It does state on Page 317 of the Jeep Grand Cherokee Operating Information book "...such as...Shell Helix or equivalent. "
It's all too hard..I'll just live in ignorance.
rather than clog up this thread - here's a link from some time back when a few of us early CRD owners were first grappling with the fact that dealers were filling with any old "one size fits all" oil
CRD oil on special
and here's one of my posts from that thread (I was back and forward with emails to Shell TS Melb. and the date was 19/10/2012) - nothing has changed…
"Well the situation hasn't improved.
progress report from email received from Shell Technical Services today.......
It appears you bought old and new product formulations off the same shelf. The current (since Feb 2012) formulation for Helix Ultra Extra 5W-30 does not claim any formal ACEA specifications (including C2 & C3) or Chrysler MS-11106 specification (including some other OEM’s). There was a change from a formulation developed in XHVI (that carried an ACEA claim), to a new formulation in Yubase/PAO that uses a different additive.
At the moment, we don’t currently have a product on which we can claim Chrysler MS-11106.(To Claim MS-11106 you need to meet MB 229.51 + the TEOST test.)
If you require follow up information on your query, please quote the reference number for your case from the subject line of this email."
and my immediate return email.....
"Thank you for your reply….but I must say I am more confused and concerned than I previously was.
You noted "The current (since Feb 2012) formulation for Helix Ultra Extra 5W-30 does not claim any formal ACEA specifications (including C2 & C3) " and "you need to meet MB 229.51".
The apparently new stock container that I have is marked with ACEA C3 and MB 229.51 amongst a number of other manufacturer approvals. Your website product information for this oil confirms this. The Chrysler MS11106 being deleted is the only information that seems to be different from previous.
It seems your advice is in conflict with the container and website information - or am I missing something??
Can this oil be safely used in my 2012 CRD Jeep Grand Cherokee without compromising the engine or Chrysler warranty?
I would appreciate if you can clarify.
This is turning into much harder work than I anticipated."
Shell must have thought this was getting a bit hard as they never replied and I wrote them off as shonky, and changed to the Mobil product.
I care because with the EGR and issues with carbon build up in the intake system reported with other manufacturers vehicles, it is important to me that the oil I use doesn't create issues down the track.
Why would a dealer care? Profit is the motive.
