    We do a similar mileage with our EV and it only needs an occasional 8 pints of petrol but when we take the motorhome out we get a horrible shock and head for the cheapest fuel we can find. wink

    An occasional 8 pints?🤔 .... I use at least that every time I go to work & back. In the Smart it'll go there & back on a gallon but in the Merc it'll use that each way 😥

    Interesting that the lined website suggests that there 'might' be a slight improvement in a performance vehicle driven hard. Since the majority of us are using engines geared for 'grunt' rather than performance it seems that it would be money down the drain/exhaust pipe.

    I've  read  quite  a  bit  recently  about  the  improvements  in  performance /  PDF cleanliness  gained  from  using  "Premium"  dieselsurprised.  So  I  did  a  simple  bit  of  research  in / around  Crewe  and  found  that  Premium Diesel  is  in  such  high  demand  that  there  is  only  ONE Fuel  station  round  'ere  that  sells  the  stuff  !!  The  other  places  don't  seem  to  be  short  of  customers  tho'  wink

    Petrol no, diesel maybe.

    There is the possibility that diesel with additives and detergents that supposedly come with premium diesel, could help reduce the soot so may be of benefit to diesel vehicles with a DPF and short trips that upset regeneration.

    Thanks all for the info on re-mapping. I'll just have to look into it a bit more before coming to a decision one way or another.

    Still don't see what remapping is to do with the OP. Surely it's just throwing yet another viariable into the equation.

    I have no idea whats right and what's wrong,. But when we bought a peugeot 3008 tdi we were warned not to use supermarket fuel ss those peugeot injectors were susceptable to clogging. We ignored that advice and followed the 'there's no difference' advice. By 60,000 miles we had two injectors fail at a total cost of £1500.  Then until we sold it at 100,000 miles it ran on branded fuel with no more problems.

    I am aware this was an isolated case and not scientific in any way andt it'sprobably pure coincidence and mere superstition but  the replacement car only gets the occasional tank of supermarket fuel

    My vehicle must fit superior injectors to a Peugeot👍🏻. I’ve saved lots of £’s in fuel costs & the cost of a visit to the garage👏🏻👏🏻. Personal choice rules👍🏻

    I had a car with a V8 petrol engine it had done mainly town driving before i got it and had the check engine light come frequently showing catalytic converters below efficiency. When running on supermarket fuel the light would come on after a couple of days on esso fuel it would stay off for months go back to supermarket fuel and light back on in a couple of days.
