Buy filters from the folks who actually make their own...Wix.
Or from a company who has to stand behind a 36,000 mile or more warranty on their engines...Mopar.
Wix is good and they are made in my area of NC. I have a friend who worked there as a QA manager. They manufacture for many brands and private label companies. Fram is the only manufacture that I am aware of that has had catastrophic failures (and that has been over rated).

Champion Labs will build filters for anyone, to any specs it seems, so they can slap a name on them. STP for example.
OTOH, Champon Labs makes Mopar, to Mopar's specs.
I guess to be safe, I lean toward Wix or Mopar. They have a vested interest.

dang, I wish other questions i ask would get this much attention haha. I stick with the napa gold filters for the wifes grand, and have switched to them on my xj. I was just wondering about the silvers because like someone pointed out, you pretty much get them free with some of napas oil change specials. Right now it is 5 qts of valvoline, reg or high mileage and a silver filter for 20.99. a pretty good deal if the filter is good. shoot, shouldnt have mentioned oil brand, now all hell is going to break loose :P

Interesting you should bring this up.
Keep in mind that the factory is warrantying those same engines for 50,000 plus miles..
Also, when I had my fleet of trucks we did oil analysis every oil change from when they were new.
Found out the 7500 mile oil change interval was too short and we SAFELY ran to 10,000 miles with room to spare.
Not advocating this to the general public, but this 3000 mile oil change stuff is just to fleece the general public and get a chance to get them in the door, car up on the rack, and sell them more stuff.

I was advised to change every 2000 mi. or weekly for most of the smaller trucks running Denver metro and the Eastern Slope. All my oil was purchased by the drum and had a WIX Fleet vender in the area so used them there also, my oil Rotella T.
I don't know about others XJ's but I would have to consider the way I use mine as severe duty, would you not agree? Low RPM's, Idling, Dusty, some winching. I'm new to Jeeps but not upkeep on cars, trucks and race cars. But I need help everyday on my XJ as I bring it along to where I want it to be as far as upgrades and welcome any input.
Most name brand (I said most) filters have similar flow rates and filtration effectiveness. The higher quality ones are built for high mileage so they contain silicon gaskets vs rubber, high pressure release valves along with the anti-drain back valve. You can't have your cake and eat it too,there is a fine balance point between filtration (micron size) and flow restriction.
If you change oil and filter every 3500 miles then the NAPA silver makes good economic sense.

I am the same way as you and I have been driving since I was 15 and now I'm 50. Many have told me the same thing and I keep driving my vehicles while they have to rebuild there engines. Better safe then sorry.

RED4DR: I wasn't addressing you directly. I was basically referring to some of the previous posts in this thread, and many previous threads, about how ridiculous people can be by refusing to buy a quality filter.

Vehicle usage is a large factor in how often oil needs to be changed. Lots of cold starts, short trip driving, idling, and driving in dusty areas are factors that are going to require more frequent oil changes than someone who drives mostly long distance on the highway.
There are those that say they change their oil every 3000 miles and their engines are in good working order with 300,000 miles. There are others who use high quality synthetics and change every 10000-15000 miles and also have good working engines with 300,000 miles. There are still others who use synthetics and bypass filtration and change their oil every 50,000 miles and have good working engines with lots of miles...
One size does not fit all, and personal preferences are a factor. Some people like to change their oil all the time and others don't. The only real issue is when people who don't like to change their oil drive it too long for their operating conditions.

Chrysler bumped it up to 2500-3000 back around 1938. The others followed shortly after and despite all the improvements in engines and oil additives, that's right where it stayed until automakers started installing Oil life monitoring systems.
DW's new Impala just crossed 8K miles and it's still at 35% life. I'll probably change it this weekend.

Wife's '01 Cadillac Seville STS typically goes about 10,000 miles before oil life monitor says change it.
The computer monitors engine operating temperature and crankshaft revolutions to determine when to change the oil.
I change it when about 8-15% remains.
