Which engine oil

I am coming up on my first oil change for my CRD. Any suggestions on which oil is best for this engine? I will be using the Liberty mostly around town with occasional trips offroad and maybe some long highway trips. I have seen Mobil-1 mentioned and Castrol Edge but don't know much about either.

I choose shell rotella t6 5w30. Many on here use that or Mobile 1 turbo diesel truck . Then there is mobile 0w40 the owners manual suggests either weight. Just be sure its full synthetic

From what I understand Mobil 1 0w40 isn't a good diesel oil. It is an API CF oil.
CF standard was Introduced in 1994. For off-road, indirect injected (ours are direct injected btw)
and other diesel engines including those using fuel with over 0.5% weight sulfur. I don't think this oil is rated for EGR use but I could be wrong. I have used this oil before, not in my liberty, but in my snowthrower ;-)

Mobil 1 5w40: Meets CJ-4, CI-4, and CH-4 which are designed for EGR turbocharged high revving diesels that are direct injected.

Rotella T6 is 5W-40 go look for yourselves :BANANA:

Synthetic Rotella, in the blue bottle has always been 5-40 :SOMBRERO:

And if your curious, look in the FSM for what to use in the EXPORT CRD's with the same engine :lol:

Checked out the autoparts stores and other outlets and it looks like Rottella T6 is the only oil available without special order. Walmart carries it as a regular item. Price isn't to bad either, $19.50/gal and $6 and change for a quart. Makes the decision pretty easy. :idea:

The Wallyworld by me never carries the T6 0w or 5w :banghead:

I can get the 10w all day long.

Rotella T6 all the way...

I won't run a 0W40 oil in my Jeep when it's 90 degrees outside. That's asking for trouble. Not to mention, it's $42 for 6 qts. versus $22 for 6 qts. of Rotella.

Mobil 1 5W40. Walmart always carries it it my area.

I typed the weight of t6 incorrectly it is 5w40. My local Wal-Mart has it for $19 or $19.50 all the time they do keep changing the price. They also have mobile one 5w40 turbo diesel truck for $23.99 I have not found the 0w40 any places but advance auto and pep boys both at $8 a quart. So the T6 is an easy choice unless you feel you have a need to go with amsoil like a few guys here. Amsoil to me seems expensive.

Amsoil European Diesel oil. Amsoil EAA series oil filter as well.

It seems to vary widley what oil Wal-Mart stores carry in my area. The store I visit the most rarley has Mobil diesel truck oil and only has rotella T6 about half the time.

But two stores about 6 miles away in oppiset directions almost always has T6 and Mobil diesel truck oil :banghead:

But those two stores are not near other stores I frequent :ALONE:

So a special trip just for oil :5SHOTS:
