has the same problem as the
Mopar Slant Six. The filter is "upside down" and has a natural tendancy
to drain back the oil overnight, leading to a dry start in the morning
if the anti drainback valve fails.

I have lots more years experience with the Slant Six than the Jeep 4.0.
I know that the AC-Delco supposedly has a very good anti-drainback valve
design, but I have NEVER had one that kept oil in the filter overnight
after the first week or so. I stopped buying them about 7 years ago
specifically for this problem. I have experienced the same problem with
the regular Fram filters, but only twice. Perhaps AC has changed over
the years, but they lost my business. There's nothing worse than having
to pull a dripping filter a week after you thought you had finished the
nasty oily stuff for a while. Not to mention the $.

I now buy Purolater exclusively and have never had a problem.
Unfortunately, this has delayed a few oil changes as Pep Boys is the
only store that carrys them and they are usually out of the one for the
Jeep. I guess word got around.

Regards,

DAve

Yes for my Jeeps, I also use the blue Purolators (Premium?) oil filters and
I also have to stock up when I see them on Pep Boys shelves esp. if on sale!
AFAIK The standard Purolator and the Pep Boy "Pro-Line" are supposed to be
the same filters. ;-)

I have an 02 X, and it's filter is on the side of the block, not upside
down, just sideways like most other cars.
