Did you switch back to Castrol High Mileage ? Noise quiet down ?

sorry guys my update is since i have two jeeps and alternate back and forth . Along with barely driving them since i work local. my twice a year oil changes are getting pushed to the spring it looks like. now even more so with a synthetic in there... lets keep this going guys. lets us know what your using and when you switch if anything changes noise related etc. i still might change the oil in the 99 in another month we will see.

Castrol HM is the thickest HM oil available that I know of. The 10w30 is identical to the Rotella in actual "thickness". Now that it's getting cold I'd suggest the Castrol HM in 5w30. It is actually thicker than most generic 10w30's but it has a higher Viscosity Index so it flows better, and of course it's a bit thinner than the Castrol HM 10w30.

I've been running the Castrol GTX HM in 5w30 since late July, it's been really quiet and it also seems to clean well. I'm actually going to run a blend of Castrol HM 5w20/5w30 over the winter (it will still be as thick as normal 5w30's) then switch back to the straight 5w30 in the spring. The Castrol has been as quiet as the Pennzoil has been for me, and I've tried a lot of oils.

I'll be doing UOA's on it also, Chris please be sure to post yours!

Rotella would work but it's just not a great match for the 4.7. Something like Maxlife in 5w30 would be a much better pick for that engine.

For fighting ticks, thinner not thicker is your friend. The Maxlife flows better and is thinner than most other high mileage oils, and has a great add pack plus a history of producing very low wear in engines.

bought my castrol high mileage 10w-30 tonight i was looking at the valvoline high mileage . wanted to buy it but they only had the 5 qt and no single quart. i also bought a qt of lucas heavy duty oil stabilizer and debating if i should put this in place of of the one qt of with the castrol .im tired and after i left i realized i could have bought the valvoline 5qt and the lucas one qt lol. im going back to the castrol or maybe the maxlife lol to see if the tapping knocking noise goes away

Forget about the Lucas oil stabilizer. All you get is about a 250W oil with zero additives at all. You would be much better served with a quart of anything else short of cat urine.

KayCee - I'd be really interested to see your UOAs with Castrol HM. With its low-zinc formula it will be interesting to see how it treats you in the 4.0.

I'm running Rotella T5 in the 4.7HO at the moment. I'm interested to see how it does compared to the M1HM I ran for 2 years. Also interested in possibly going to T6 5W-40 since I have so many cold starts and short drives. Between the T5 and M1HM, I get more zinc and better TBN than the M1 but less moly. Much more calcium for cleaning.

Have you looked at Quaker State Defy? Cheap and loads of Zinc. My 4.0 seems to like it better than Mobil 1 HM.

I still have my sample to send in to Blackstone Labs of the Rotella T5 10W-30 that was used and abused more than I like. I used to be a 3K OCI kind of guy but on the T5, I *think* I ran it 6K - 6.5K (I need to check my notes - it was close to that.). I'm excited to see how it stood up to that length of time with 80% city driving, ~20 minutes per trip. That many miles makes me nervous but then again, I'm used to changing early and often. I'll try to send that out this weekend and see how it stood up!

Wow, talk about perfect timing! I bought my '99 just over a month ago. It has the 4.0 in it, and right at 225,000 miles on it...the PO gave me EVERY SINGLE Receipt for ANYTHING and EVERYTHING ever done to the Jeep. Every oil change, tire rotation, brakes, tune ups, belts, hoses, etc...Jeep currently has no leaks, but the engine is filthy! Have really debated on degreasing it, but don't want to wash anything away that may be "holding" stuff in. It is time for the oil change (only reason I didn't when I bought it, was because he had just had it changed before I bought it, and it looked clean and smelled fine, when Checked). The PO took it to Xpress Lube and has kept Valvoline HM in it...runs great, doesn't tick or knock...should I stay with that? I change my own oil and filter, and will probably go with a Purolator Pure One Oil filter (Yellow One).

I have been looking into what oil is/will be best for the ole girl, and this discussion popped back up in the thread. I've looked at the Castrol GTX High Milage, Mobil1, Valvoline HM, and been looking at the Rotella...Just need input!

I drive my Jeep Daily, back and forth to work (10 miles round trip), then to practice (30-40 miles round trip), and running errands (100 miles a week)...not a whole lot of stop-start...usually upon arriving at work, practice, errands, it is sitting for 3-6 hours...

I would run the Valvoline Maxlife 10w-30 to me its the best oil for the 4.0L it has 2100 PPM of calcium,490ppm of sodium as well as 760 phos 840 zinc and 160 of moly. You really don't need 1,000 plus of ZDDP in the stock Jeep 4.0L it has weak springs and 2000 and newer 4.0's have very conservative cams even though they are flat tappet. If you were running a stroker with a mild to wild cam I would say something like Valvoline VR1 but, to run that in stock is just overkill and doesn't provide any benefit really. Use the Valvoline Maxlife in confidence.

I have a 98 with 260k and it has only had regular castrol the first 150k then the maxlife life the other 110k with no problems. People stress to much about ZDDP and truth be known 1992 ZDDP was only at 1200 and by 1996 was only at 900 to 1,000 so if it were that big of deal we would see several thousand 4.0s with problems. Not the case.

I'll be sure to post, it'll be a while because the first UOA will be on the second run for the best evaluation, but I'm planning on doing several in a row as well.

Current first fill is at 4,500 and still very quiet, I've had "quiet" oils get to clanging after a few thousand miles before, but the Castrol hasn't done that.

I agree with bilzcat forget the Lucas, it won't do a thing for you except perhaps create more cold start up noise.

Since your fighting a tick I'd suggest you try the Maxlife, it's thinner than the Castrol and thin is your friend when it comes to ticks. But the Maxlife was not very quiet in my 4.0, YMMV.
