VPower diesel burns cleaner so you have less soot - better for DPF cars as you regen less often.
Better for emissions but doesn't make a huge difference on mpg. Lower cetane in VPD compared to FuelSave so it burns slightly more readily, hence the lower soot. Also smoother idling etc (IMO)

Is it Shell or BP thats started adding GTL(gas to liquid) to the fuel giving a cleaner burn?Unlike diesel it is completly clear and when burnt gives off a lot less soot, which is very good news for EGR's, DPF's etc.
Going back to the comment of diesel is basically diesel. No it isn't. Fuel is basically a store of energy. The higher the quality of fuel, cetane level etc, when the fuel gets compressed and goes bang, it goes with a bigger bang, giving more power.

Not on the likes of a tdi centain levels don't make any diffrance at all diesal is an oil not a fuel as such the tdi engine system works by compression not burn its the compression which makes it fire having a higher centain level don't make it burn with a lower compression so there for can and will make zero diffrance to the fireing rate at all.
it still goes bang with the compression how do you think it expands?? Regardless of wether or not its oil, it still has a stored energy level and the cetane level is indicative of an increased energy level. Not sure if GTL has more bang.
What am saying is it don't burn as a such yes it has stored engergy but the tdi engine will only allow it go so far with each cycle of the engine unlike a petrol where it will advance its timing each cycle there for the higher ( stored ) energy will make the car go faster the tdi engine don't do that.
I work closely with feathers which is a diesel speicalist company and thy have samples of diesel stateing back since 1988 and each sample has changed so much u can even tell just by the color that diesel in the last 5 years is weaker.
More of the reason injectors fail from fuel is the lack of lubrictaion used in the fuel these days so the injectors end up sezieing up and leak through causing lack of compression.
I have tested verious fuels for about a year and I can say some smoke less than others but none of them make any performance diffrance or any thing else.
I also even tryed adatives even tested using 2 stroke minarel oil as an adative and so far out of all my tests that's the only thing thy made any diffrance but it only made the engine quieter. But creates higher sut levels. This fuel convo pops up so much.
All tests carried out by verious people have come back with the same results as mine which was what ever fuel u put into ur Diesel engine will do the same job as any other

Any experience with GTL then?read something about 3years ago saying it was going to change the dirty diesel burning world, not having to rely on crude etc
Not really used it heard of truck company's using it but only as an adative not a full fuel. From what I know about it it's basically the same as using diesal just it's not very comman and it does smoke a lot in the trucks I know of that use it so it will have a high sut level
VPower diesel is a blend of GTL and normal diesel (hence the lower soot production) along with cleaning additives.
I emailed Shell 2 years ago regarding cetane levels in both Vpower and FuelSave and this was the response:

It's not cleaning the fuel is lacking its the lubrication it's missing cleaning adatives don't and won't make any diffrance to the engine yes possibley over 200000 miles it might help but I still beg to differ.
I work for Volvo trucks and Volvo are always testing systems to get lower emissions to meet legislations from governments and to gett better mpg.
Trucks do an advrage of 120000 miles a year running on bunker fuel which in people's turns is one of the cheapest u can buy so there for highly likely the lowest spec in ur turms
These engines have very small fuel problems so if the fuel was really that bad then am sure they would say change it. The biggest problem try have is injector failur due to lack of lubricaton as I have Said before.
It's not a cleaner tdi require to make it burn or perform better its lubrication in a tdi
Which fuel u use will all do the same thing in the long and short term of use so why pay more money for something that ain't got any faults with it

Shell state that Vpower diesel has added lubricant as a result of reducing the amount of sulphur in the fuel along with the detergent package, so it does have the lubrication needed to keep injector pumps happy.
For the extra u pay the diffrance anoint worth what they so called state is better that's what am trying to say the sight so called inprovments they have made don't make a diffrance to make it worth buying my car ran no better on vpower just put a bigger hole in my pocket
Just out of interest, do big trucks have DPFs as well? I was wondering whether they suffer from the same rise in sump levels as cars do when doing a regeneration (thanks to the bio-element fuel suppliers are forced to include).
Although I did see that DPFs were thought to be planned for implementation in large vehicles 2012-2013 to meet Euro VI emissions regs.
Yes some trucks do have PDF filters but there more of an after market fitment ie to make a euro 4 to a euro 5 we fit them so trucks can enter London and to behonest we ain't had any probs with them and have been fittin them for about 4 years now.
Bio diesel does cause pickup pipes to get blocked due to the fingiee that grows in it but thats why there filters put in place

Do they they must be the bigger sized engines and god help who ever owns one of them add blue is so unreliable it's in real and what makes it worst is add blue is so highly corrosive to copper and brass the second one drop touches a copper wire it will corroded the full wire with in mins so there for if one drop touches ur main car loombe say by bye to that loombe replacement is the only way once it touches copper wire
So add blue in an engine bay is Suicide

It's because the DPF has to be placed down the exhaust as opposed to near the engine. They use the adblue to promote higher EGTs
I only use shell after issues with ASDA fuel on two occasions.
I have regularly kept and eye on 2 cars that were continually ran on tax free red diesel, saw them almost every day and they ran better on a mixture of that and millers than on any "super fuel".
I was very surprised at it TBH.

Used Morrisons probably all my driving life as the garage isn't far from me.
Done about 20k in the Leon since I bought it and ran it mainly on Morrisons, however started to use Shell and sainsburys of late and DPF hasn't regenerated as often so that biodiesel fact could be true. I don't see any difference in tank mileage or MPG.
