Hi after recently buying my pd ive noticed that depending on where i fuel up determines the mpg and how long it lasts.

Ive tried tesco's own and tbh made the car abit lumpy and seemed to use it quickly. So i decided to then try esso and there super diesel which has lasted well and improved my mpg back up..

 

But after advice from fellow diesel barge owners ive been recommend shell diesel nitro+ as apparently lasts the longest and has the best return. But is it just me maybe as i used to own petrols and not used to a diesel.

 

So where does everyone else fill up and use?

SWMBO's Fiat JTD coughed and banged for years on Tesco diesel ( it was near her workplace ) and I tried every fix I could (apart from changing the fuel - DOH!).

 

A change of job location saw her filling up at BP (on their standard stuff, no fancy low sulphur or other pricey ones).

 

Whaddya know? A clean running 1.9 with no need for diesel additives, injector cleaners, cleaning the EGR or any of the other stuff.

 

Bottom Line  - Tesco diesel sucks & premium fuel is only worth it if the mpg change is better than the price change.

 

 

 

 

I mean:  My petrol SEAT does 6% more mpg on Nitro+ than Shell 95 (but it costs 9-12% more so it's monetarily uneconomic)

Does it really make that much difference? 

 

I've got a PD T5 and nothing seems to make that much difference. Proper diesels seem to run on anything imo, and aren't too fussy. 

 

Having said that, my regular filling station is Esso.

true my astra petrol would miss when filled up at tesco and i always joke they watered it down but its nice to know its not just me whos had trouble with tesco fuel. Problem aswell is alot of essos are now fuelled with tesco tankers so esso are probably just as bad these days.

yes and know tbh as if you tried tesco fuel you probably would notice a difference but if the fuel is crap your find it will gel up in the filters which wont help with performance and starting.

Never really been a fan of supermarket fuel in any form tbh. 

 

But diesels tend to be alot less sensitive as to what they run on in my opinion. Pretty tough things aren't they! . 

They used to be tough

 

Old PSA diesels (like my AX) running on chip-fat even.

 

However, modern Common rail diesels run such high fuel pressures they cant deal with any contaminants, and TBH our experience with the FIAT/GM Mutijet motor over 100000+ miles has put me off diesel for life.

 

It's just so complex.  Really economic when it's working, but so many things to go wrong and get it "out of tune", MAF, EGR etc etc.

The PD isnt common-rail is it? . 

 

I agree though. New diesels get more like petrols by the day!

well i work on trucks so yeah can vouch for fact that yeah aslong as you look after a diesel engine theyll take alot of punishment. As for not being sensitive that comes down more to the fact it fires on compression and not a spark so a little bit of water etc shouldnt hurt it. So makes you wonder why supermarket fuel effects cars like it does so whats actually in there fuel.

V power or BP ultimate diesel are the best premium in mine, personally I favour v power but don't have any local. If I go standard Shell or Texaco are decent and return good mpg.

I avoid supermarket diesel at all cost, it just does not agree with my car (Morrisons fuel it was, never again).

You're right PD is not CR but it does have very complex injectors which would probably baulk at dirty fuel.

Bad diesel has knackered vans in my work, nearly killed my dads freelander sport, and probably helped kill previous cars of his.

i think, though have no evidence, its the very low sulpher content and increased diodiesel content is what does the damage.

father bought a RR Sport diesel recently, i made him peomise to always put decent diesel in it -Topaz, as its the former Shell stations - as i notice even my old non pd tdiduns better and better mpg on topaz than the cheaper alternatives..

Morrisons diesel killed my fuel filter in the Berlingo (filled it full of snot). Tesco I never use. Shell diesel gave me poor economy in all the engines I used it with, both standard and V Power (no difference at all). Esso and Sainsburys fuel give good running and good economy, while BP seems best overall (but no local stations for me).

I tried supermarket fuel without knowing once, I lend a van to someone and they kindly returned it full of fuel, the only problem was that when I drove it the next day it was running really roughly so I asked him what he had done to it and was told that all he had done was drive it and fill up with Sainsbury's diesel.

 

I filled up the next tank with BP ultimate and it was as good as new again.

 

I haven't used supermarket diesel since.

Never really noticed much of a difference. I could tell with supermarket 95RON Vs super in the VRS but not with diesel.

 

All diesels are made to a standard so there should be little variation between them. Saying that I'll try to use 'proper' fuel sellers like Shell if I can. Never used premium diesel yet.

Used nothing else but Shell V-Power since its introduction, firmly believe its the best fuel you can buy.

A lot of what you hear about supermarket fuel vs esso vs shell etc etc isn't accurate..

Having worked in a petrol station for a supermarket our fuel came from whoever gave us the best deal. Some days it came from esso, other days it came from BP..yes it wouldn't be nitro+++++ or whatever, but would be whatever you get from their pumps.

having worked at a major company oil distribution terminal for many years, I can say that if a tanker was loading for a supermarket,  the fuel loaded would be to the minimum British standard as required by law.

should a load be required for one of the companies own outlets, the fuel would be injected with additional additives achieving a better quality of product, that is the difference

ran our PD Fabia TDI on supermarket diesel (Sainsbury's) for 13 years and 135,000 miles with no issues.  Have the Octavia running on the same - again no real issues (other than DPF many years ago which wasn't surprising given the BMM was never designed with a DPF in mind and could well have been a sensor issue).

Likewise, but these days I'm on a BP lookalike place fuel, and MPG is a lot more on this stuff than any supermarket. Possibly it's due to fact that it's a bit cheaper per litre. But I found in nine years that Furby likes her fuel from any place and the sleazier the better. Tart

Local ASDA has diesel at £1.08pl .

BP services enroute to work on M8 have it at £1.17pl.

At that markup I'm presuming the detergents BP add to their fuels are extracted from panda semen, and unicorn tears?

Yes, and they're goooood.

End of the day I'm not sure why this debate rolls on when we can sum it up thus:

Supermarket fuel = bottom end, cheap, ok for some, not for others

Branded standard = better, bit more expensive, ok for most, take your pick.

Branded premium = most expensive, the best, although some say it's not worth the money.

Ultimately, try a range of fuels, do some comparison, use your favourite.

You will probably find that as long as the fuel you choose suits your car, there isn't much of a substitute for well thought out economical driving with plenty of advance planning.

The debate rumbles on because there are lots of people that believe there is naff all difference between supermarket fuel and branded fuel.

Which of course there is intrinsically, whether it makes any difference to their car or driving style is another matter. We always hear from people in the industry in these threads who know exactly what goes into which fuel (see above) so there is an actual difference as I and many others have noticed having used a range of fuels and compared. As far as I'm concerned this is one instance where you get what you pay for.

You hear a lot of people buy supermarket diesel because it's cheap and then blow £15 on a bottle of Millers to make it better, why not just buy decent fuel, will cost less extra per tank than a shot of millers, which you will no longer need.

Fill mine up wherever I pass when its empty, never noticed a difference at all. Pd105 and always runs sweet
