What Diesel?

[markjay]

Well I use supermarket diesel,I do put some synthetic two stroke oil in every two fill ups,but in the interest of me finding out if the car will do more mileage on good stuff,is BP stuff ok or do I have to find a shell garage.

Both BP Ultimate and Shell V-Power will do the trick.

I go to BP and put in their normal diesel. If I need to fill away from home I'll go to anywhere except a supermarket. Car runs fine and I'm happy with that.

Vpower is noticeably better than 95 Ron in the C63

I recently tried Shell Nitro in both our cars, it was 16p a litre more expensive but I didn't notice any difference at all. Im not saying there isn't a difference but not noticeable to me.

Thanks for all your replies guys will be heading to shell by the looks of it Will update on mpg etc

 

[John Jones Jr]

Sorry, couldn't resist.

I switched completely to shell V power before Christmas (same time I got a shell card!)

Noticed much better mpg, only thing that could be placebo is that the engine seems smoother but I can't prove that

Shell V Power for my E350 cdi , looking for AMG BADGE to stick on the boot
Should this have been posted in the AMG lounge

Shell V power

On my last car a Saab 95 1.9 TiD I had loads of DPF issues and a bad tickover, very lumpy. new turbo, DPF and EGR was probably what sorted out all the DPF issues but it still ticked over real lumpy. That and the suggestion that the Shell V power burned a little cleaner prompted me to swap to that.

Car ran much better on V power, tickover greatly improved.

I also seem to remember seeing that it contained more/better cleaning additives then the regular stuff so I stuck to it for the life of the car.

Picked up a 2009 E320 last week, swapping that to Shell V power too.

Just my 2p...

"Shell V-Power Nitro+ Diesel is formulated with a powerful cleaning agent designed to prevent and remove performance robbing engine deposits that can be left behind by non-premium fuels. Our advanced formulation is designed to work under the extreme conditions of the fuel injection system, breaking down and cleaning-away harmful gunky deposits."

What Shell say in the marketing blurb, make of it what you will...

They are not saying anything different to what Millers, Forte, Redex, etc, are saying.... which in essence is exactly what this is - fuel additives pack that includes detergents.

This is not a food product so they are are not obliged to say on the package what exactly goes into their product, though you could work it out if you downloaded the relevant Safety Data Sheet.

I use shell vpower diesel in my girl !
Last one 100k on the clock no issues with injectors ,dpf anything,not sure about the fuel economy because I never bothered with it!lol

I've never bought a litre of diesel in my life so I have no opinions on diesel fuel quality ....except to say that if the British and European standard EN 590 which legally defines the quality of diesel fuel was written properly and the car manufacturers designed their engines to run properly on the standard fuel there would be no need for this debate. If the expensive fuels have some magic elixir and it improves the way the engine runs it should be defined in the standard and then it wouldn't matter what or where the fuel was sourced.

Same goes for petrol.

I wondered about that. I have a E350, and Honest John always bangs on about Shell V-Power Nitro. It costs about 5% more than regular diesel, but he always said it gives 10% more MPG, and is much better to the engine.

So I tested his theory. I did 2000 miles on supermarket stuff, and 2000 miles on Shell V-Power Nitro. Sad I know, but he was right, so now I stick with Shell, as it's apparently better for the engine and is actually cheaper at the end of the day!

Filled up VPOWER today. Let’s give this a go

True, but then you can have a standard that sets the baseline, and then have some products that exceed it.
A bit like tyres... any tyre that meets the EU standard is good enough to go on a road-going car, but some drivers prefer to use tyres that exceed this minimum spec.
The risk in writing a standard that meets the upper end of the scale is that it is robbing consumers of choice.
E.g taxi drivers who run airport shuttles would most likely prefer low-cost hard-wearing tyres that meet the minimum safety and performance spec, while many C63 drivers will want expensive tyres that allow them to safely make of the most of the car's capabilities regardless of cost.
Not everyone keep their cars for 200,000 miles, and understandability many motorists don't really care what happens to the engine once they passed the car on, they just want to spend as little as possible while the car is in their ownership.
So I think that setting a minimum standard and then allowing consumers to choose from a variety of products ranging from this base standard and upwards is actually a good thing.

That's a fair point but the base standard is just that, a standard with a scientific basis while the improved versions might be better or they might just be marketing. So I'll revise my point and say there should be a defined standard for the basic product and a defined standard for the improved product.

 

[TheFoX]

I think of EN590, and any other standard, as a minimum requirement, otherwise manufacturers could foist anything on us.

Standard supermarket diesel meets this standard, whereas branded fuel tends to exceed the standard to some extent, depending on the product, so Shell FuelSaver is designed to burn less fuel per mile, whereas Shell Nitro+ is designed to increase the cetane number and add extra protection to the engine.

It's like tyre choice. Do we buy Continental, Michelin, Dunlop, Kumho, Toyo, or some unknown cheap name. All will meet the standards set for road going vehicle but each will have its pros and cons.

As for me, there aren't any Shell stations near me, so it is Gulf or Pace.

No BP Ultimate in your area?

 

[grimree]

I asked the tech at my local MB dealer, he said you're wasting your money, use standard diesel, it's what the cars designed for

by the way - I've found that I get better mileage using standard diesel over premium?

 

[Thrash]

When I had my M140i I would only use Shell V-Power/Tesco Momentum (which BMW recommend), then I was out one day and needed to fill up, the nearest station only had regular unleaded which I used. No difference whatsoever, from then on I started using regular and I couldn't tell the difference at all - not in MPG or performance.
Maybe on a track the difference would've been noticeable but for running about town and up and down the motorway - no difference at all. I've never used any sort of premium diesel, ever.
