which motor oils are rated CG-4/SH or higher?
Kenneth East
After being told by my Ford dealer that Mobil 1 can be used in my new
Powerstroke diesel, I see that the engine manual says that's not the
case. According to Mobil, Mobil 1 is rated SG/CD. The manual states
that Ford requires the use of CG-4/SH.
I've checked the local stores, and none carry any oils with that high
a rating. The next step is to start calling local oil distributors
(or perhaps the Navistar dealer) to see which oils actually meet that
rating. But before that I wanted to see if anyone on the net had
pointers.
I assume it will end up being some type of fleet/industrial oil
(e.g. Conoco Fleet 30). Overall, pretty disappointing. I had hoped
to be able to use a synthetic.
thanks,

Perhaps the info you got from Mobil is old. I have a bottle of Mobil 1
15W50 in front of me. It says
Exceeds API Service SH,SG/CC,CD
warranty requirements for gasoline
and diesel engines as well as CCMC
G-4/PD-2 European and Japanese
(JASO) engine oil requirements.
My guess is it's fine for your application.

Whatever literature you read about Mobil 1 was probably printed before
the SH standard came out. Mobil 1 is SH/G-4 rated. The print on a
bottle of 10W-30 in my room says so :-)

Yaakov,
My info came from the Mobil web site, what you have must be more
current/accurate. Even so, it is _not_ fine for my application. Just
because the can says it exceeds all warranty requirements doesn't make
it so. Ford/Navistar requires CG-4/SH. From what you write, Mobil 1
has the "SH" covered, but CC/CD is not equivalent to or "higher" than
the CG-4 rating. It makes the difference between having warranty
coverage and not having it.
Thanks for the followup.

I have never heard of a CG-4 standard. Perhaps Ford simply means the
European CCMC G-4 requirement. Mobil 1 meets CCMC G-4/G-5/PD-2.
Yakov didn't imply that CC/CD was equivalent to CG-4. He listed the
CMCC G-4 standard, which I bet Ford is referring to as CG-4. You
should of course call Ford or Mobil (800-ASK-MOBIL) to confirm both
notations refer to the same standard.

CG-4 is the current rating for many diesel engines (effective Jan 1996).
It replaces the older CF-4 spec. There should be no problem finding an oil
that meets this spec, try Caterpillar DEO, Mobil Delvac 1330, Texaco Ursa
Super Plus, Shell Rotella-T, Amsoil Marine; I think they all meet CG-4
spec. Look for CH-4 to appear soon. One thing I can say about this oil is
that it has 4 times the soot dispersing ability of the CF-4 oils and it is
designed for use with low sulfur fuels.

I called Mobil after getting the number from Adour above.
They confirmed that Mobil-1 does not meet API SH/CG-4. Mobil does
have a synthetic called Delvac-1, intended for large diesel trucks,
that carries the SH/CG-4 rating. They also said that G-4 is not the
same as CG-4.
I will call the major oil companies to find out their equivalent
products. Once I have the info, I'll post a summary back here.
And thanks to all the Amsoil distributors that were kind enough to
respond via email. From what they report, Amsoil has a synthetic with
the SH/CG-4 rating.

I've got a quart of Mobil 1 synthetic right in front of me which says on the label
that it exceeds API service SH,SG/CC,CD so it can indeed be used for engines rated for
the newest SH oil. I got it at Walmart here in Canada, perhaps the places you have been
looking in have older stock of Mobil 1 lying around.

Ken:
Have a Power Stroke myself. I don't use synthetic in it due to cost.
I change according to recommendation. I would not enxtend the oil
change interval in a diesel. Best oil to use, and one most of us PS
owners use, is Shell Rotella-T. Can get is at Sam's and Wall-Mart.

Dan

Ken, Mobil one SH is the same formula as Mobil one years back that was
SG, they didn't change it.
