Royal Purple 5W30 Full Synthetic Motor Oil
Cons: Finding 6 quarts in one location!
Recommended? Yes

Comments: I had been running Mobil 1 with pretty good success. Decided to swap out to RP because of all the good things I kept hearing.

I had been running Mobil 1 in the engine, diff's, trans (till I read Stu's comments at www.stu-offroad.com about the GL-5 misprint for the AX-15). When I switched, I went to RP in EVERYTHING. Specifically with the engine oil I've noticed a little more valve tap. MPG is comparable to what I had before...not worse. This might work better for someone else. I'll probably go back to running Mobil 1 or try Redline.

Comments: I changed over to RP from Mobil one about a year ago after I heard Mobil 1 was no longer a true "full-synthetic" (not sure if that is true or not). I run about 8-10k change intervals and couldn't be happier with RP.

Comments: The XJ is old. So I splurge a bit on the oil, its the engine's blood. Just need to shop around for some deals to find it a bit cheaper.

Royal Purple 5W30 Full Synthetic Motor Oil
Pros: Purple when first put in. Full Synthetic.
Cons: Expensive. I cannot get it locally.
Recommended? Yes

Comments: Seems to be a good quality oil. I've heard good reviews.

We'll see how it looks when I change it. It also seemed to quiet down the 4.0 just a little.
