I usually run mine on BP Ultimate or similar, some times use the regular variety. It even ran OK on French diesel. Just for a change I thought I would try a mainline supermarket brand to see if there was any difference.

Rough, noisy, less pull, about 4mpg less etc.

I have the SD4 auto and usually get about 36mpg or if pushing it around 34mpg. With the supermarket fuel I was only getting 31mpg.

The above has convinced me to carry on using BP, Shell etc.

Never go anywhere near supermarket fuel for the above reasons, I'm using Shell V power or whatever it's called with good results.
Can't get better than 32 mpg though (auto). FL2 SD4 Metropolis Auto Santorini Black / ivory completely stock.

It's true that light travels faster than sound, some people look quite intelligent until you hear them speak.


Stop global winging.

If you look at the pumps (e.g. Morrisons) they do tell you that their diesel fuel is mixed with biofuel - can't remember the proportion but it exceeded the tolerance recommended for the Jaguar 2.2D engines. No Longer the owner of a 2013MY Fuji White GS

"Fiat Lux" a philosophy not a car

There must be plenty of folk with rough running cars then because they queue down the road for it at certain times of the day because Tesco offer 4p off every litre when you shop, so its that folk go for, whether its rubbish or not theyve saved 50p on a tankful.
I always use the premium hot stuff, dont know if it makes any difference to the running but it supposed to be higher graded and I think about it might be better for the DPF? as it hasnt given me any trouble as yet, so I will carry on as I am.

My cousin runs transit pickups delivering logs and an fl2. He refuses to use supermarket stuff after many issues, but he passes other brands on his log rounds.

I use morrisons 75% of time due to lack of choice in 10 mile radius and have no issues.

all my vehicles well filter serviced maybe that the difference, my cousin is a 'mend when broke' type of operator.

Used Tesco diesel since day one, with maybe the odd cheeky tank of Sainsbury's thrown in from time to time...

Never had an issue with anything engine related (except for a minor oil drip), but I'm pretty sure that comes as standard equipment on a LR......

Runs great.

Can't say I've ever had any problems with supermarket fuel, though the past couple of years I've been using Shell as they have been price matching Sainsburys (in this area) and I have to drive past Shell to get to them.

It's usually just the bog standard Shell stuff I put in unless they offer triple points on the V-Power. 21MY Defender 90 S 3.0 D200

I have 2 FL 2 190BHP auto. you should hear the difference in the idle and rev between the one running the usual high quality diesel and the other when I has the supermarket fuel in it. It was 'orrble and lumpy and sounded like it had a compression knock.

Both are 2014 cars - maybe react differently to the 150 BHPs? We intend to keep them both for years so I do want the best for them to protect the engine, fuel pump, injectors etc

I run mine on Waitrose supermarket fuel no problems at all, though it is branded as Shell, I have never noticed the difference between fuels but I don't use the super versions. The Freely does allow a higher proportion of bio fuel than most and certainly above the UK norm, or at least the later ones do. my PC is slightly to the right of Genghis
