Today for the first time ever my vrs just cut out, I pulled up to a roundabout and the revs just died from idle, it started no problem 2 mins earlier and after cutting out it wouldn't start !

After a few attempts it finally started then all was fine, very random !

I think some **** must have gone through the pipes so might just run a few tanks of other brand fuel for a while.

I have (on the last two fillups) started using V-Power and have noticed an increase of nearly 4mpg using road trip on my iPhone. That's for the same journeys, same times, same speeds etc. Don't know if this is related to similar problems with the fuel or not. Never noticed any bad running etc and I don't use millers.

As it only works out at £4.48 extra to fill the tank with V-Power I'm sticking to that from now on.

Yeah, don't use V-Power and Millers together - not the best idea, as the V-Power contains some of the same additives used in Millers - primarily cetane booster.

If it's £4.48 extra per tank, you might be wise to trial a bottle of Millers. It's a fair bit cheaper overall and you may well find similar results to using a 'Super' diesel blend.

Used standard deisel, BP Ultimate, V-Power and now been using Fuel Save for about 5 to 10 tank fulls now. All I have noticed with Fuel save compared to the rest is an increase of MPG and not really noticed any changes in power.

Is it possible that using V-power mixed with Millars could have caused the ECU to notice the high Cetane fuel and adjust accordingly, and then once using a much lower Cetane Fuel Save, the ECU takes a couple of tank fulls to change back to normally running again?

Also is your car chip, remapped to run better on higher Cetane fuel mixes?

Only a couple of ideas as not noticed any big changes in power and I run a bog standard vRS and have run over 100,000 miles on different fuels.

Does usually take a couple of tanks when using a cetane booster, either through a 'power' fuel blend or an additive like Millers. As you say, the ECU needs time to adapt.

I have always used V Power shell since new now four years no problem

I have had a serious problem with SHELL in the past when the additive caused engine failure

It fortuanatley was a company Astra and in the 1982? incident had to have a new engine fitted

Big Companies, police fire and ambulance services got these replaced no problem free by SHELL

Private owners who could not produce fuel records got NOWT Just a big bill to pay

I could not dis SHELL on the present fuel 1litre more per tank thing ONLY it did take about six months of the 1982 thing to destroy the engine

Who knows, without risking litigation to say what I have said

Hey even my V Power stuff may be bad in the end, but so far I doubt it,

I think the 1982 ? was a leaner burn or something that caused the catasrophe

Before i found out the Octavia PD105 had been mapped, i ran a tank or two of V-Power and a Dose of Millers Diesel Sport 4. And it went like a bat out of hell.

Found out it was mapped, had that removed and I clocked a fair amount of mileage in it before selling it, and the engine never skipped a beat in 41k.

Ive used boggo shell diesel with out miller etc for 2 years and not had a problem.

i have some in just now, dont know if its all in my head, had tempremental boost problems tonight, after i stopped at lights, i pulled away and went round a bend, i boosted a little upto 30, and noticed it wasnt exactly boosting, got down the road some more and checked again and it boosted, not sure if i just wasnt paying enough attention so will need to see what its like tomorrow.

Morrison's diesel with Millers additive has been fine for me so far, touch wood.

I think it's called 'Shell fuel save' as your car will spend a large amount of time in the garage or broken down and under these circumstances, you are using very little fuel. Even though the customer isn't happy with the results, Shell can happily say you are using less fuel. The government is happy to as your car is in the garage, you are using public transport.... maybe it's a conspiracy, the Government and Shell working together to get cars off the roads and more bus lanes to fill the gaps....

LOL at some of the comments in this thread. I work for shell and can say that it sounds like a bad fuel batch. This would not be "bad" from where it was blended in the refinery as the fuel testing and labs we use are very accurate. This may be down to a tanker/roadcar that dropped off the fuel having some contaminent in it of could be some water that has settled out been sucked up at the fuel staion pump you may have used.

As you've said flush it through with fresh fuel and some cleaner and you should be back to normal.

I have run 2 tanks through my car, from 2 totally different filling stations 5 weeks apart with the same result. Poor running and terrible warm starting issues whilst seeing no improvement in fuel consumption. None of these issues are present when running any other brand of diesel as I now run either Tesco or Esso standard diesel without problem so Shell fuel save will be going nowhere near my car again. Reading other motoring forums, its quiet obvious that I am not alone so I think its far more than a dodgy batch of fuel.

There's also a far larger amount of people not complaining about the fuel on motoring forums, and personally I've not had any problems from any of the shell garages I've filled up from (every two weeks for years). So statistically it's far more likely to be a bad batch.

Of course, no one has proof. Just like to provide an alternative opinion

Its also winter so there's probably a few extra additives in the diesel at the moment to combat the cold.

Out of interest, how did you find this thread? Were you a member on Briskoda before this thread started?

Just wondered if this thread possibly appeared on a Google search about Shell Fuel Save?

Don't listen to him, he's in on the conspiracy. I think he's a bus driver.....

I do know what he is on about though as I am an aircraft refueller and we have to take samples from the tank on a regular basis to check for water and particulate contaminants but I guess it's very different for aircraft as if you have engine problems up there you can't just pull over and call the AA. Still, even when we do this, there are occasions when we find water in the fuel but that is generaly when the tank isn't brimmers. I also found out that using too much fuel finder paste turns Jet A1 pink!

Lol. Yeah you got me! I'm just a shell bus driver haha.

I knew it!

well last week. had 10 miles on the trip left so put in £20 or diesel fuel save.....gave me this

this week. 5 miles to empty left and same again £20 of Asda diesel (supermarket fuel)

you do the math? how can £20 from 1 station give half a tank (roughly) and show 125 miles to empty and another 165?

Different driving styles prior to fill up is what's causing that. Absolutely nothing to do with the fuel put in as it won't recognise it that quick.

Mine changes all the time despite using the same fuel.

It works out your range from your tank contents and your average mpg, so if you have a higher average mpg when you fill up, your range will be greater. You could put diesel in with an average of 30mpg and it will give you a lower range than putting petrol in with an average of 50mpg, but I guarantee you won't get what it says with the petrol in the tank! Not unless you count the miles it does on the back of the AA truck.

Just found this site after googling shell fuel save problems. I have a 2004 Octavia 1.9 tdi which I've owned since new, never any problems till this week after putting in shell fuel save diesel. The car cut out at idle then wouldn't restart for nearly an hour. Running very badly and cutting out. Its currently in the garage, the mechanic who looked at the engine said it didn't smell like diesel normally does. Looking at this thread I'm not sure wether its a bad batch or fuel save in general.

If it were the chemical makeup of FuelSave in general, the problem would have been fixed by now. There's no way a company as big as Shell could have survived causing people problems since February this year, not since the same diesel engines are used across the VAG brands (so Skoda, SEAT, VW, Audi all affected, and there's a lot of VW/Audi company car drivers who do mega-milage). My money's on a bad batch if anything, or just coincidence.

For the record, I filled up with Shell FuelSave on Saturday morning on a virtually empty tank (think I put just over 43 litres in a 45 litre tank) and have had zero problems with it running, starting warm or cold, or otherwise. I did a lot of warm starts in the car yesterday due to running around and forgetting stuff, going back home for it, etc, and every one of them was fine. Gave it a bit of stick on my way around as well and it performed fine, no better or worse than the Tesco fuel it's been run on for months. So neither a thumbs up nor a thumbs down from me really, it's not full of cleaners like V-Power is so not as good for your engine but does the job adequately with no running issues.

I haven't put anything but Shell in mine since about August last year. It's been running on fuelsave since it was released and I haven't had any problems.

Like Gavin says, sounds like yours is more coincidence than anything.

does any one else just use cheap arse asda fuel! I only use asda as its literally 30 second drive from my house and en route to the motorway. Never found a problem and consistently get 60+ MPG.
