    I have read a lot of for and against "super diesel" ie Shell V power, with claims of better fuel consumption, quieter running etc.. Do any of you have any thoughts on this subject??

    When i had diesel Accord i always used V power but TBH i never noticed better consumption or quieter engine.
    What i did notice that car run smoother then on supermarket diesel,more responsive.
    Might have been placebo effect but that how it seemed to me.
    Apparently V power diesel is cleaner and contains additives that is good for your engine and injectors.

    I have tried Shell V Power Diesel several times and my car is certainly quieter especially when cold and more responsive but I have not really noticed any improvement in fuel consumption when using it. I always fill the tank and keep accurate mileage readings v fuel bought and also find the trip computer in the car is 2 or 3 MPG on the optimistic side.
    In conclusion I have decided a 10p per litre premium over supermarket diesel is just too large especially as I use over £300 of fuel every month. If the differential was say 5p then I would seriously consider using V Power more often. :Smile:

    I've been putting 2 stroke oil in my diesel for a few months now which makes it a lot quieter. I usually put shell diesel fuel save in my car but this last fill up the petrol station only had V power diesel left. I tried that and it does seem a touch quieter than even with the fuel save. Not sure if the cost justifies the perceived benefit though. If I was doing longer journeys I would probably get the benefit from the increase in fuel consumption it offers. But I certainly wouldn't put supermarket fuel in my car, it cheap because it's nasty. The shell V power is definitely a better fuel as its the only one which is a gas to liquid.

    I have been driving a auto diesel for a month and it been on all sort of diesels apart from Vpower ..BUT its still a muffled bag of bolts. No matter what you do the idling noise and the vibration after long journey can be felt via the driver seat.

    Helen say I exaggerate the noise level and the muffled bag of bolts is a myth, hope this reviews helps someone who dislikes diesels like me.

    Full blog on the diesel experience coming soon.

    I have started to use Shell V Power for the past eighteen months or so and I have had an improvement in fuel consumption. In May last year I took my new caravan down to Dorset and only achieved 25 MPG with a tank of Asda diesel. I was quite shocked at this when I topped up at Sainsburys. Prior to driving home I topped up with Shell and there was a noticeable improvement to 30 MPG. Consequently, I now eschew supermarket fuel in favour of Shell.

    I changed my caravan earlier this year to a bigger one, and travelling to Scotland via M6 and M74, and then by side roads, I managed 29 MPG. The route to Dorset was almost all motorway and dual carriageways, so I assume Shell diesel was the better fuel.

    I agree with Robbie, for me the issue is the choice of garage not the choice of fuel.

    I remember once filling up with supermarket brew and listening to the car shuddering at the lights and nearly conking out in a tough part of a strange town...then I topped up with Shell a mile down the road and all was fine.

    Only use Shell or BP usually.

    I agree with Helen but hey I'm biased.:Wink:

    Oh yeah and I know how you hate diesels.

    Thanks for all your replies guys. I filled up today for the second time only, I have only had the CR-V for 2 weeks. I filled up when I bought the car at Morrisons and used cheap diesel. I filled today and used BP ultimate, will let you know if I find any difference.
    I did well over 400 miles on the first tank, and the average fuel consumption was just a shade over 44 MPG. I reckon BP ultimate will have to go some to beat that.

    I had to put half a tank of Morrisons diesel on top of my V Power a while ago to get home from Cardiff and can`t say I`ve noticed any difference. I`ve also filled up in France a few times with their supermarket diesel and again everything seemed fine.
    I`m hoping though that its true it keeps the internals clean so I`ll carry on using V Power
  11. SayamaAccord Top Contributor ★ ★ ★ ★ ☆

    Yep I used the supermarket stuff in France too due to cost, and got away with it

    Well first day out with BP Ultimate, and although traffic was heavy, I have to say the bottom end, low revs, was a lot more responsive than before.
    Maybe there is something to these "super" fuels after all.
    Doing a 200 miles round trip on Sunday, will report my thoughts after that.

    I have tried keeping a detailed log of this in my other car; a Skoda Superb 2.0 TDI. I noted the mileage and the amount to fill up the tank and calculated the consumption. The indicated consumption on the cars computer was always about 1-2mpg higher. I also noted the brand of diesel being used. After keeping this up for the better part of a year I concluded that there is bugger all difference between supermarket fuel and Shell or BP as far as consumption goes. Long term damage due to a proportion of biodiesel in some brands might be a different matter though.

    I've had my CR-V for three years now and it does not like Supermarket diesel about 2-3 MPG less than Shell regular diesel and it runs rough and is more noisy.
    I have yet to try 2 Stroke oil as an additive several people on another forum have used it and say diesels start quieter and run smoother.

    The clip below shows you get 6bhp but no mention of torque increase.

    Thanks for the videos Racy Jace, I am assuming there must be a small increase in torque too.
    I have not used V power yet, there's not a shell garage near me, but I have used BP ultimate and at the moment I am trying Total excellium diesel. With both of these, I do notice bottom end low revs far smoother and quieter.

    The Golf TDi 140 I had before my CR-V definitely went better on Shell V Power or BP Ultimate than on ordinary diesel. When I used ordinary diesel I often noticed a slight hestitation when accelerating, although the dealer said they could find nothing wrong.

    By contrast the CR-V seems a lot less fussy and is running fine on ordinary Shell diesel, so I haven't tried V Power yet. I will probably try a tank full of V power just to see if it makes enough of a difference to be worth the extra cost.

    44 MPG - WOW. I've had my CR-V 2.2 diesel for 3 months and have averaged 35.5 at best. Is this common. I think I agree with IchibanAccord on his view of diesels. I had an Accord Tourer before this CR-V and regularly got 44. I wonder if it's the CR-V that has poor consumption as I assume it is the same engine?

    I have had my 2008 CR-V for five and a half months now, and covered 2646 miles at an average of 42 MPG. The worst I got was 34 MPG and the best was 44 MPG.
    The 34 MPG was a one off, my usual is around the 40 plus mark.
    I do notice that once you climb above the 2000 RPM mark, that knocks back economy.

    If your CR-V is Still new KENQW, I would expect you to see some improvement once things loosen up a bit.

    It's just passed 40k, so not exactly new.
