Hi guys and girls.

I usually always fill up with Regular Shell Diesel.. if I'm not near a Shell garage (nearest is 8 miles away), it's usually Texaco.

I'm lucky if I get 350 miles to a tank, but it only ever accepts 38L at the pump. I'm aware there's a trick to get more in but not sure how to.

Anyway. Was feeling flush last week and popped in Shells Premium Diesel.. cost a bit more but wow.. I've managed 463 miles and the lights not even on yet, no difference in driving style, same mix of journey lengths.

Could also be the warmer temperatures? But was shocked.

Do you guys have go to fuels that you feel give you better MPG; response and power delivery?

Cheers!

Anything that isn't supermarket fuel really. I always try and use the same filling station as well (partly because it's local, and have been using it since I got my licence in 1992 (and rest of family have been since the early 80's!) - it used to be a Texaco, but is now a Shell garage. Used to use the diesel in my DIscovery, but now use the V-Power in the vRS, averaging just over 40 mpg on the commute - squeezed 45mpg on a steady run to Aldershot the other week

I will always try and find a Shell station if we are off somewhere and need fuel as well - supermarkets are always a last resort (same as motorway service areas - saw one the other week selling petrol at £1.25/litre!) - there will be nay sayers, but u have checked it in other care on a tank to tank basis, and the branded fuel always gets better mileage per tank than supermarket

I hate to rain on your parade but the anecdotal improvements you describe together with the astonishing difference in MPG cannot be attributed to the change in fuel.

Even fuel company marketing departments using the most wildly optimistic lab data do not make claims like this because the ASA would be all over them like a rash.

It's simply not possible, so you need to look further and deeper and over a longer time period.

It's a 10 gallon tank so yes, there's air in the system if only getting 38L in - with the cap open there is a little hollow tube inside to the right that if you press in with finger, or fuel nozzle it lets the air out and tadddah! - the extra fuel to get to 10 gallons will go in.

 

As millions of threads before have said, load of rubbish using fancy expensive diesel to improve performance and/or economy......................................

 

I get 415 miles to a full tank and thats a gtb at 2bar ish...........................

I've done the exact same journeys.. pretty much the exact same time of day.. same driving style. Tyre pressures remain the same.. nothings changed.

The two things too change are ambient temperature and the fuel I've used..

I see this raised a lot on the Facebook page.. and different people will swear blind by different fuels - so I just wanted to gauge opinions.

Maybe I managed to cram more in to the tank this time.

Quality Fuel contains Additives and cleaners which will be better for the Engine. It's the same as  buying Supermarket rubbish and then adding Millers yourself

That's what I do. I find it works quite well. Can't tell the difference between that and v power

V power wins for me whether it's petrol or diesel, however there's no v power diesel round here. My local is shell but only have v power petrol as they don't have enough tanks. Diesel wise I'll either use regular shell or Texaco at my locals or BP ultimate if I'm passing that way (20 miles away).

I avoid supermarket fuel my car hated it but millers did help flush it through. I don't feel the need for additives with regular shell or Texaco, car runs well. Sure the Millers probably gives me 0.2 more mpg on the overall but when you think it costs £15 for a bottle that does 10 fills it doesn't save any money. It also negates the value of supermarket diesel to an extent. It will however equalise cheap crap to branded fuel. May put some in once a year to clean the injectors but I won't lose any sleep if I don't get round to it, I put a fair bit of clean fuel through mine as it goes.

I get 61-62 mpg consistently round Wales on the overall trip, between 55 and 70 each journey (without additives or premium fuel).

BP normal diesel, had no issues with juddering and rough idle since i started using this unlike the asda fuel i used to use (used to work there at the time so was easier to fill up there :( )

 

100 miles for £10 more or less, mix of A roads and town driving, loads of short journeys too

 

tried BP ultimate a few times and noticed a drop in mpg and car didn't run as well, may just be the ecu still trying to get used to the new fuel though

The ECU can't tell what fuel you're using, it has no way of knowing, you could use chip fat and it'd be none the wiser. This is one of the reasons why premium diesels don't really make any difference, you'd have to remap using a rolling road to make any use of higher cetane numbers.

Shell V-Power every time.

Ive just put 50 litres in my fabia. I run it on anything and returns 65mpg with map. Iast fill up I did 45 litres and got 467 miles before light came on.

Years ago I worked for a firm who supplied me with a Golf SDI. Didn't matter which version of Derv it got, it ran as well and returned same MPG. My present car has no complaints on where it's food comes from. Always roughly the same MPG/same miles per £10 of fuel.

Re post #3.

A Fuel Producer & Retailer is running adverts right now making claims, and i see no ASA action being taken right now.

So not all over them like a rash....

Oh dear, a 21 mile per tank improvement after 6,200 miles under lab conditions is hardly the same as 113 miles on the very first tankful that the OP is claiming.

I don't deny that the cleaning additive packs in premium fuels do improve cleanliness EVENTUALLY, and high octane petrol allows the ECU to run more ignition advance which improves economy and torque. But not diesel, no.

21 miles per tank extra maybe because they do not want to make 'wild claims',  but then any driver can try and see, 

and maybe better that, car / engine dependant.

 

But no ASA all over them right? or so far.

 

and with a car that runs on petrol we do at least know that many can benefit from 99 Octane, running more efficiently with the 5 pence a litre more over 95 ron , (Tesco Momentum 99)

or £2.25 a tank extra (equivalent to 2 litres) might give 2 or 3 MPG improvement, so pay for its self, 

not only in a smother running engine, but also less need for consumables.

 

The thing about pithing on parades is if you have a car that might benefit from a more premium fuel, higher octane or cetane or just Detergents (Sodium) and you drive and buy fuel it is cheap enough to find out yourself if there is a benefit.

You have all year, several seasons, many miles to cover and keep a track of fuel use and weather, and car loaded or not.

then with petrol, there can be benefits with 100-102 octane over 95, 97 or 99 minimum, just it costs lots more in the UK 

than on Mainland Europe.

(Winter fuels in the UK between Oct / Nov & March, sometimes later dependent if in the North or South and what is brought in from Europe and still in stock, so you can monitor MPG and running and see if you feel or monitor the difference.)

You're talking rubbish, I've given you perfectly good reasons why it doesn't work the way you think it does.

Good, you will not be buying any special or premium priced fuels then, basic is fine.

Use Veg Oil and Drain Cleaner and make your own Bio to run a diesel on. Pay no Tax or Duty.

You might get the same Cetane Rating as the Posh Diesels.

 

95 Ron will do fine as well if running a petrol.

Do you have the receipt? How much more did it cost? 

Just wondrin if you managed to accidentally vent the tank, and filled it with a few more litres than usual?  Commonly happens if you have to use a pump on the 'wrong' side of the car, where you have to drape the hose around the back of the car and the nozzle goes in at a bit of an angle.

^^^^^

As much as 7 litres more in when you vent.

Just to clarify.. as it seems to of been misconstrued above. I'm not trying to make any 'out there' claims that Shell V Power is that much better for your mpg.

My point was.. that from my last fill up at a Texaco using there bog standard diesel, I managed around 350 miles.

I needed fuel when visiting family, and used there Shell garage, and doing no extra journeys, the same commutes, I seriously haven't changed my driving standards or how I boot it - I managed 471 miles before the light came on and I've refilled.

@Wino - I don't have the receipt, but I know it was £52.01 from my bank statement and it was £1.20/Litre - so that works out too 42.9L? I know the trip isn't a solid source, but my average MPG over the past 1500 miles is 43.8.

The extra 4 litres would account for maybe 50 miles? So maybe that levels out what I'm trying to say.

My original post wasn't intended to be as it's been taken - I just wondered what people's opinions were on the fuels on offer..

Mystery partly solved I think. 52.01/1.20 = 43.34 litres. That's 5.34 more than 38.  Should have taken you approx. 50 miles further than usual, if not more, even if it was the same fuel as before. Was it 'reach around' fill-up, can you remember?

 

I don't use diesel so I can't offer anything useful on the different types available.

"high citane number" fuels are lubricants for serpentes!

 

"Premium DERV" tends to be concerned more with completeness of combustion than changing energy density, and in any event the energy density of citane is inversely related to citane number but premium DERV tends to be higher citane number.

 

If you've just swapped from winter to summer diesel, and did a single atypical trip (by your own admission you don't normally fill up at your relatives' local) that could cover most of it.

No - never reach around to the fill up, never will! I do remember it clicking off when it had only just started filling - as if it was full.. adjusted the nozzle and it was all good then.

Ah well - case solved.. didn't really notice the Litres I put in, was more shocked at the price lol.

I guess the extra 5L and a variance in gear changes etc could account for the majority..
