Your beloved rotella won't last anywhere near that unless you add a quart of stem cells.

 

I meant you could use whatever oil and go 200,000 miles but I think you could shoot for higher with a Rotella oil. But to each his own and there's plenty of good oils out there.

 

I changed the oil this weekend. Now I'm using Shell Rotella t5 synthetic blend 10W-30. It seemed to quiet the lifters down and the pressure is better. Thanks for the write-up Salad.

 

I changed the oil and filters in 3 vehicles (4.0 XJ,4.3 Blazer,5.2 Durango;all with around 145k miles on them) from AA oil and Fram to T6 and NAPA Gold. All picked up a noticeable increase in oil pressure at highway speeds and at idle. Not saying other oils (and filters) won't do it to.

 

I don't get what's with all the negativity in this thread. This is a good write-up with some valuable information. Someone has gone thru great lengths to find and present the information in a fashionable and enjoyable matter. This is just facts and numbers. Those who aren't subject to financial restraint and think the Delo or Rotella is for them, then by all means let them buy it. If one feels that the oil that is on special at walmart is fine for them, then to each their own. But i think we could keep the ignorance to a minimum, couldn't we?

 

This was a very informative read. I tried rotella maybe 2 years ago and my distributor quickly went bad. After that, i changed my dizzy and oil and things are good. I credited the increased wear to the rotella oil but maybe i was wrong? It could have been coincidence. I have since used 1 qt of rotella to 4 of other types of oil (including valvoline, quaker, etc).

 

CCanadian Tire stores have shell rotella on sale for $20 / 5L jug this week.

 

I would call that coincidence. It happens.

 

I tried Rotella a while back and my girlfriend at the time broke up with me, well it wasn't working out anyways.

 

Ever since I started using Rotella my exhaust fell off and I got a crack in my frame.

 

After quite a bit of reading, I'm considering taking the plunge soon into trying Rotella Oil in the jeep to see if a few things quiet down a little. I've been running Mobil 1 Synthetic 10W-30 with Mopar filter for the last couple changes (only had it 4 months).
Is my best bet to go with the Rotella T5 (10W-30 synthetic blend) or T6? I'm in Kansas and spring/summer is coming. Nothing too crazy temperature wise.

 

Oreilly's has T5 rotella 15w-40 on sale for 13.99 a gallon... not bad!

I replaced my oil pressure sensor and my oil pressure went up... now that I mention it, I replaced the coolant temperature sensor and my temperature went up... meh

Im too busy at the moment to hook independent gauges up to verify... sounds like a summer project..

 

As of two days ago I am running a dual oil pressure sensor setup, a put a t fitting in there and I have the (bad, but consistently bad) oil pressure sending unit and a mechanical gauge so I can compare the numbers. The oil pressure sending unit has some cracks in it that allow oil to seep through to the connector and it constantly reads 20-30 psi low because of this. Haven't ever seen a 97+ XJ that didn't have a broken factory oil pressure switch, lol

 

More pix, at cold idle. Mine hot idles at ~25-30 on the mechanical dial, and was always zero, check gauges on the dash

 

according to my gauge at present, I hot idle at 40 psi, and cruise the interstate at 60
