Does Supermarket Fuel Produce Lower MPG?

Hmm that's very odd, 5mpg is a massive difference.
It was in the summer that I tested the Vpower stuff, and it averaged 35/6 IIRC, compared to 40/41 for the regular stuff.Obviously I'm not trying to say Vpower is crap, I'm just stating what I have observed in my car.
It might be worth nothing that the combined official figure is 39mpg I believe for the Puma, so it's not like it drastically over or under performing.
Hi,
I have been running my bikes and Cars mainly on Sainsburys own fuel, but have not been too impressed with the way my bikes (x2) and cars have run. My diesel Golf doesnt like Sainburys City Diesel..always lots of unburnt diesel comes out shortly after start up (yes it is regularly serviced). I will try BP fuel next time to see if there is a difference...
The other day I need to fill up my CB250 at a BP garage. To my surprise the bike is running much better than it did using Sainsburys fuel
I was sceptical about the claims made by Shell & BP and a London Black Cab driver friend, etc prior to this, but the fuel quality is really noticeable. The bike runs much smoother & I can turn the choke of much earlier. Its a pity that BP, Shell Esso, etc charge much more than the supermarkets!!
I hope this helps

I think its a bit quicker than that. When we used to go on holiday for 2 weeks and dad had filled the car to go ot the airport he said he noticed a difference in performance between going down and coming back. The smaller and therefore more volatile alkanes will have evaporated off in two weeks. Depending on ambient temp of course.
They ain't half some bulls
t being shoveled around this evening.No. There are going to be many factors that have a geater infuence on MPG than a fuel produced to a EU standard. Neither will supermarket fuel clog up the engine etc. Infact the ethanol content in tesco fuel helps to clean fuel injectors etc. For non performance cars 95 from any major uk supplier would do me. Performance cars run better on 98 because otherwise they have to run less than optimal timing to prevent knock.
Im pretty sure at uni they have tested the premium fuels and tesco 99 came out the best, but there wouldnt be much in it. If you want to lower mpg drive more economically rather than trying to compare fuels.

My car isnt exactly high performance but it likes 97+Im pretty sure at uni they have tested the premium fuels and tesco 99 came out the best, but there wouldnt be much in it. If you want to lower mpg drive more economically rather than trying to compare fuels.
The supermarkets supply over 40 percent of the fuel sold in the UK. Shell nor BP refine fuel in this country anymore and cold flow properties are refined in as opposed to "additivated (if there is such a word !) later. Given the debate on this subject the general public would be surprised to see the supermarket fuel tankers being loaded at the same gantries as the oil co. CM ps oh - and you can't knowingly buy diesel in this country from any retailer without it containing up to 7 percent bio 
Always use Shell. Not for any particular reason though.
There's a Sainsbury's petrol station on the opposite side of the road, literally about 20-30 metres away, and they always tend to price match each other.
It usually depends which direction I'm heading (to or from work) as to which I use
both seem to get roughly the same MPG - if there is any difference, it certainly isn't noticeable.

All depending on owner petrolstation/ leaseholder and if they have keys from tanks.asda fuel cannot be poor by 5pence or 3 pence a liter!!! Private esso somewhere in middle town of small citie have vegetable oil in diesel if owner have shop or takeaways while in big city it's different!!! I had no problem with smoke on particular filter with any asda diesel!!! But one day I decided put in BP Ultimate best only 3.50£ more on full tank!!!! Brand new Spennymoor garage!!I decided always fill in and check fuel consumption!!! Never ever again!! It's trap for millionaires to spent more on repairs. My car started fuming and consumption go higher!! Mainly if not many people buing this diesel and is 2 months older than regular
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
