Branded v. Supermarket petrol / diesel

I have fuelled cars, both petrol and diesel, from all sorts of sources over the years and have never noticed a difference in performance or consumption (and I do review consumption continually) between supermarket and other outlets.

On the other hand I do know that on 1 April when my local filling station was charging 121.9 for unleaded and 123.9 for diesel the Waitrose filling station in Salisbury (9 miles away) was charging 114.9 and 116.9.

+1, I tend to agree, never noticed a difference between supermarket and branded fuel.

See the links that I posted at post number 10.;)

The problem originated from the refinery, not the fault of the supermarket in question. These sorts of incidents can quite easily happen to branded outlets.

I can use google too: http://www.shropshirestar.com/2009/10/12/petrol-pumps-dispense-diesel/

Still has nothing to do with the question of whether supermarket fuel is inferior to branded fuel.

It all depends on whether the supermarket fuel contains the same package of additives that the premium brands have. The EN standard currently does not specify the detergent level to be used. So EN 228 can be met without additives to stop carbon deposits on the injectors, valves and piston crowns. Some supermarkets add detergent packages, but others do not. Shell V Power is only produced at Stanlow, so of the 9 major UK refineries, no-one else produces V power. If they don't shout about cleaning properties, they probably don't bother.

Most cars are produced to operate without problem throughout the world. It's unlikely that a modern car is going to be significantly affected by the fluctuations between fuel in the UK where fuel supplied is, probably, at the higher end of fuel specifications.

At this time, my local Tesco is charging 118.9 for standard unleaded, my village garage is charging 117.9 for the same grade of fuel.

Every little bit helps, Tesco have to recover the cost of their points system I guess.;)

I dont think there is any benefit using the higher priced fuels like super-unleaded, or ultimate from BP, even their own advert I've heard on the radio says you 'could' gain an extra 28 miles per tank, now lets see and average tank at 45 litres would cost about £54 to fill, but at the higher price usually +5p per litre it'll be £56.25, so an extra £2.25 for 28 miles? I don't know if i'd want to pay that, on another thread about actual mpg v officially claimed mpg it is amazing with people describing driving habits made a huge difference.

You would not pay £2.25 to travel 28 miles? What do you drive a GWIZ? :eek:

Might be in for a shock if you work out how much it costs to travel one mile in fuel alone. 28 miles on less than half a gallon is very good.

Whether you could actually get an extra 28 miles is another matter. I filled up with BP ultimate diesel last time, Getting excellent MPG figures averaged 62 on the way home & done 90 miles averaging 58mpg, Best i have managed before was 38mpg.

Down to the fuel, Unlikely. Down to the fact i put the average MPG reading on the trip & stare at it more than the road.
If the mpg drops i take my foot off the accelerator. Dont stop at traffic lights its very bad for your economy. Turning right at the island? Its sometimes better to go right and not around it.

:T PS. please dont crash into me if you decide to do the same.

Tesco always seem to be the same price as the nearest independent near me but with the added factor of a point for every pound they are definitely keeping their prices high as it is always 4-5p cheaper the other side of town in Asda which don't have any incentives.

maybe im wrong but i think all teso petrol stations are supplied by esso feul and sainsburys stores are supplied by BP

You are wrong.

Tesco are supplied by Greenergy (Tesco own 25% of Greenenergy).

Asda and Morrisons are supplied by Harvest Energy.

Sainsbury's used to be supplied by BP, but in 2009 changed to Greenenergy.

In the south-east all the fuel for Greenergy and Harvest Energy comes through Vopak, which is why Tesco, Asda and Morrisons all suffered from the fuel contamination problems in 2007 (http://news.bbc.co.uk/1/hi/6414905.stm).

My own conclusions to this debate are :-

1) There is no difference in the fuel delivered to a supermarket filling station from that delivered to an own garage.

2) There is a big difference in the way the fuel is managed upon or after delivery at many supermarket filling stations. How can the staff that work in the supermarket filling stations (and next week may be stacking shelves) be as proficient as the dedicated manager of a normal filling station. Horses for courses?

3) Apparent savings on Tesco fuel are frequently a myth. Just prior to their 'spend £50 in store and get 5p off per litre' the forecourt price rises by nearly that much for the period.

4) Many own brand filling stations are more competitive. It depends largely on geography and the number of stations in the area.

Just my 2p. YMMV.

I have a MINI cooper and find that if I pay the extra for the ultimate unleaded overall the costs are the same once you have worked out the extra your paying compared to the few extra miles you get per tank of fuel. But the performance is alot better I find so worth getting the ultimate In my other halves ford Ka though the ultimate does exactly the same mileage as the bog standard unleaded....I have been told its to do with the engine, more sporty cars benefit from using higher octane petrol.
