Premium Diesel

No I don't buy it, partially because I nearly always fill up locally at a Super market, but I do put a slug of Millers Eco Max additive; works our at about £2 per tankful, and you can tell the difference (well I certainly could on my t5 174, but haven't actually tried a back to back with my t6 204), it went faster
, but I never really measured economy.
It is also supposed to be kind to the engine it terms of longevity but who knows?
We only do around 10k miles/year = about 40 tanks full= about £80 in Millers. We plan to keep this van for may be 12 years (*like the last one), so if it helps the longevity all well and good.
Whether or not Millers turns Supermarket fuel in to Shell/BP turbo nutter fuel is any body guess????
I do remember a TV motoring magazine testing petrol fuels, and they thought it only made a difference to highly tuned engines such as Scoobys/Evo's etc.

whoops maths error 10k miles/yr = 20 tanks/year = £40 in Millers (even better value) so much for added economy
I use the millers addative in the car and van . It helps the engine pull at lower revs but we notice it most when we pull the caravan with the 4x4 . If your doing motorway driving you won't notice any difference and don't get it on you as it stinks . If I use supermarket fuel for towing with out the millers it feels like the brakes are binding. People say all fuel is the same but put one and a half ton of caravan on the back you can see it's not true. Some people put two stroke oil in but not all the oil is dpf friendly so I would stay with millers.
I have always used premium fuel in my vehicles as i remember working for a chap who worked in the fuel industry advising the big companies, he told me about the supermarket fuels and the bp/shell etc fuels . he said the supermarket fuel were very pour quality and does not do engines any good in the long term. He went into a lot more details but at was the bottom line.
interesting to read some of the facts and theories on this subject

I can only give my opinion anecdotally on this. I have been driving diesels for the past 13 years, a number of makes and models, averaging 30k miles p/a in that time. I have used a variety of fuel suppliers from supermarkets to branded supplier forecourts. I can honestly say I have had zero issues with fuel quality, zero emissions issues and I have never noticed any problems with fuel quality.
I do not believe there is such a thing as poor quality diesel sold in this country. More likely there could possibly be rare issues where the fuel has become contaminated by water or foreign object particles like rust etc, but this would be down to the forecourt rather than the fuel 'manufacturer'.
It is interesting to note, that the diesel engine was originally designed to run on a variety of oils, from kerosene to vegetable oil, although I realise they have come a long way from then.
I think the difference between supermarket v BP/Shell Ultimate etc etc are additives of various descriptions (detergents/lubricants/cetane improvers) and underlaying there isn't an actual difference in quality i.e. they come out the same refineries, it just what you add to that later that makes the difference, be that yourself or what shell/bp put in.
I notice that Millers say you can double dose which adds +8 to the cetane, which would make a big difference to the engine running on many vehicles
What you are saying is true old Diesel engines could run on chip oil but the new euro 5 or now 6 needs a very clean burn or it makes soot and this will build up on all the parts on the emission controls and fill the dpf faster. All these things reduce power , mpg and reliability of the engine that's why vw found a way around it . If you only use your car for the school run I would only use the best fuel or addative. This my first vw but my Vauxhall and transit are a pain as they go into dpf regen just when you don't want it . So far I haven't noticed a regen on the t6 if it stay like this I would replace the car with a vw diesel .
I agree @Chriswhit the fuel is refined to British Standard, it's what is added after that makes the difference. I usually use supermarket fuel but after looking on the web and the claims on performance and mpg I'm going to try both brand standard and premium diesels and see if there is a difference.
Performance hard to tell really but mpg should be easy enough.
Might take a while as I don't do big miles, anyone on here doing regular high mileage trips who would volunteer to trial this?
To be fair, all of my cars get changed at 3 years old and around the 90k miles mark. Most of my mileage is also motorway driving, so probably ideal conditions for the engine and dpf etc.
I'll happily accept that the additives in the premium fuels may go some way to prolonging the life of the engine and ancillary components.

I'm also quite excited that I managed 41mpg on a run down the A1 at a steady 70 yesterday, best figures so far!
I didn't use cruise as it stops the coasting function and costs me 2-3 mpg on average.

I will be really impressed if I can get close to that. How many miles have you got on you t6?
I guess 4motion/dsg/204/all whether tyres will hold me back. Oh and a heavy right foot

5k now @Chriswhit that was four up luggage and three dogs too!I will be really impressed if I can get close to that

Average so far sits at 36 mpg, not many motorway miles, mostly local and A & B roads.
That is on a 4motion/dsg/204 Caravelle with the extra weight of trim and seats etc, so there is hope!
