Let's not confust the Mobil 1 products though. The new M1 T&SUV is a 5w30 oil and is not Diesel rated. There is also another new M1 product called M1 Turbo Diesel Truck...which of course is a diesel rated oil in a 5w40 weight. The old T&SUV 5w40 is a discontinued product.

Also, the new M1 Turbo Diesel Truck 5w40 is the same exact oil as Mobil Delvac 1 5w40.

Actually it was just repackaged and not discontinued, and we from the TDI forum have known for years now that Mobil D1 and T & SUV are the same oil. I'm not sure about the 5w-30 T & SUV oil as I never checked it out because it does't meet the spec's for anything that I currently own.

I hope that with advent of ULSD fuel I could run the 0w-40 M1 that I also use in my Magnum because of the high shear requirements of chain & gears of the MB designed engine in the Magnum. It is a PIA to have 2 different oils on the shelf and having to buy them at different stores. The only reason for running it in the CRD is the soot additive package it lot stronger, because I want to be able to do 10k mile oil changes. I hope that oil testing will let show I can, but it all depends on ULSD and how well the EGR works or FUBARs the works on a regular basis. Actually I could probably use the 5w-40 T&SUV oil in the Magnum as it is close to the same as shear properties goes, but then close only counts in horse shoe's and the Atomic bombs.

The "C" in the CH-4/CI-4/CI-4+/CJ-4 actually stands for "compression", vice "commercial". C - compression (as in compression ignition), S - spark (ignition). Other than that, good summary of the oils.

And I like to add that in Europe Group 6 is available and one of a few oils is ELf,Pentosen and a few others made in Germany,France.
Here is the web site www.elfusa.com

Well, according to M1, the Truck & SUV 5w40 has been discontinued. Note that they use the phrase "DISCONTINUED".

http://www.mobil.com/USA-English/Lubes/ ... _5W-40.asp

Also note the specs and approvals. T&SUV 5w40 did not meet the CI-4+, which the M1 TDT is approved for. The typical properties are the same for both products though.

Let's not get into oil wars!! The Wally World oil Rotella T is just fine for 8k oil changes. If you like the 0-40 Mobil 1 will be fine to ..Me I use the Rotella T for price and value.

Did I ever say it wasn't for a Diesel? No, I just said it was discontinued.

I DID say the CURRENT M1 T&SUV (which is a 5w30 weight for gasoline engines only) is not for Diesels.

Basically, any T&SUV 5w40 that you find on the shelves is just left-over stock as M1 does not make this product any more. Their current products are listed in my previous post with the three links on them. The reason why I said something in the first place is because it is senseless to tell someone to look for a product that is discontinued. Second, some may get confused when they see T&SUV on the shelf and they may not notice that the new product is a 5w30 and meant for gasoline engines only.

So my statement stand correct, M1 T&SUV (as it is currently produced in a 5w30) is NOT for Diesel engines. The discontinued T&SUV is acceptable for Diesel engines if you can find whatever is left on store shelves.

oldnavy is probably correct that the OLD T&SUV and the NEW TDT 5w40 weight oils are probably the same thing, based on the typical properties listed on the M1 website being exactly the same.

They still make it.

oldnavy · **Posted:** Sat Dec 23, 2006 8:26 pm

Yes I remember when Mobil did the change of names. When I called them about the change over about this time a year ago, I was told about the name change and that T&SUV was being replaced by TDT and was just a repackaging then for marketing and the oils would be the same, he started to tell me about the 5w-30 T&SUV oil but I told him I didn't own a vehicle that was suitable for the product.

I think I slipped up and didn't make the connection NBS was talking about, added with a senior moment while grandson was beating up on grandpa. Anyway I have a qt of what I was calling T&SV in garage but it is TDT 5w-40 in truth.

I sure miss the VW oil wars. :roll:

Having just gone to their site all they have under "truck and suv" is the 5-30 that they say is not recommended for diesels :roll:

They say to use "Mobil One Turbo Diesel Truck 5-40" :!:

Now we all suspect that both what your talking about and the turbo Diesel Truck 5-40 is the Delvac 1 oil repackaged :idea:

So I think they really don't make what your talking about anymore

But Truck and SUV is just for gasoline engines.

The old M1 T&SUV 5w-40 & Delvac 1 5w-40 (yes the two oils were the same stuff) oil is the exact same oil as the new TDT 5w-40 oil for diesels, just has a different package name and a price increase. Mobil is using the T&SUV 5w-30 now for gassers and it may be a new oil however I haven't checked that out.

It kind of makes more sense that they did this if you think about it. Most of the SUVs and Trucks in the US are Gassers and call for a 30 weight oil, so a lot of people probably didn't buy the 5w40 because their owners manual called for a 30 weight. So now, M1 gets the best of both worlds...they have a Diesel oil that is specifically marketed for Diesel applications and a Truck&SUV oil that is going to meet the majority of mfr requirements for Trucks&SUVs with gas engines.

Now wasn't this fun? Sure, not nearly as fun as the battles over 505.01, 506.01, etc. etc. on the TDI forums...but still fun

Here is the link to the source that Got Diesel used for his posting and it is copyrighted and will require premission to reprint here at LOST Forum. I haven't decided as yet to seek permission and most likely will not unless there is a lot of request for it to be posted in full here.

I will most likely put this over in the general FAQ section and delete the Rotella postings all together later today or tomorrow.

Don't you know that 507 is even better!!!1111!!! Jeez, what an ignor-a-moose! You're probably the guy who buys Motul instead of Elf...!

But, yeah, I totally agree. Its nice that the Common Rail doesn't need any special oil, but scary how lax DC has been about it. At least with VW we knew specifically the factory recommendations!

LOL.....actually

Before my TDI was wrecked...I used Elf Evolution CRV 0w30 506.01 specification

Or at least that has always been my understanding. It is probably one of the strongest Grp. lll oils available and for normal OCI's it is more than adequate. I am looking forward to an analysis on it so that I can see if a longer drain is in order or not. I also have a large stash of CH-4 D1 kicking around that I got cheaply.

It also appears that Mobil may have done a back flip on some of it's Mobil 1 oils. They always claimed them to be Grp. lV's but I have seen some people claiming that they may have snuck some Grp. lll's in there as 'synthetics'... Time will tell.

John.

no-blue-screen · **Posted:** Tue Jan 02, 2007 7:31 pm

I suspect the regular Mobil 1 synthetics are group III base, and the extended performance line is probably group IV. This is pure speculation though, as I have no proof to backup this statement.

DnA Diesel · **Posted:** Wed Jan 03, 2007 5:10 pm

IIRC,

Mobil 1 is GpIII.

Mobil 1 TDT (TurboDiesel Truck...what used to be Delvac 1) is a Gp IV.
