Carrefour selling 'superior' diesel (1 Viewer)

I noticed recently that Carrefour has started selling 'superior' diesel as well as the standard stuff
I'd normally avoid filling with supermarket fuel having had a bad experience once, but I've used the 'superior' stuff a couple of times now without issue.
Can't remember what they're calling it - anyone know?

I'll let you know tomorrow after we've stopped at Carrefour in Narbonne for a fill up.
I use supermarket fuel almost all the time and not had any problems yet.

Hi Richard
Don't think they're selling it in all stores - maybe only the bigger ones
We noticed also that Carrefour have just opened a brand new petrol station opposite on the ring road near Citie Europe - bought some 'superior' diesel there the other week

Don't know about French diesel but last 2/3 tanks have used UK supermarket juice, my impression is that I am getting less MPG.
Just a thing of mine, always keep track of it.
Emissions must be OK as I had MH MOTD Monday,
But less mpg.

Diesel is made to a standard. If you pay more you might feel good but what is the real difference. In Germany yesterday I saw normal 1.13e super 1.26e and something called Race diesel 1.54e.

I don't think a delivery van engine need premium fuel.

Exactly. It all has to meet EN590 standard. Supermarket or branded. It frequently comes out of the same storage tankage as well. The branded stuff may have a few parts per million of an additive or two whereas the supermarket fuel has a few ppm of slightly different additives. In each case the MPG will be the same or at worst statistically insignificant differences. Someone told me the other day that he only spent £30 per week on Shell fuel where before he was spending £40 on Tesco stuff; told him to look which tankers keep pulling out of Vopak Thames terminal fully loaded and asked why people were not queueing around the block for Shell fuel (I know I would) if it was 25% better economy. Shell claim an "up to 2 litres per tankful" i.e. 4% maximum and impossible to measure outside a test rig in a lab........ Smoke and mirrors.

Superfuels are different and certainly worth using every now and again for their much better (above bare minimum) detergent qualities, if not necessarily regularly.

I've just retired from spending the last 30 years working with fuels and fuel blends/quality............. especially good old diesel fuel and heavier fuel oils

I think all foreign fuel is better quality than here in the UK.
I have done the maths and foreign fuel gives 1.609 times more MPG then UK fuel.
I love watching the miles go by on the roadsigns and marvel at how much further I get on a tank full.:)

After @Robert Clark started this thread I filled up with the Carrefour 'premium'? fuel at Cite Europe to see if it made any difference to economy or performance.
For the next couple of days I had the worst mpg figures of the whole 2k mile trip.
Could have been coincidence but I don't think so. The thing that affects mpg most of all seems to be strong head winds rather than load or terrain. Those couple of days had light winds, easy low speed driving and no motorways.
I went back to cheap supermarket fuel afterwards and my usual 26mpg (ish) was restored.

What size engine have you got Richard?
We average about 30mpg between fill ups on 'regular' diesel, in our 150bhp, manual.

Dont agree...I get less mpg from a gallon in the US than I do in the UK...:)

I filled up with superior petrol a few weeks ago simply because the shell garage didn't have normal premium. I thought this would be a good time for a comparison test as I normally use supermarket normal fuel so I used shell superior at the next three fill ups. :(
Didn't notice a single improvement over that period so guess what....yep I am back using supermarket premium grade and happy to do so.(y)

I occasionally use the 'Superior' fuel, but not for an improvement in performance, but to hopefully help keep the engine clean.

150bhp but with an auto box.
I log our consumption on a phone app and from new we have done just under 16k miles @ 25.81mpg.
I think the mpg is improving slightly as the engine loosens up but I can't get near your 30mpg for very long. :(
Mind you, I'm not known for being a 'dawdler'. I'm usually pretty close to the speed limits and if you stick closely to the 80kph limit on single carriageway roads in France (4500kg) you will soon get an irate HGV driver right up your chuff. ;)

Hi Richard

On the motorways and major roads we do 90km (60 mph) maximum. I tend to use cruise control.
The only time it drops below 30mpg is when there's strong head winds, when it drops to 27mpg
I'm using the dashboard to give me fuel fugues - wondering if an app would be more accurate?
Which app do you use?

Nope, sorry....it is all brewed to the same standard using identical components which are mostly purchased and brought in.

This one:-
Fuel Economy Calculator by Corbenic Consulting


Not the best app but it works.
I think the Fiat dashboard computer is pretty accurate but I haven't done any sort of long term comparison.

Mine was reliably more than 2mpg before blanking the EGR and now 1mpg over calculated

Believing the instruments
They are notoriously optimistic
Are you suggesting that a vehicle manufacturer would mislead its customers regarding performance or fuel economy ?????

I shall carry out an experiment to test your hypotheses
