I know some will say no point in using the v-power in such a small diesel , potentially looking for more mpg rather than mph, better health wise for the engine rather than the fuel save stuff any ideas, has anyone used it for there cr tdi?

or maybe every other fill mix from fuel save to v-power or would this confuse the ecu

Wouldnt bother to be honest. Only petrols are really sensitive to the use of premium fuels, I've never noticed any real difference using premium fuel in a diesel. Just continue to put good quality regular diesel in it and save the pennies.

I have read that normal Shell "Fuel Save" Diesel actually has a higher Cetane No as VPD anyway. I've used it before and the only difference I've found is I'm a bit lighter in my back pocket.

thanx fuel save it is then

for Shell fuel save.

Dont know about the CR but my PD Fabia loves the taste of Shell Fuelsave. I get a quieter car and reliably 1 or 2 mpg more on average. It also regens less.......weird but there you go.

Tried V power for 2 tanks, did less mpg and noticed no benefits. Same goes for BP Ultimate.

One rainy afternoon I trawled the net on fuelsave facts....nothing on tv and had finished my book so forgive me this one. General consensus is that fuel save falls mid point between other forecourt regular diesel and the premium Ultimate/Excellium etc. Has some extra detergents and higher Cetane rating. Gets my vote anyway.

Yes I know its all EN590 spec fuel and refineries sell the same base stock to all sorts of forecourt companies, supermarkets included. What you get with Fuel Save is a slightly better additive pack.

Edited bit.... I find shell fuelsave is the same price as other regular forecourt diesel. SO your paying the same price for imho a slightly better product. That or I am a victim of marketing......I dont work for Shell BTW

I'm convinced

I think it has more to do with marketing than any real gain in performance or mpg. A bit like Slick 50 that people use to add to their engine oil 20-30years ago.

I suppose that the difference in price of a tank of super duper diesel rather than super diesel is only a pound or two so one way or the other it will not break the bank.

I've used V-Power in my Octy VRS CRD 99% of the time since it was new. It's just over a year old, 13,700 miles & has done a lot of town work. It's never had a DPF regen. & I think this would mainly be due to V-Power Diesel. From what I've read, V-Power isn't made from crude but from CNG & thus doesn't produce smoke when it's burnt. I do know that my wife filled up with standard Esso Diesel & the car wasn't happy (maybe the computer was slow to adjust to the lower cetane fuel), once I got it back on V-Power it was back to its turbine like best.

I have to confess though that now it's taking over £75 to fill it's something that might have to give...especialy after all the good comments about Shell FuelSave. :wonder:

According to the shell site it is only additives.

It's strange that they've changed the info...it used to bang on more about GTL (that's what I meant when I said CNG...I'm getting old & confused! )

Here's a slice out Wiki's info on V-Power Diesel:-

V-Power Diesel is a blend of regular petroleum-based diesel and synthetic diesel, created using gas to liquids (GTL), along with some extra additives designed to clean the injection system and improve injection pump and injector lubricity.

One characteristic of V-Power diesel is that it is a lot clearer and odourless than normal diesel, mainly due to the synthetic GTL component.

All I can say is that I chose V-Power diesel after all the problems people were reporting with CRD engines DPF's...& I've never had the regen light on once!

So what your saying is "use the v-power in a cr engine" rather than the fuel-save

So what your saying is "use the v-power in a cr engine" rather than the fuel-save

Yes...if you're not doing the type of driving recommended for a CRD...i.e. lots of shorter, slower journeys. If I were doing mainly m'way or dual carriageway driving then I'd use FuelSave.

It would be interesting to do a poll on the CRD engines with the following options:-

V-Power Diesel short journeys no DPF regen

V-Power Diesel short journeys DPF regen

V-Power Diesel longer journeys no DPF regen

V-Power Diesel longer journeys DPF regen

Standard Diesel short journeys no DPF regen

Standard Diesel short journeys DPF regen

Standard Diesel longer journeys no DPF regen

Standard Diesel longer journeys DPF regen

At the end of the day you can only go with what works for you, but a poll would a least give an indication of a quantifiable effect of V-Power Diesel on the DPF...or not!

So what your saying is "use the v-power in a cr engine" rather than the fuel-save

Your car is designed to run on any forecourt diesel. Its all ULSD that conforms to EN590. Just because its a CR type diesel doesnt mean you have to use special fuel.

If you want to do the best for your car as far as clean engine and minimal emissions then 'maybe' V power will help in that regard.

Diesel is expensive enough as it is. The extra you pay for V power sort of negates the extra mileage you get from owning a diesel.

Personally I will use the fuelsave with an occasional tank of V power or some other brand of premium fuel for an extra clean, be it real or placebo.

This an email replay to a SCM member from Shell

For Fuelsave diesel Cetane is guaranteed 51 typically 55-58

For V-power diesel Cetane is guaranteed 51 typically 53-55;

The benefits of V-power are not derived from the cetane rating.

Hi I am A BIT OF A NEANDERTHAL but what does this mean in real terms?:wonder:

In laymans terms it means if you think V Power works and is worth the money use it or if you think it is a con don't use it. Looking at the posts some approve and some disapprove. I personally wouldn't pay the extra but I might be tempted to use it once or twice a year for the feel good factor.

You could try using Millers, Forte or Red X fuel treatment but that opens up another can of worms that people will not agree on.

Quick chemistry lesson;

V-power is a mix of normal diesel and a proportion of GTL. GTL, or Gas To Liquid is a process developed by the Germans (cicra 1920's) and further developed by the South Africans (however they both used coal as their starting material and this is called CTL). The initial Shell process yeilds a high molecular weight pure hydrocarbon wax which is then treated in a standard refinary process called hydrotreating to produce a hydrocarbon based fuel. the big difference here between GTL and crude oil derived products is that the fuel contains no aromatics, and this is why they burn so much cleaner. Cetane is if you like similar to RON measurements for gasoline, and is a measure of combustability delay. the higher the value for the cetane the sooner it will burn after having hit TDC (top dead centre) in the compression stroke. Therefore a low cetane value will lead to not extracting all of the energy out of the fuel.

With regard to EN590, and for that matter any fuel spec, these only set a minimum level and each batch of fuel will be different. Also since April 2008 it has been a mandatory requirement to include a proportion of bio diesel which i believe today in the UK has to be a min of 3.75% and will be a min of 5% in 2012 (i think, can't quite remember). However, again this is only a minimum as i know EN590 is now at a least 7% max (maybe 10%) permitted. in addition, the overal fuel quality will be dependent on the crude oil source and refinery process. Someone has already said that in reality the base fuel delivered from a depot is all the same, it is just dependent on the additives added at the loading rack to the tanker and this is quite correct, except for the V-Power due to it using a different product.

i shall now take off my anorak and btw, i do not work for Shell or any other oil company for that matter, Jerry
