    There was a discussion at work about the best diesel fuel to use.. The vast majority of the people state Shell V Power .. What's your thoughts ?

    Oh no. Can't see this ending well ;)
    I try and use premium fuel where possible, mainly shell.

    What ever is closest at the time but I do tend to avoid Tesco. It's a diesel after all, not an F1 car.

    Shell V Power but any premium diesel will do as Shell is stupidly expensive . Otherwise, the standard stuff with a bottle of Wynns is about the same.

    The only difference between the regular standard fuel and the premium versions is the additives package that is put in at the depot. Fuel all comes from the same depot, it's the additives which differ between the companies (or in the case of supermarket standard fuel, no additives).

    Regular use of something like Wynns is more of less the same as the premium stuff. For petrol it increases the octane rating, reduces carbon deposits in the engine, reduces knock, etc.

    What difference do additives make?

    With regular use, cleaner engine, boosts octane rating, fuel ignites more efficiently so suited for high power/high compression engines with a turbo or super charger. Supposed to reduce exhaust emissions too but no idea if they do. Some people swear by the premium stuff, others see no difference than the standard fuel so YMMV.

    Normal diesel, but only proper fuel station versions.
    I won't use supermarket fuel, seen/heard too many bad things about it.
    Like when our fleet IX35 ground to a halt because of a 'gummed up' fuel filter, the first thing the AA man asked was whether the driver used supermarket diesel (which he did).
    Clearly, whatever additive is used to avoid this 'gumming up' is missing from supermarket fuel to cut costs.

    Never had any issues with supermarket diesel but definitely found the V Power Diesel to seem to run the engine smoother. That was on a 2.2 Laguna. Since I got my Civic, I've exclusively used V Power diesel bar one fill up when I didn't have time to get to Shell. MPG did take a little dip but it was a traffic filled few hundred miles.

    To be fair I've never tried normal Shell diesel. Currently in a car share I can afford to use the V Power stuff.

    I haven't used V-power diesel since my A3 sportback 2.0tdi.
    It made it run funny, lots of 'hunting' on a constant throttle, like the ECU was getting confused.
    That was the early days of V-power diesel though (2005-2008).

    I am acreful about supermarkets as well but Sainsburys use BP only whereas the likes of Tesco either buy on the spot market or their garages can be franchises that do what they want.

    That's interesting.
    So is Sainsbury fuel the same spec as BP forecourt?
    Not having a pop at all, but buying it from BP doesn't necessarily mean they get same spec.
    if it is the same spec, I will consider 'taste the difference' fuel.:)

    I have found Sainsburys to be good on other stuff, never asked about the specifications but of course a given specification can still have wriggle room.

    Don't think you'll go wrong with either of those.

    The V Power adverts make me laugh: "developed in conjunction with Ferrari." Since when did Ferrari know anything about diesel fuel and engines? Surprised the ASA haven't done anything.

    I try and stick to BP Ultimate or Shell V-Power. I was under the impression that these both have a higher cetane rating than regular diesel and also burn more efficiently.

    From what i know is that the crude oil gets refined at the plant and then bio additives are blended with the fuel from anything up to 7 % so who knows what your gonna get from where.

    Octane isn't a term associated with diesel, as it's used to indicate when a fuel will self-ignite.
    IE, the higher the octane the higher temperature before self ignition.
    Self-ignition is not good for a petrol engine, but it is what you want in a diesel, so the octane rating for diesel is actually very low.
    V-power is allegedly made from better base stock and contains additives to make it burn cleaner.

    Which is why I referred to the cetane rating, NOT the octane rating ;)
