4.0 i6
189,054 miles

5w-50 Castrol Syntec 2k to 3k miles depending on driving conditions and oil clarity.
Slick 50 oil treatment around every 10 oil changes, Engine. 6oz per 1qt oil. Every couple years front and rear diff’s.

Original motor as far as I can tell no internal work done yet.

Changed all the fluids, tie rod ends, cleaned up the dull head lights and replaced the cloth seats with power leather seats.
Replaced the water pump, thermostat, flushed the system and put new coolant in it when I first bought it.
New hood shocks, rear window and rear hatch shocks. Installed new brakes and rotors, front and rear. September last year.
4” RCX short arm kit last year.
I rebuilt the 42re about 9 months ago in my garage here in Kansas City, was at 160922 miles at that time.
Replaced the steering gear box in AutoZone parking lot Grand JCT, Colorado in June this year
Replaced rear wheel seals and bearings in Porum, Oklahoma in July.

For maintenance I’m probably a 3.2 or slightly higher. I check all the fluids under the hood every time I fill up with gas.
I worked for several repair shops over the years and even worked for Chevrolet for 7 years. I was a mechanic most of my life and even before I graduated from High School.
Have had the chance to see the performance of different fluids first hand and the effects of different maintenance habits.
Remember your recommended maintenance is just basic best guess that the manufacturer has provided. If I notice anything that does not look exactly as it should I will not wait till the recommended interval before changing it.

I don’t look as much at the chemical properties of any of the fluids I use, but more about how well I have seen them actually perform in the real world.

2003 Overland
4.7 HO
No major failures at all
Using either Mobil 1 High Mileage or Rotella T5 10W-30, but might change depending on my next UOA.
I'm a 3+ on the maintenance scale. That said, I rarely have to do any work on my WJ, it's been very reliable and the scheduled maintenance intervals require me to do most all fluids at once every 2 years.

2003 4.7 Non-HO, NV247, just turned over 128k yesterday. My wife bought it back in 2006 with just over 50k on it.

For a long time we ran Valvoline 5W-30 Synthetic and Wix oil filters. We recently switched to Shell Rotella T5 5W-40 about 10,000 miles ago, still running Wix oil filters. Due to my wife's commute, which involves stop and go traffic and not a lot of engine running time we run a 4500 mile OCI.

No internal engine failures at this time. I have replaced the water pump 3 times, PS pump 2 times, thermostat, thermostat housing, valve cover gaskets, serpentine belt, TPS, and IAC. I do need to replace the timing cover seal and oil pan gasket, possibly the RMS as well, but I'm hoping its just the pan.

Spark plugs, PS fluid, differentials, coolant are all changed at the recommended intervals. I change the t-case fluid every other year, which might be overkill, but so far the NV427 is still happy.

I'd rate myself a 2.5.

Hers: '03 WJ 4.7 Laredo- Some more stuff

2004 Columbia Edition
Purchased May 2011 with 78k miles/Currently shows 97k miles
4.7 HO/545RFE/247 TC
- Oil changes at 5k miles using Napa Gold filter and Napa Full Synth oil
-Added PML transmission pan and changed ATF (Mopar 7176 and filters) at 80K with the next change on tap at 100k then at 25k mile intervals after that.
- New radiator/hoses/antifreeze/plugs/fuel filter at 80k,
- power steering pump at 95k
- Napa Gold air filter 1x per year (drive on gravel roads)

Still need to change TCase and diffs and plan to do at 100k. I also want to install an aux transmission cooler but have not made time to do it. I am probably a 2.5 when it comes to maintenance but do not always follow the manual. I do things at intervals that I remember like oil changes on the 5's and major fluid changes on the 25's as I drive 25k-30k miles or more a year.

'03 Laredo w/ the 4.0 176K, I'm assuming it's the original engine. I doubt the original trans would have made it this far, but I have no idea if it's been rebuilt/replaced. Everything under the hood and body looks clean and original, so who knows....

I just got it 4 months ago, so I have no idea of what was used for oil or how often it was changed. I can say this; when I replaced the valve cover gasket, there was absolutely no carbon build up or sludge anywhere on the head.

I did an engine flush using BG chemicals 'engine flush'. Everything came out looking good, no nasty gunk or sludge. I used Pennzoil high-mileage oil and a Mopar oil filter. I plan on doing 5K intervals for the engine oil changes.

I've had to change the PCM, the oil pan gasket, V/C gasket, both idler wheels for the drive belt. I replaced the fuel filter ( Wix), air filter (Wix) and recently, the spark plugs. Those last pieces all seemed to be original parts, so I wonder if the poor Jeep was ever maintained.

I also replaced both axles with ones from an '04 Overland, they only had 68K on them, it was a lot cheaper than rebuilding the original ones plus now I have Vari-lok front and rear plus a D44a in the back.

I think I'm on top of all of the immediate maintenance needs for a while, I hope I can just drive the darn thing without any headaches.

I'm a 3+ for maintenance. I don't want to work on this thing non-stop, and I'm not out looking for every little tiny items that may show wear, but when there's something that needs attention, I'll go at it full bore and only use good quality, brand name parts. My motto: do it right once and be done with it.
