Yes, in fact the Millers 5w30 is all three.

However I said E6 limits the P to 800 ppm, whereas E7 and E9 have a higher limit. I believe most E7 / E9 HDEOs have about 1000-1200 ppm of P.

Exclusion of E6 certification means it will have higher P which is what I was trying to say. Perhaps I wasn't clear.

Tikka,

These guys do emissions intact tuning for the OM642 here in the states. They may be able to program a tune for you that throttles or shuts off EGR flow. They do extensive testing and R&D on their software, more so than most aftermarket tuners. This will reduce engine wear and improve economy/performance of your vehicle.

The oil does not show up on any lists as having actual approvals, at least not that I could find. If it is indeed does not carry any of the approvals listed then that's one of the most deceptive SDS I've seen.

On some of their other literature the "approvals" are listed under a heading of "Performance Profile."

The oil does not appear on the list of MB approved oils for 228.51.

Yes. Well, technically, no E6 certification can still result in reduced phosphorus, in a 10w-30, 5w-30, or 0w-30 HDEO that is CK-4/SN. My real point in replying was where you said a "proper HDEO...." An E6 is a proper HDEO, and they often have a whack of builder approvals. I'm even using one of those lubes now.

Hi
Thank you all very much for helping me.

Is it actually that important to have specific manufacturer approval rather than just meeting their specification?
Millers are well respected in UK and we have an account with them at work where we use their lubricants and coolants hence they are easy to acquire. Pretty much any Oil is available over here. The American ones are more expensive for obvious reasons.
Is there a good site where I can learn the meaning of all these E6,E7 CK-4/SN designations. They start to make my head spin after a while. Why is Phosphorous valuable etc.
Many thanks.
Tikka

Builder approvals usually cost money to get the certification.

Some boutique oils and oils from small blenders aren't actually certified due to the costs involved. It's not economically practical to get the approval so they use words like "complies" or "meets", however no formal approval actually exists.

The approval is required for warranty coverage if you have an oil related failure. Some oils, which do not have any formal approvals, could actually be superior to the one you are "supposed" to use. This is the heart of the controversy.

Phosphourus is a very effective anti wear additive. It exists in 99.9% of all engine oils in the form of ZDDP (Zinc dialkyldithiophosphates), usually combined with Molybdenum or Antimony for a synergistic effect. Some HDEOs have more P than others. It is proven and has been around for years, except it can poison a catalytic converter before the warranty expires if your engine has an oil consumption problem. As a result, the levels of P are being reduced in all oils over the last 15 years. I prefer > 1000 PPM of P, E6 lubes are limited to < 800 PPM.

CJ-4 and CK-4 are API diesel oil categories: https://www.api.org/products-and-service...el-c-categories

ACEA E7, E9 and E6 are European oil specifications: https://www.lubrizol.com/Lubricant-and-Fuel-Additives/Engine-Oil-Additives/ACEA/Sequences/ACEA-E6-16

Comments from Analyst......Cautionary soot levels. Satisfactory wear metals.


I did note how different the Moly and Boron levels were between the two samples. I suspect they may be different oils regardless of the Jeep dealer saying both times PETRONAS 5W-30 was used.

I would be grateful for any comments on all of the above.
Many thanks.

Can you shed some more light on your driving habits?

Petronas Syntium has several versions in 5w-30 ,under 229.5 and MB 229.51;52 :

https://bevo.mercedes-benz.com/bevo...isten&suchbegriff=petronas%20syntium

The first UOA looks like being with 229.5 Syntium 5w-30, the second-with 229.51/52 .

I would look into the 1.5% soot content -it's on the high side for just 5000 miles. Ever checked or serviced the Fuel Injection system? How is the EGR ?
With this soot % I'd hate to push the OCI any further on a timing chain equipped small displacement engine and address the possible cause first.

Since the engine lacks DPF ex-factory you have a wide range of oil choices - from HDEO's to ACEA C3 MB 229.51/52 .

https://bevo.mercedes-benz.com/d/d/en/Spec_223_2.pdf

Some excellent 228.51 5w-30 oils are available in UK - among them Delvac 1 LE 5w-30; Shell Rimula R6LME 5w-30 ; Castrol (renamed again !) Vecton line of HDEO's etc. (the Delvac 1 LE was factory-fill in MB vans and R6LME is in MAN Euro 6 HD engines).

Millers product above is not on the official MB approval list (it's "meet or exceeds" situation, it may be a good product but I'd stick

to the major companies' products) .

Hi
My driving is mostly short journeys of just a few miles with the occasional long journey.

The oil shows no sign of fuel contamination and engine runs perfectly so I guess the injectors are fine.

Not sure about the EGR. Everything runs fine and I have no exhaust smoke. I always run Shell V Power Diesel too.

I would sincerely hope a Jeep main dealer would use an oil of the correct MB229.51 spec although the invoice just says PETRONAS Syntium 5w-30. Who knows what they do though.

I have had the Jeep serviced since the analysis so that dirty oil is out.

Thanks for the help.

Hi Gents
Anyone any ideas as to why the large differences in the Boron and Moly readings in the two reports above? Seems odd to me. Are 'high' Boron and Moly a good or bad thing?

Thanks,

Tikka

I have an OM642 that is supposed to go 10k oci's. Once I went 9500 on Mobil 15-40M and my test came back showing a 7ppm/1000mi iron level. The tbn was 2. I didn't like that so don't go over 7k oic's. The last uoa I did was at 7500 miles and it dropped to less than 6ppm per 1k. I did tow a motorcycle trailer during that run across the country. I've switched to Valvoline MST 5-40 so I need to test that oil. Started to believe that Mobil 1= high iron business.

I misspoke. The Mobil 1 was 5-40 ESP.
