I have an older Jeep Wrangler with a 4.0 liter engine that I inherited from my great uncle. This weekend, I’ll be changing the oil in it for the first time. What’s the best oil filter for a Jeep 4.0?
Answer provided by
There are a LOT of fans of the Jeep 4.0 liter engine (which was sadly discontinued in 2006), so you’re lucky to get your hands on one!
The best oil filter for a Jeep 4.0 is certainly up for debate. Not every Jeep enthusiast agrees, but here are some honorable mentions across various Jeep discussion boards.
- Motorcraft FL1A
- Napa Gold
- Wix
- Mobil 1
Many Jeep owners swear by Wix and Napa Gold, but the other brands were also mentioned more than once. Now, be sure to consult your owner’s manual when selecting the precise filter size. Your model year, for example, will be important.
Whether you’re shopping for oil filters or oil changes, comparison shopping is a must. The same is true of shopping for car insurance.

Site says this Wix is a fit for XJ,
but it's clearly longer than my AC DElco PF13
Has anyone installed this Wix ?

It'll fit. That Wix is the same as a NAPA Gold 1085 which is for the 4.0 XJ.
I run a NAPA Gold 1515 which is 5.2" long. Use to run a NAPA Gold 1459 which is 7" long.

It looks like the
Wix is actually the normal length,
and that AC Delco was shorter than usual.

Wix 1085 or 1515 and be done with it. Napa and O'Reilly's carry them.
It's not like the 4.0 NEEDS more oil capacity!!!!

I've always ran with the Wix for full synth. filter since I run the T6... never had any issues. And seems to be decent quality for the price.
