supermarket petrol

Grangemouth fuel

All fuel is definitely not the same. The base is the same but the additives packs are different. Up here all the base fuel comes from Grangemouth refinery no matter the brand but the additives are added later. Every time I use supermarket fuel in the car I get a good 80 to 100 miles less to the tank and the performance isn't as sharp. I avoid it on the bike like the plague.

Realising that all fuel used anywhere in Scotland is coming out of Grangemouth refinery, I find it hard to believe that each tanker load, dependant on which supplier it is going to, is altered to suit them. Who would be responsible for this? , the tanker driver? the bloke loading the tanker?
I tend to think it all comes out the same big storage tank on site, unless anyone knows different.

Well, my brother is a Shell tanker driver operating out of Stanlow, and I will pin him down to confirm it, but he said iirc that he is responsible for supervising the additives. So it all comes out of the same big tank, but what get's put into the forecourt tanks is different based on hat badge is on the front.

I've heard that from drivers as well, they are responsible for putting in the additive package.

so the additives give the petrol a higher calorific value then?

hmmmmm

 

[Grey Beard]

I would suspect that the additives boost the Octane Rating of the fuel (rather than the Calorific Value). Modern fuel injected engines will automatically adjust the ignition timing, so as just to avoid pinking, hence maximising performance.

Not done enough driving/fuel consumption tests in Germany. However, I used to check this rigorously in Ireland on runs averaging 25miles or so and always used Shell petrol. There was one garage that was very definitely suspect and always returned a significantly lower mpg performance. Don't know if this was due to an inaccurate fuel pump gauge (but they are verified by trading standards) or just inferior fuel (for the same advertised grade).

Local BMW motorbike stealer in Germany didn't rate the E10 bio petrol and suggested that was lower in Octane/RON Rating, though it is supposedly 95 octane.

I have been running a Diesel van for the last year. On the same regular journey (40 miles, nearly all clear country "A" roads) I get 34-36mpg on Shell diesel. On Morrisons, I get 29-32mpg. I haven't noticed any performance differences, but I didn't buy it for performance.

I know nothing but CW posted this in their forum recently.

Once again we have a customer's bike (R1100RT) in the workshop to have new
valves, and once again the customer has always run the bike on supermarket
fuel. Let me say that I am sure that supermarket fuel is wonderful, but
every time we get a bike in with burnt-out valves the common denominator is
the use of supermarket fuel. Bearing in mind that most motorcyclists I talk
to use branded petrol I'll let you draw your own conclusions. I usually put
this message up once a year because that's approximately how often this
happens. It's uncommon, but when it happens it's expensive.

When I got a Discovery 3 I systematically tried all the main diesel fuels in our area and logged everything for 10,000 miles. Yes it's diesel and a 4x4 but these are the mpg results:

V Power 24.95
Shell City 24.27
Tesco 23.39
Esso 23.08
Waitrose 23.84

The difference is marginal but yes it does run slightly smoother and with no smoke on fuel throttle with V-Power fuel. I just buy the cheapest fuel these days for both cars and bikes.

so the additives give the petrol a higher calorific value then?

hmmmmm

It doesn't have to be higher calorific value - more efficient combustion will get more of the calories out of the petrol.

Shell V-Power is definitely better in my 2010GS than 95 octane from anywhere elese - I try to avoid Tesco petrol if I can.

 

[Engineer]

Odd that when bods are in the UK they dismiss supermarket fuels, but when they are abroad they are more than happy to dive into every Super-U, Le Clerk and shonky Speedi supermarket they can find... normally because it's cheaper.

Someone will be telling us next that Continental supermarket fuel is of a superior quality to English.

Convenience is the main factor it when abroad - but 90% of my riding is in the UK so I use branded rather than Supermarket stuff whenever possible.

so it's an octane booster then?

"additives". bit vague isn't it? could be anything. fairy dust.

whatever it is, neither myself or my bike can tell the difference.

The better the fuel the better the bang the better the oomphhhhaaaaaaa
I to used to use Tesco clap but changed on the advice of a garage to SHELL, Car goes better plus more mile's to gallon,equals happy customer.

I think you mean Tesco have ruined the high Street

The additive packs are added in the tanker. Another factor is that Supermarkets might have a higher content of Bio Fuel as well and you will always get less mileage on Bio fuel. I think Morrisons has it at 7% where Shell is 5%.
Different companies have different additives but what they are I have no idea. Shell specifically states that their fuel gives better economy and cleans the engine/fuel system better. True or not? You choose for your self. I also don't remember ever having used any other supermarket fuel other than Morrisons so maybe Tesco, Asda or whatever is better. I definitely get a very large reduction in MPG on Morrisons fuel with the car though. Like I said before though I haven't noticed so much with the bike but the MPG is all over the place on that since some days its on the commute and others its blasting through the country roads. I rarely use supermarket fuel in it anyway. I will do some testing on my upcoming holiday tour since I generally get good mileage all the time doing that anyway so a duff tankful might be more noticeable.

It doesn't matter who's brand of Diesel I put in my company car, the thing can't go any faster than it actually does, normally a dash up the fast lane as quick as it can go, followed by slowing to 56 behind ATT and his mates trying to overtake one another, then another dash etc etc until I hit London and crawl for an hour to get to the client. Ditto the return journey.

As for MPG, who cares, the more it uses the more Nectar points I get, although spending £120+ a week on diesel for 3 years plus the weekend food shop has only just earned me £100 worth.

Some reward scheme.

Top tip: Uniparts diesel system cleaner is brilliant stuff and they sometimes have it on promotion at half price (as used in my wifes Mini Cooper D and my daughters Micra DCi Sport.)

hmm... so do I continue to fill up at the 24 hour Carlisle Tesco's at 1.35 for UL.

Probably.

I wouldn't.



But I live in Norfolk, so it would be a long trip just to get petrol...

TESCO CONSPIRACY THEORY

well i worked for the company for 30years
and yes while your sleeping we crept about the forecourt at night adding all sorts of shite to the fuel!!!
what a feckin lot of tosh !!!!!!!!!!!!!!

Its more likely that they are just chuffed to find somewhere to buy fuel! A case of any port in a storm!!

On the fuel side, or just a shelf stacker

I don't know what they do or do not put in supermarket fuel, I definitely get LESS MPG on it.

doesn't affect me. I only ever put £20 in at a time and have done for years. Therefore I've never actually been affected by any of the price changes because it still costs me the same regardless.
