I’ve given up caring.

But I very rarely fill up at a supermarket. I won’t drive the extra miles for the sake of saving a couple of quid.

Just use my local Texaco garage as its most convenient. They don’t have a super diesel pump just regular diesel.

I put their 97ron in the M3 because it gets filled up once a month and it seems to run a bit better on it, I have put the Tesco 99 Ron in and it’s a bit better, which is the same octane rating as shell, but BP do a 102 octane fuel...... might drive to get a few gallons of that next time I need to put some in to give it a go...

When we had the ill fated SC, it was nothing but V Power.. then someone told me don’t put it in all the time, it’ll be counterproductive. Not as precious as to what diesel supplier it is anymore, usually buy based on nearest fuel station location, although do make a point of putting VPower in now and again... so maybe still a bit precious 😂🥱

People forget that cars are designed to work across the whole world, and that engines also work in parts of the third world where even if refined properly, chances are its stored in a really shonky tank at the petrol station.

for that matter, how many farmers here run their range rovers on red, from the dirty tank at the bottom of their yard. even more so their tractors and lorries which have some real emissions gear and very sensitive injectors, not lke the fairly basic roadcar stuff.

Lots of uk high end cars get exported to bits of africa and south east asia.

I'll take my chance on whatevers cheapest, fancy fuel is as well marketed as bottled water.

Emissions requirements are different in different markets - there are Range Rovers built for African markets which only meet Euro 2 emissions standards, ones for parts of South America which meet Euro 4 etc.

Aside from the detergents, some premium diesel has a higher cetane rating too, although quantifying the benefit seems difficult.

Hey guys,

Has anyone had experience with running only Shell V Power in their car and did it make a significant improvement given the increase cost compared to supermarkets own diesel?

I use Asda fuel in my car and periodically use a fuel additive cleaner, but I am thinking should we protect our FFRR investment by using a premium fuel?

This was the original post - how did we move on to whether or not cars meet various emission standards and how is it relevant? fuel is fuel regardless of wether your car is Euro 2,3,4,5 or 6 the good news is it's not possible to buy fuel in the UK. Geoff

Actually no, fuel is not fuel - pre-euroXX diesel engines were designed to use diesel with sulpha to lubricate the pump & fuel system, also IIRC to preserve the seals.
One of the reasons why people with "old" diesels add some two-stroke oil to their fuel.
Diesel has changed over my motoring lifetime - virtually no (if any) sulpha in it at all thesedays & a certain amount of bio.

So, we can start arguing about additives now that the steam is running out of this thread. 2003 Range Rover Vogue TD6

“Fuel is not fuel” now I’ve heard it all Geoff

The point is that cars are not designed to work in every market - there are regulatory differences which mean different emissions controls. There are also relevant differences in fuel quality around the world.

The additives in more expensive diesel are the most relevant difference in the UK.

Back in the day, when I had my S max (diesel), we went to France dragging a 5 berth caravan behind. I filled up with "cheap" French supermarket fuel when I got over the channel. I thought the car was running a bit rough with a fair bit of smoke being emmited from the exhaust. Once I got back home the car became smoother after I filled up at my "local" supermarket! Previous cars:
S-Max 2007-2013 (only diesel I've had, good car but expensive when diesely bits go wrong, so what's the point?)
Galaxy 2001-2007
Mondeo Estate 1997-2001
Sierra Estate 1993-1997
Uno Turbo 1987 -1993
Fiesta 1984 - 1987
Fiat 127 1982 - 1984

I use French supermarket diesel all the time and my car runs very smoothly with no smoke. Even when booted to clear the cobwebs.  John

Big lazy truck engines are fine on low-cetane rating fuels - as long as it's clean.

What do you think a Range Rover lump is, high performance

When I did a period of lorry driving, on the return to the yard you filled up at a certain Shell garage for regular only (I tried to get the points but the guy laughed and said discount had already been applied ). All his trucks were remapped but equally it may be an accounting thing. Personally I use just Shell regular with a very rare treat of V-Power diesel. In my nerdy world if I’ve thrown in Morrisons diesel in the car, it is fine but MPG drops by a couple of miles. visiting from www.rrsport.co.uk
