Hi.
Having recently purchased my first Diesel Motor I was wondering about the differences, if any, of the Diesel available to buy at the Pumps. Forum Members by the very nature of what we do tend to use Diesel as a Fuel so I thought I would ask the following.

Are there any differences in the Pump Diesel available? I put it into three categories.

Cheap Supermarket.

Named Branded like Shell, BP, Esso etc.

Premium Branded like Shell V-Power, BP Ultimate etc.

Any opinions or thoughts?

Thanks.
Yorkie.
 
Never noticed any difference between brands or who I buy it off , diesel (DERV) has to be made to BS EN 590:2009 standards (this is the official UK standard for derv fuel).
 
Yorkie My last Pajero and now my Jeep don't run as well on supermarket diesel, but I have mates that see no difference.
Try them out and see what suits yours best. I also give it a Diesel Majic treatment every couple of thousand miles.
Both vehicles are +100,000 miles could be the difference...
 
my mrs vauxhall corsa eco flex will burn any kind of fuel and return goo mpg, in my ranger 4x4 i do not touch supermarket fuel unless im really desperate, i only use regular fuel and does me well!
 
I buy whatever is easily available, runs perfect on supermarket of premium brand.
But it does return better fuel economy on premium brand fuel, on a run around an extra 3 or 4 mpg.

Ive had diesels for years always used supermarket diesel without issue .Ford ,Vauxhall ,Volvo ,the only thing i would avoid is biodiesel .Very dirty and leaves a weird stain around the filler cap?.The premium diesels have been tested and proved to give extra mpg ,ideal for thirsty 4x4 user,s.And you,ll know if someone,s on the used cooking oil ,Landrovers smelling of Mexican food anyone:stir:
 
I run a 2015 Ford ranger which has an average MPG readout. I reset it on each fill and find premium fuels (V-Power etc) give no improved MPG but supermarket fuel has a lower MPG, 3 or 4 mpg less than branded fuels such as Shell and BP.
All my driving is on the same roads and routes so my MPG is very consistent on each tank full.
 
I only use supermarket diesel as a last resort, less power and mpg. Years ago a mate used to work at an oil terminal and although it all comes out the ground he said supermarket fuel was "gassed up". It was a term used for additives put in it, which apparently are cheaper than the fuel itself. So, I suppose they are effectively "diluting it down", hence lack of power and mpg.

I used to notice it in particular when I had a manual vehicle. On one particular hill round here the difference in power made a gear change difference, every time so not just a fluke.

As stated above it all comes from the same place at the terminal. Delude yourself if you will!

Yep, it does, all "supermarket fuel" comes from one tank, how about the non supermarket fuel though ? There's lots of tanks in a terminal.
And, what's added to it after. There's no delusion when with some fuel you can pull 4th but with supermarket fuel it needs 3rd. I ran the vehicle for 8 + years and that's long enough for even the most sceptical to be convinced.

And, delusion works both ways, so who's the deluded one :thumb:
 
It all comes from the same refinery Scotland anyway ,
But likes of shell etc add their additives etc
I tried both and paid close attention to mpg power etc and slightly better mpg with shell over supermarket , and on cold mornings I'm convinced that the supermarket felt that wee bit smoother running .
I know that likes of,the subarus didn't like supermarket fuel & some had engine light come on , after one tank of Shell or likes it would disappear ,
Run what ever you feel but I 2nd the odd treatment of diesel magic .
Good stuff

I think performance DERV motors need the better fuels. I have a couple of hyundais, and run them on local ASDA fuel, they have drunk this since new and never a problem. I have a 30 year old landy with the 200tdi engine. It will run on anything and expensive performance fuel make no difference to it, but a splash of 2 stroke oil every so often makes a huge difference. it quietens the pump down, and makes a slight but noticeable improvement in performance. It is about 190k miles now so not exactly a performance machine
 
I used bio fuel for 4 years in a kangoo van and it was fine bar 2 points the diesel pipe that links injectors softened and I got through fuel filters after about 1000 miles engine and pumps worked fine on it I changed van and sold the kit then ran my landy on used cooking oil only needed to dilute it with diesel in winter and change fuel filters regularly older engine seem fairly easy going with fuel but the more modern stuff can be fussy
 
difference between supermarket and shell is significant in petrol, can't comment on diesel
run a high performance or mapped turbo car and log the timing and fuelling and you can see it.

fill up with VPower or Tesco 99 and I can notice the difference within a few miles if going from empty to full
more power

diesels will also burn liquified coal dust so aside from the lubrication they will run on anything!
 
I usually fill up from Shell , and i noticed is giving me an extra +50 miles per tank over the supermarket diesel, in my VW 1.9 TDI
