Scotland 2014 Discovery 4 3.0 SDV6 XS Auto Indus SilverDiscovery 4

Honest John in the DT is an advocate for the use and benefits of super fuels using cogent arguments that have convinced me. But like choice of car you pays your money and makes your choice. Hopefully it might prolong my crankshaft along with other components.

2010 Discovery 4 3.0 TDV6 HSE Auto Barolo BlackDiscovery 4

Hi, I always run Shell, then when it came available shell V power. My experiance was that when towing a caravan with my discovery 2 running on cheap diesel resulted in greasy black soot all over the front from the exhaust. Running on shell V power and it was very noticable how much cleaner it was, it seemed more torque was available too. I also never had any injector or starting problems in the 15 years and 100k miles that I had it. Just had the D4 a couple of months and that is now fully flushed through with shell v power

My local Esso garage is £1.459 for a litre of the good stuff, £1.319 for normal diesel. £1.459 is far too much like ouch. When Esso started doing premium diesel it was only 7ppl difference, it’s now 14ppl. That’s the killer for me.

I’m not convinced either. Friend of mine here used exclusely branded diesel (no supermarket diesel in his country) and still needed new injectors and shortly after he sold it needed major engine work, way more than the car was worth. I doubt supermarket diesel contributed to the demise of my D3, if those bearing shells are going to rotate they are going to rotate. I blame s Censored t design and manufacture, an engine should last more than 166k miles with servicing over and above what is asked for.

They are made to used world wide, I’m sure supermarket fuel is better than most in Africa and the like? I did try premium at one point whilst car was new and made not a jot of difference to supermarket.

They sell both types of unleaded


Rolling with laughter Rolling with laughter

That explains why they opened one in Derby!

Although a friend of mine reckons he had an issue with Costco Diesel, says it caused his RR to Breka down 2 miles after filling up, he had it recovered, drained and refilled with different fuel and it was much better.. So I haven't got the balls to put it in the D4 just in case..

I use their fuel in my crappy commute car though and seems fine (petrol though)

I know the additive fuels definitely work, I worked at Millbrook Proving Ground for a couple of years and while there we did lots of testing for BP.

We had an MAN Tractor unit, with a trailer with concrete blocks, then a straight bar, attached to an Ex Amy DROPS, then on the back of that we had a large Tow Dyno.

We had to cruise around the circuit at 26 MPH at certain revs and with a certain load on the Dyno,

According to BP (and MAN I guess) this caused maximum coking of the engine, We did it for ~40 hours at a time. they they tookit away to assess the coking and returned it to us with 'special fuel'.

we did the same again with different fuels a few different times, when writing up the results the additive fuels were much better and didn't coke much at all!

I only use Shell V Power.

Off topic, but I have had 2 high specification blueprinted engines built. A Rover V8 & an MG 5 bearing 1940 cc, by John Eales & Peter Burgess respectively.

Interesting both said they highly recommended Shell premium petrol, and advise against all & any "non-premium" supermarket type fuels.

Not quite the same but I had a Smart Roadster for a while and in that you could really tell the difference between normal unleaded and super unleaded. No difference between Shell and Sainsbugs super juice but on normal petrol it wasn’t happy.

I've never notice the difference with any diesel, performance or supermarket.

Have a shell round the corner @1.339 per liter fuelsave 1.439 per liter vpower.

vs asda @ 1.227 per liter on my commute. that's nearly £17 more per 70 liters on the vpower for no benefit that I can see.

I did find the good stuff meant the D3 ran smoother, right up to the moment the engine lunched itself. Rolling Eyes On the D4 it is happier on standard Esso juice cf Tesco, runs smoother and gets ~2mpg more, however as Tesco is cheaper it’s neither here not there.
