what oil are you using?
when i bought my jeep the guy told me he used mobil one in my jeep. I did a oil change the other day and did not see the point of buying expensive oil if it leaks it lol. I always had the " lifter chatter" from time to time. seems now that i used 10w30 it chatters a little more offen. what oil do you all use to maybe improve the issue?

I use Royal Purple 10w-30, it costs alot more but I baby my XJ when it comes to fluids, plus I've tried it with that and Valvoline, it seems to run a little better with Royal Purple.

I put 5w20 in for the summer months and plain old 10w30 for the winter months. Better to have a thicker viscosity for those warm months.
I just use regular oil (no need to use an expensive synthetic on a 20yo vehicle)
I do add some form of additive (depending on what I find affordable at the time) like Slik50 or Wynn's.

I agree with bugsy, no sense in synthetic in a 20 year old half-wore-out truck.
Hijack: I see most of you folks are running 10w30. I usually run 10w40 Castrol in mine. Is the 10w30 better in a 4.0L?

The "no need to run synthetic" comments crack me up. The ABSOLUTELY, MOST IMPORTANT piece of maintenance you can do to your vehicle is oil. Do you HONESTLY think $21.99 for a gallon of synthetic is a lot? Im always blown away by those anti-synthetic comments. Synthetic oil is better, period, no denying it. Nobody will ever convince me that spending $21.99 on oil is an unnecessary expense, even if I had to do it once a month. And there is no way running conventional oil is better than synthetic for my Jeep.

Older 4.0's used 10w40. newer ones use 10w30.
I use the cheepest 10w30 at Walmart and a Fram filter every 3000 miles.
250k on my '88 before the body gave out.
239K on my '99. Quiet Strong running motor!
