I know that one of the suppliers to Sainsbury is known as Greenergy. They have a web-site with detailed info on their products.

Cheers Bobby, If anyone else can help too that would be great

I've previously seen conoco tankers in a couple of branded named fuel stations making a delivery.
|
|
I've noticed my local Tesco has now started stocking 97 octane superunleaded. Do any other supermarkets sell it?
|
Funny thing is, round my way, I have only ever seen Tesco tankers in Tesco and Sainsbury tankers in Sainsbury.
I saw a Shell Tractor unit attached and pulling a Tesco Tanker unit on the M6 once.
|
All crude in to UK refineries is the same (there is an established acceptable range for certain attributes). All petrol out the other end is the same (within an accepted range).
The tankers line up, fill up with petrol and then add 'additives' relevant to who's buying the petrol. Therefore the base petrolis all the same there is no concept of Shell say geeting the 'good' stuff.
None of the oil majors owns tankers anymore. They are all sub-contacted out. They may carry an oil companies livery but they don't own or run the tankers. I'm not sure if Tescos own their own tanker or not. Don't think it matters.
All sellers are party to a net fuel agreement whereby they swap fuel if someone has an unexpected shortage. They are one or two fuels outside the agreement such as Optimax but nearly all are in it.
So the only difference between supermarket fuel and branded fuel is the 'additives' unless you happen to be filing up with swapped fuel in which case you could be buying Tescos fuel at a Shell station or vice versa.
The oil majors have never made any claims in their advertising that these 'additives' do anything as if they did they would have to prove it.
Some people including HJ insist that using 'good' fuel increase engine life some people like me say its all nonsense. You pays your money and you takes your choice...

>>I'm not sure if Tescos own their own tanker or not>>
An extremely hard working driver no doubt...:-)
All the deliveries to my local Tesco Extra (the second largest in the UK) are undertaken using Tesco livery tankers.
The drivers don't necessarily know their stuff though. A few months ago the very busy petrol station at the store had to be closed down for quite a while as the driver had put the fuel delivery in the wrong tank...:-)

What\'s for you won\'t pass you by

Can we keep the quality comparison of supermarket fuel to the other thread, I am merely interested in who supplies who.
I appreciate ASDA, Sanisburys, Tesco have their own livery lorries, but who supplies them at the refinery?
e.g. Safeway when it existed was supplied by BP
|
|
Not to Teso Extra at Portwood Roundabout (Stockport) was it? I remember popping for fuel on the way home and cursing when the detour with family (in-laws) was pointless one Sunday not that long ago... and seen it closed since for Petrol/Diesel.
|
>>Not to Teso Extra at Portwood Roundabout (Stockport) was it?>>
But town name wise not all that far out...:-)

Shell have certainly claimed benefits, and they count as an oil major..... HJ is quite right, and there is evidence. However, another thread required for discussion as has been pointed out!
|
|
It depends where in the country they are, different areas have different suppliers, same with the oil giant retail brands, they supply each other.
|
|
I have a cousin who is fairly senior in Tesco management. Its a few years since I've seen him, but about three/four years ago he told me that Esso had the contract to supply Tesco.
|
that Esso had the contract to supply Tesco.
I heard that was true as in re-stocking their forcourt shops, but didn't realise it stretched to petrol as well.
|
Optrex, the retailer I work with is based in Scotland. All our deliveries come from the Grangemouth refinery. Invoices are from a Chemical company, but not a recognised name.
Tankers are usually branded with our company name although have been known to use others eg. Hoyer.
Hope this helps.
|
The small Tesco (Express?) in Leicester used to have a Tesco-branded petrol station but now it's Esso.
I know this doesn't prove that the fuel is the same at Tesco branded sites.
|
|
At one time Tesco were experimenting with small stores attached to automated Esso filling stations. All the ones round here have closed now, probably cos most people I know prefer to pay a person for their fuel.
|
Further to my note above, about two years ago Tesco also opened one of its Express stores at a local Esso petrol station.
The fuel supplied is sitll Esso, but you don't get Tesco ClubCard points even though payment is made at the Express cashouts.
I presume Esso or the original petrol station owners came to an agreement with Tesco to replace their own store with the Express outlet.

Thanks Bobby,
It does seem that the refineries have an agreement to supply each other based on location. This is to reduce the amout of road transportation of the fuel. So who actually supplies who depnds on how close they are to a specific refinery. As an example, apparently all fuel north of the border originates from Grangemouth (which is BP owned) no matter what the forecourt badge says.
Tesco and Esso have a food contract for Tesco Express locations on Esso sites - this does not extend to main Tesco supermarket forecourts.
Thanks for all the help.

In a similar vain to the Tesco-Esso parnership, Sainsburys and Shell have teamed up near me.
|
well for years I never ever used supermarket petrol as I was informed it was low standard grade and a)could cause damage and b) dirty--.
However in the last 2 months I have started to use Sainsburys as my shell petrol was not giving me the usual mpg--what a drastic improvement in mpg with sainsburys is all I can say and I always try to use where possible.
|
|
I Have to agree with the Last post as I have been filling up at my Local Morrisons and always fill the Tank and monitor my MPG, but I used to Fill at Tesco and sometimes still do - at Morrisons I Get around 360 to 400 per full Tank yet at Tesco I get 420 to 450 per full Tank (astra SXI ) on everyday use commuting to work etc. Thats a huge difference and suspect that Morrisons (Mansfield Nott's) are supplying lower quality fuel than Tesco's in the same area. and its 2p per LTR Cheaper at tesco so Have decided to use that from now on and although its 5 mile further away than Morrison's I will still be in Pocket. Note: I have monitored this since buying the car in April 2007.

Fuel is sold by volume so the more additives in it the less actual fuel you get.

I know very little about fuel, except it is very expensive. However, my daughter bought a nice 3 year old Golf 1.6 petrol engined car, from a VW dealer, full service history etc. She has a round trip to work of 50 miles daily. To save money she used the local supermarkets, we have them all quite close. After a couple of months she complained about the car running badly. I drove it and was surprised how flat it was and it just felt 'lumpy'. I took HJ's advice and filled it up with Shell and took it for a 200 mile trip and gave it a good run, through the gears to 4K revs frequently and a steady 80-90 burst every few miles. After that my daughter used Shell all the time and the car returned to normal, responsive running within days. So I speak as I find. Ergo: Shell must be better than supermarket fuel. Best to all. Concrete

"... filled it up with Shell and took it for a 200 mile trip and gave it a good run, through the gears to 4K revs frequently and a steady 80-90 burst every few miles."
You did TWO different things to the car. You put Shell fuel in and also gave it an "Italian tune-up". How do you know which one made it run better? Sorry, Concrete, this proves nothing.
|
|
The criteria are subjective too. It's easy to convince yourself that an engine that was flat and lumpy is now responsive when in reality nothing has changed. If a modern car is being continuously 'lumpy', then it should trigger a fault-which should be addressed. The Golf does use direct injection though-and that is a whole different ballgame from port injection.
|
|
A petrol Golf with direct injection?????
|
|
@jc2
yes, lots of manufacturers use direct injection for petrol engines nowadays. Lots of big claims around for its advantages, that thus far don't exactly correlate with empirical evidence. Has a couple of marked downsides too.

Its all very confusing will we ever get a answer on this petrol diesel debate which is best ?
|
|
Sorry I meant the quality between supermarket fuel and the others.
|

I decided to e-mail Morrisons and tesco so to answer the original post , Morrisons are supplied by conoco at immingham and tesco are supplied by esso, I did not e-mail sainsburys and asda (sorry) but after reading all the posts on this subject and speaking to people i work with and in my own experience I believe that supermarket fuel is inferierior, for whatever reason "I dont know" and it seems that there is also a difference between the different supermarkets, as I posted a couple of days ago "Iget better MPG at tesco's over Morrisons" and reading some other posts IE addition of mineral oil to Derv and not adding important detergents etc to all fuels this then highlights the obvious to me, we Live in a country where we are treated as consumers like SHEEP (one leads and we all Blindly Follow) and I beleive that this extends to all aspects of economics in Britain. Maggie and the torys promoted capitalism and greed in the eightees, what we have now is a direct result of that, RIP OFF BRITAIN, so im afraid we have to accept it. but stay vigilant and remember if a deal seems too good to be true it usually is. sorry bout the rant but Im sure most will agree.
|

I doubt there is a definitive 'best' fuel. The composition changes through Winter/Spring/Summer and this probably has more impact than the variation between manufacturers. Fuel regulations DO change in response to demands from engine manfactureres-Ultra Low sulphur diesel being a prime example. If the manufacturers are happy with EN590 compliance then we should be too.

I know when my grans petrol Merc ran badly the Merc dealer told her to put Shell superunleaded in the tank (NO business connection) - she drives little and then only short journeys.
I have an MX5 and a BMW 120 diesel and use the superfuels when I can - the "super" diesels are supposed to extend the life of the fuel pump- all I knw is that the car sounds more "diesly" and slightly less economical when it gets the standard supermarket stuff, the MX5 seemed to feel more lively when it first got superunleaded (at around 40k miles) that I think is due to the cleaning effect it had when I first started using it - so it gets treated every 3/4 tankfuls
A previous Honda CRV petrol was more economic using superunleaded - only by 2/3mpg - the price differential negated the effect BUT when fuel became more expensive it became worth it to stick to superunleaded
To the "rip off" britain moaners all I'd say is that just because we pay more tax on fuel and booze means that direct taxes are lower in the UK versus mainland Europe (total tax take is pretty similar)
|

You do understand how port injection works, right? Fuel is sprayed against the back of the intake valve, so, unlike direct injection, spray pattern isn't important. Only the quantity of fuel is important-and if that is wrong, the lambda sensor will soon recognise it.
|
|
Mmm. Placebo effect in fuels ... interesting topic for consideration.
|
|
Absolutely huge. That's why the undustry use standardised drive cycles. They are prone to cycle tuning but at least everyone has fiddles to the same tune!
