I'm not really convinced so far, the fifth gear test proved a highly tuned petrol will benefit but there doesn't seem much proof to indicate that a diesel engine will benefit.
It's a pretty common marketing ploy, stick some vague facts and a bit of re-branding on a product and jack up the price. This argument reminds me of the usual body building supplement topic where you have all sorts of people making huge baseless claims about snake oils. Found this posted on a Fiat forum: Quote:

But for me, my right foot tells me whether I want to put it in or not. As I've said before - if I couldnt tell any difference I wouldnt be spending an extra 5p a litre on it. Simple as..... When you've run several tanks on it you probably get used to it. But when you come around to putting normal diesel in - you soon realise the car is a little flat on pick up. TBH I think if you had an out and out race with an identical car with the two fuel's in each - I dont think there would be a lot in it, if anything. But I'm happy with it all the same. Edit: the above is all based on BP Ultimate Diesel, in my own expeience and NOT Shell V Power diesel (as I said in the opening post) I did try the Texaco premium diesel fuel once in my old 330d - but couldnt tell any difference with that either.

I have tried Vpower in the past and noticed hesitation at lower revs but nothing noticeable at the top end.
I may try a few tanks now since I've had my car remapped just to see if the engine behanves any differently. It was only 2p a litre more at the Shell in Oswestry for a while last year so ran it for a couple of months to test the increased mpg/power claims and couldn't really tell the difference. At an 8p premium I think it begins to eat into the fuel savings that the diesel offers. |

Most fuels are from one place. Morrisons buy raw fuel on the spot market as do the other multiples. But its the chemical additive pack the resellers blend it with that makes them all unique.

As a CC driver, I use the cheapest diesel fuel deal I can get.
Performance has been in line with manufacturers figures and economy often better with cheap crap diesel. Last two cars were faultless from new until 90k plus miles. With Petrol the premium is some 8% in cost? But with V-Power petrol I realise that 8% back in economy and make more power so its a win win.

Petrol and diesel are completely different. As is the way they work within the engine.
Higher octane petrol works and has been proven time and again it does. Diesel on the other hand has no proven record of improvement and I don't even hear any company making any claims it does. I'm surprised reading comments about a diesel engine running smoother and getting a couple of extra MPG. On saying that I've always felt that about any of my cars and quite often it's day to day with the same tank of fuel. Guess a lot has to do with the placebo effect but I'm glad you guys are happy paying more for petrol. Pays my wages! |

I don't get videos at work but is that the fifth gear test of premium diesels? I remember seeing that and noting that the car did make more power with fuels like V-Power Diesel and BP Ultimate Diesel.
What I do think though is it's kind of hard to see if the fuel offers more economy just by looking at your OBC. Every time you drive, you'll use a tiny bit more or less fuel than the last time no matter how much you try and drive the same. I wonder if anyone's done a similar test as to that fifth gear one, but for fuel economy. Even on a rolling road it should work. Put 20L in, run it until dry, note the mpg / trip distance when it runs out (obviously going to be way off real life figures). Then do the same but with a premium diesel and see what the mpg / trip is.. About as scientific as I can think of?!

When I put posh diesel in my car I often go to bed with that warm feeling inside me like you have just done a good deed for the day.
Can't say I can notice any difference though.

Wrong guy perhaps? My 2006 model 335i has never been 'in the garage' at all apart from a service. And besides, if it did I would just use my new BMW while it was. |
