Having said the above, irrespective of who pumps the fuel out of the ground or who refines it, the additives determine differences between fuels sold by different chains. This does mean that the design of each fuel being sold is altered by the additives.
There was a set of tests done by the AA some years ago and it showed that Shell V Power produced around 7% better MPG than many other fuels. This is consistent with my own experience of V Power in a petrol and a diesel car. I prefer to use shell in all my cars and mostly V Power. I also add 75ml of Millers Ecomax to each tankful of diesel. This combination delivers a totally different responsiveness from the CDT than using other fuels without the Millers additive. Let's just say that I have never felt the need for any remaps etc.
Here is the thread from 2013 discussing the AA report. https://www.the75andztclub.co.uk/for...d.php?t=163356 |
A useful link MSS. I used to be involved in several oil distribution terminals including two with refineries alongside, albiet over 25 years ago. Intially the first major supermarket to sell petrol and diesel bought fuel on the spot market which was then imported into the UK for their exclusive use, this situation didn't last long, ultimately the supermarkets would draw out of the same stock as some of the major fuel companies. The only difference would be at the point the road tankers were loaded at the terminal if it was for a supermarket no additives were injected into the load whereas for the major oil companies their respective additive would be added. I only purchase petrol or diesel from a petrol company and add Millers to diesel and Redex to petrol, it's down to personal choice and as I don't use supermarket fuel can't make a comparison
As my experience is 25 years ago and a lot may have changed since then and fully understand why anyone doing a high mileage would go for the cheapest fuel available as its so expensive now. Being fortunate enough that I can cycle to work my total annual mileage in all cars is no more than 6000.
One tip I will offer is if I see a tanker delivering to a petrol station I won't fill up there right after as any sediment and water at the bottom of the storage tank is intially stirred up by the discharge and needs time to settle.
