    A very interesting letter on Page 20 of June MMM written by Ken Dugan who worked in fuel distribution.
    Certainly opened my eyes to the varying quality of diesel sold at Supermarkets and Petrol Stations.
    I also look at www.petrolprices.com for cheap fuel in my area but am now torn between cheap diesel at supermarkets or more expensive but probably much better diesel on the forecourt. Mind its only a few pence dearer but if its better for my engine I think I will change my supplier..:Doh:

    Wouldn't waste my money to read it let alone paying over the odds for my fuel. Asda £113 litre today. I have been using supermarket fuel for many years with a number of vehicles doing 100000 miles of trouble free motoring in each. How could I not be cynical about an article like this?:restmycase:

    we all want cheaper fuel Doug but as you say, the quality can be very different.

    when you think about it, to fill a 70ltr tank will cost £1.40 more at a 2p per ltr higher cost than at the supermarket forecourt...thats only a little more than 1ltr...or around 6 miles in an average motorhome.

    i made the mistake of driving an 18mile round trip to save 3p per ltr (cheaper garage than the supermarkets around here)....the round trip cost me around 5ltrs in my car (15mpg) so no saving there. :Doh:

    the penny didnt drop until i got home :Blush:

    Having not read the article, I'm not going to comment about it directly, but I am going to make a similar point.

    I did over 330,000 miles in my Citroen AX and currently 85,000 in the C3 that replaced it. The former averaged around 70 mpg, the latter is averaging about 60 mpg. Neither has ever suffered issues to do with fuel, and both were filled with supermarket diesel the vast majority of the time (I can't remember the last time I put non-supermarket in the C3, which passed its MOT on Monday....phew).

    It is very difficult to argue the real facts. Use Asda fuel @ £113 and save yourself a fortune.:thumb:

    Which Magazine recently did an exhaustive test on fuel and concluded that there was no disadvantage in buying supermarket fuel.

    Supermarkets buy their fuel from the same refineries as independents and others. I alternate between an Esso independent and Tesco, depending on which direction I'm going that day, and can tell no difference in mpg or performance.

    In the dark ages when I used to go to work ( happily retired thank god ) an engineer in the workshop used to be a diesel pump engineer for the Parkinsons Group and he said that you could always tell a pump used with supermarket diesel because it was all black inside and the seals were always dry he said if you use supermarket diesel then every now and again put a litre of cheap cooking oil in you fuel tank this would help replace the oils removed when the diesel was refined and help lubricate the pump.

    Probably the days when putting a gallon of petrol in with your tank of diesel was thought beneficial:Smile:

    I know mercedes put 0.5 % two stroke oil in the test vehicles when they are running in countries with poor quality diesel
    it is said to improve the consumption a fraction , but I am dubious about that !
    point is , the sulphur used to provide lubrication for the pump etc

    if you want to try this , any grade of 2T will do unless you have a particulate filter , but there is a special grade of 2T for that

    side benefit is reputed to be you get a softer detonation , hence quieter engine

    Hi,

    What I always find questionable when this subject is raised is why if the fuels are different in this very competitive market don't the major players make it clear in their advertising campaigns that their fuel is better because of ???? the additives or other such ingredients that they put in theirs that's not put in others.

    I can only conclude that the lack of advertisement suggests that there is very little if any difference.

    Every new vehicle I have had never been warned off supermarket fuel.

    Wonder why?

    When you're filling a big truck you can see what's going in and I can assure you that there are BIG differences in diesel.

    Pay a bit extra if needs be to get Shell, it's easily the cleanest.

    Having worked in the fuel industry for 33 years before taking early retirement i can tell you that there is a total difference between supermarket and leading brand petrol and deisel, the best to use is B.P. OR SHELL you get far better m.p.g out of both of these .The only way to tell is to brim your tank use it brim again and work the figures out. If you have only run on supermarket fuel you will not notice any difference for a couple of tanks ,the reason is the better quality fuel has to burn all the soot out of your system first before it will work. You will notice that one it runs smoother ,quieter,and feels more responsive,the engine is cleaner .I had in the past because with mine and the wifes cars doing over 500 miles a week each used supermarket fuel when the 5p litre offers was on after 11/2 tanks the cars started to feel less responsive and sluggish and working out the fuel consumptions averaged 5 to 7 mpg less on a toyota yaris diesel and 4 to 5mpg on my 607 diesel,as soon as i switched back within 1/2 tank it was back to normal.
    also the branded fuels B.P AND SHELL THAT IS ALL I CAN SPEAK OF have extra additives to clean the fuel systems and to keep the seals ,rubbers fuel pumps etc lubricated

    So it's coming out of different tanks at the refinery then? Sounds an expensive way of storing fuel. I thought s/markets bought it on the spot market.

    A firm I worked for used Shell for years but succumbed to using Key Fuels instead. Within days the Iveco Stralis's sat up with 'Fuel Filter' warnings on.


    He didn't believe us but had to believe the warning lights on 8 or 9 motors., says it all really.



    p.s. Not a friend of a friend myth, I was there.

    No, the base fuel comes out of the same tank at the refinery but there are different additives added at the point where the tankers are filled. This why people see different tankers filling at the same point and assume it must be the same fuel for everyone. I can assure you if you run a performance engine there is a world of difference between supermarket fuel and say Shell V-Power. VMax

    Of course there's a difference between Shell V-Power and supermarket fuel. It's the same difference that's between Shell V-Power and Shell basic 95 octane! V-Power is a premium and very expensive petrol for high performance cars.

    Where is the hard evidence that supermarket fuel is inferior? I can't believe that some enterprising journalist hasn't researched this subject and exposed these terrible supermarkets for selling an inferior product.

    There is no hard evidence whatsoever that supermarket fuel is inferior or different, it's all anecdotal by someone whose mate is a tanker driver - as if he'd know anyway!

    The only hard evidence that I've seen is by 'Which' magazine, which conducted a fully monitored and exhaustive study of the effects of various brands of fuel and concluded that there is no reason whatsoever why you shouldn't buy your petrol or diesel from the supermarkets.

    I own 3 vehicles, the motor home, a R reg ford escort, and a 1500 Honda goldwing, they all without a doubt run better on the named brand fuel, Fine cant prove a word of it, other than the van smokes badly on start up when supermarket fuel is use and is useless on hills, Shell on the other hand nothing, the escort looses power and sputters on super market fuel, Shell again nothing, the bike is the same and more noticeable of the 3 vehicles.

    This is not a advert for shell, they just happen to have a petrol station half a mile from my house.

    My son runs a 2.0 MR2 turbo, put super market fuel in it and it coughs and sputters, shell or dare I say it tesco super unleaded, and hold on to you hat.

    what does all this prove?

    Simples, you get what you pay for.

    Not scientific in any way, just my personal finding.

    Hi Nick,

    Same here....

    On BP fuel the motorhomes fine.....

    Have to add octane booster to Supermarket fuel for her to pull and run cleanly which somewhat negates the cost saving of using Supermarket fuel....:cry:

    Just my personal finding too.:thumb:
