Does Supermarket Fuel Produce Lower MPG?
Discussion
Fuel must be in specification when it reaches the furthest point in the supply chain. When i worked for an oil company our 95 ron was closer to 98 at the refinary gate as it degraded with time and distance(pipeline) to allow it to be still in spec when it arrived at the furthest terminal. So brand x may be excellent in the north and poor in the south. This does not account for large volumes traded between companies allowing access to terminals in regions where companies have no infrastructure. If several terminals are available for collection it can be a lottery where the fuel came from.

None of diesells are better than fresh regular!!! One day been lucky in Sunderland I filled in regular diesel and Fuel consumption been lower unbelievable!!! I wanted put in better but I didn't!!! This mean delivery driver put ultimate diesel instead of regular!! So I am hundret percent sure that they put them regular instead of goodquality!!!
Delivery driver is happy with 100£ in pocket for filling regular only you can ask for example checks
Ha ha ha ha ha , probably in the house drinking the diesels himself...........Delivery driver is happy with 100£ in pocket for filling regular only you can ask for example checks
This thread is like an unscalable wall of ignorance and half truth.
Quite amazing really.
I initally started typing to get some sense Into the discussion.
I gave up.
Find some peer reviewed papers on this. Quit the hearsay, stuff my dog told me etc.
And to answer the original question. Try it and see. Only way to find out due to the huge number of variables involved.

It seems to me that some brands of car are more sensitive to different fuels than others,and some are completely un affected.
That would lead me to believe that it`s more down to how lazy the manufacturer was in programming the ecu software to allow differing fuel types to be adapted for.
Otherwise how would you explain that one type of car runs fine on anything but others are picky?
If one car can deal with it but another can not,then surely that is the cars fault.
In spite of all the differing methods employed to achieve combustion,it all boils down to squirting it in and igniting it.
If its pure luck as to what you get from where then in 20 odd years of driving I have been lucky 100%,I dont believe luck has anything to do with it.

Here you go,here I am!!!
Is your gas Suplier British gas??eon??scotish power??or which one "fufumoneysucker1"??they cannot provide you different gas from same pipe!!!!Fuel cannot be worst than diesel 1950,1980,1999,2005,2012 but seller can change it by additing vegetable oil or petrol or advertisement or buy cheaper in summer sold in winter without winter antifreeze additives

I get the best MPG out of Tesco Momentum.
The 5% additional cost returns me a 25% improvement in MPG.
Even if your car is set to run on 97+ I doubt you can actually get a 25% improvement from super. So you go from say 40 to 50mpg from reg to super unleaded? I just don't believe that's possible. The 5% additional cost returns me a 25% improvement in MPG.

Worth noting the 528 does run smoother on Shells unleaded and seems to pick up quicker at lower speeds. That, and the MPG gains and the fact it's only ever a penny more than the supermarket down the road makes it worthwhile. I fill up there whenever I can.
I ran a BMW 530i and tried a number of different fuels in it including a sustained period of using V Power. Every time I filled up I calculated MPG and noted the result on a spreadsheet. There was no consistent mpg difference between any of them including the so called super fuels.Edited by sparks_E39 on Sunday 29th January 09:35

The problem is that many people don't understand why personal experiences and anecdotal evidence are not good sources of data.Quite amazing really.

I tried to get a grip on it with my own car some time back and gave up. I simply couldn't collect enough data points to produce anything meaninful, especially when I considered the other vairiables such as variations in type of driving, changes in seasons, variations in tyre pressures etc etc.
As I said I didn't believe own words so yesterday when I nearly didn't reach Newcastle upon tyne Shell garage with 3 l in the tank I filled in V-power 144p/l and I think it's comming down faster!! But I will try one more time if I reach Newcastle or Sunderland on this rubish vectra.as I said diesel must be fresh and not many people fill in this expensive! Additives must be ad to Fuel tank to get properly mixing while you driving. rest of additives are still on bottom of Shell garage tank! Thats why they call them additives to mix up
As I said must be different Engine Vauxhall vectra as I cannot get better mpg on Ultimate or Vpower!but regular diesel from asda is saving money straightaway.I will try it probably next summer again but there been reasons as I wanted additives for freeze weather.but this are not added in UK for health but go to Germany in winter with UKFuel and you will see difference after fill in.Vpower and ultimate need probably warmer weather or different Engine where is different materials on valves, pistons,injectors,and probably it's for older Engines to help them running faster as them they will stop making regular to help people save money

I average 16mpg with regular and 20mpg with Super, even now that I'm sure, I still alternate what I put in each time, just to triple check my already conclusive results.
