Hi,
I'm the owner of a MB E350 CDI Coupe, 2012 model, 265 BHP...
The problem I have is that I'm not sure of what type of diesel I should use...
Regular or premium Diesel ??? Eg: Shell V Power
Please Help !!!

Anyone help ???

Adrian- here in the States, we only have ultra low sulfur diesel. So little help will be coming from this side of the Pond. I've not seen any different grades of diesel here. I for one appreciate diesel performance, we own a Porsche Cayenne Diesel, it's is phenomenal. The cabriolets and coupes on not avail in diesel here.
Is it a huge price different to use the better grade?

Adrian,
Your best info will come from your MB dealer. Also, the owners manual may have info on what fuel to use.
As PJ said, in the US we have only one available type of diesel at the pumps. You get what you get.
MB states that using premium gas is recommended. However, I use the lower octane gas with no issues. This may apply to diesels as well.

In the US, some vendors do dispense diesel fuel with higer cetane ratings. This really only speaks for the lubricity of the fuel, which in turn, will help promote the life of your engine, pumps, injectors, etc...

Thanks Rob- wish I would see a higher grade of diesel for sale in the Northeast.

As I have recently traveled through New England States ...I am finding a variety of Diesel Grades & labeling.
I am being a bit cautious before I fill up in that there is a variety of Grades.
I'm driving 2014 MB GLK250BT...At one large station they had B100,B20, ULSD Cetane 40, & Biodiesel, Super diesel Propol.

I head directly ULSD Pump ,fill up & Leave....I am sticking with ULSD Diesel #2.with the available high Cetane Number...
I find I read much about diesel & refer to what Mercedes Benz is saying, the environmental aspects of Biodiesel seems to be attractive but the supplier being a bit risky....I have a copy of the Mercedes-Benz Brochure on Biodiesel.
I tend not to be researcher when I am on the road.....
I have begun to read that some USA locales possibly have made MB Diesel Owners more observant at fill-up time.

I have a E350cdi Coupe also, which I purchased in Nov 2013, I started using Shell V Power in Jan 2014 which I have used up to the present date.
The little extra cost is IMHO well worth it .

Can you be more specific? What are the benefits? Performance, economy, etc?

According to the information the Cetane Level in the UK is as high as 51.
In the USA, the cetane levels are generally below 51.
I have seen term Super Diesel but I use branded ULSD with the highest Cetane level.
In general terms , a Cetane level of 51 is excellent .
You should consult your manual concerning Cetane Level.
The tuning & specification of the MB E350 CDI could be different.
Cetane level of 51 would be a premium diesel .Petro-diesel derived
Please consult term Cetane in your owner's manual & proceed .
The UK and EU Countries & Australia are following a direction toward ULSD Diesel.
In the USA, there is now a variety of diesels , there are few that are not recommended for Mercedes-Benz Vehicles.
In the USA , Only diesel with ULSD label is approved (up to 5% biodiesel )
Though there is a direction towards Environmental Issues . Biodiesel derived from various sources are restricted.
B20 biodiesel is restricted for Mercedes-Benz Vehicles
Term B100 Biodiesel is not approved for Mercedes-Benz Vehicles
The use of Blends in the UK is an unknown.
In UK & EU Countries , there are a greater numbers of diesel vehicles.

After further research : UK derived SHELL V Power Diesel
CETANE 51
Please consult Mercedes-Benz Manual or Mercedes-Benz concerning MB E350 CDI Coupe for advice.

Term Nitro ,synthetic additives

51...thats nice.

HONDO250

In the UK ,EU ,Australia & other countries there are different labels for diesel fuels. It is unknown whether there is more of a move to use a Biodiesel fuel .
In the USA :I see SHELL V POWER but that is a High Test Premium Gasoline.
The response to a person owning a Mercedes Benz in another country frequently different number Label for their MB Model.
A MB Owner in the USA would quickly have Sticker shock on any cost of Petrol/Diesel Fuels. In Europe & many other countries there are more models of diesel Vehicles....

As I have traveled mostly in the EAST COAST of the USA, I have already said in previous posts that the New England States have choices of Diesel Fuels, Biodiesel blends...most are not recommended for newer Mercedes-Benz vehicles or restricted approval when use is unavoidable...
and Mercedes-Benz has a directive on bio-diesel fuel B100,B20 , the maximum percentage of biodiesel at 5%.
In the mid-West & California there possibly be more Mercedes-Benz Owners asking about blends available * & usage in All Mercedes -Benz Vehicles.
Magazines like Truck Trend have articles on B20,B100 & Branded Propel Biodiesel B20 using the Ford 6.7 Power Stroke as an intended market.
B20 biodiesel is on my Mercedes-Benz List RESTRICTED & when USE /Unavoidable.
The Article speak of California & future market share in the US STATES...for PROPEL (not a SHELL PRODUCT).

There are Environmental Concerns STATE TO STATE , Soya bean , Grain derived & Rending Plants of Animal fat also are in the mix...as is Reused Fry oil, diesel oil smelling like fried chicken & french fries.
Such plants do exist & are said to produce quality controlled. biodiesel.
Not planning to use biodiesel at this time for my MB GLK250BT

Rob CL

The reason for any bio-ready vehicle's "B" rating is due to the fuel delivery system as a primary, then catalyst/emissions hardware as a close second.

Ergo, if one were so inclined, they could upgrade the fuel lines and pumps in their system (as well as replace/modify catalyst systems where required) and run B-100.

Overall, I wouldn't go anywhere near diesel with a rating higher than B-5.

All are good points concerning Diesel fuels .
There seem to be trade-offs & as far as biodiesel ,I just follow what Mercedes-Benz published concerning the matter.
Further ,I relate specifically to the MB GLK250BT I drive.
Since ,the Ultra Low Sulfur fuel is not usually above cetane 40 ,that what I use.
UK & other european nations have diesel fuel with cetane 51
The introduction of Biodiesel formulas ,also has a excise tax.
The tax system is different than than USA, & Canada is not the USA.


Mercedes -Benz is using their term restrictive use ,just in case .of B20
My diesel is not a Ford power stroke diesel
I am not planning to convert anything in my Mercedes to burn Biodiesel B100 but others may encounter problems in certain States like California .
I anticipate more will be written about does & don't from Mercedes.
There are owners of old Mercedes -Benz who burn blends of Home brew Biodiesel made from fry oil & the exhaust smells like french fries ,it is choice that is possible ,the chemistry is from a biodiesel cookbook .
I just passed a Cummins -Dodge Power wagon today , two stacks blowing black oily smoke ,a protest, i suppose. Rolling Thunder ,probably illegal , I stay clear .
