I drive a 2013 BMW F20 125d ... with regular supermarket diesel, it averages 48mpg or roughly 520-540 miles per tank. With Shell V-Power Diesel it averages 55mpg and gives ~620 miles per tank. I've used supermarket fuel exclusively in the past and paid the price for it with needing replacement EGR valves / carbon cleaning etc.

Ode to have V power Diesel at 109p a litre rather than the 186p I'm paying now.

"Now everybody is going green". Just thinking of the VW case last year....

Guys , enjoyed your video , but there's a huge thing you left out, if you run your car on normal diesel then switched to v power you don`t notice the difference till about 4/5 weeks as it cleans the system , then you notice the difference in sound of the engine +power + fuel economy, then you appreciate the 4/6 pence a liter more , car is faster more responsive and actually more economical, i have tried and proved this with r master van 2.5 dci , r scenic 1.6 petrol and a 25 year old prelude 2.0 16 v petrol, sorry but v-power rules , i wont use anything else anymore , btw over 8 years testing

I love v power diesel makes my car feel more responsive, smoother, quieter and abit quicker

They should have run one more test with "supermarket diesel" *afterwards* and see if the engine still made the slightly increased amount of HP…

Very nice!! I already knew that, but its nice to see a practical test. Thanks. ;]

For diesel yes, this is significant but the REAL reason you run them is a) to clean the engine of current cheap fuel buildup b) reduce engine smoke which makes EGR's and DPF's fail c) Make the engine easier to live with, less dead spots etc. d) Better MPG after a few tanks worth. This is, undeniable for diesel. Not so much with petrol as its already pretty clean and naturally astringent.

Back in the days when labour were in power and diesel was less than a pound a litre. Good old days

I wish it was still 100.9p per litre :(

Shell v power is so worth the money and works almost instantly

Thats why i love diesel! It evolved so much and reached perfection. It has torque and power. Not like petrol which gets evaporized before reaching the combustion chamber...

Cab driver here I’m doing around 40k miles a year, i always use shell v power diesel because after testing a lots of fuel brands, V power is definitely the best for me. Beter M.P.G ( around 3 to 4 mpg difference) Good Power ( I can feel it ) Less engine vibration Less noisy Less carbon, emissions. Even smell better, 😂 And always maintain fuel system clean, never had DPF , EGR issues etc.. Also lots of shell club card points. Other drivers in my company use cheap brands fuel or they don’t want to put expensive Shell V power., But they want to spend thousands of thousands on repairing costs end of the year. And I have proof of that. Honestly guys I can’t understand that. Thank you Shell 🙏🏼

possibly because the engine was warmer but still i believe these fuels work just not on the first gallons.. they say it takes a couple of tanks of it to start making the effect (to clean up the engine)

@baldandold torque is acceleration, but you have to look the area of the curve that you get it. hp is speed. Kinda like of like the difference between how fast you're traveling when you hit the wall (HP) VERSUS how hard you hit it (Torque)

I have put she'll nitro in mine Picasso today - and iam seeing a massive improvement on mpg already compared to supermarket fuel 10+ mpg according to my computer - engine seems more responsive and runs a lot better - I tried bp top stuff last week although an improvement on mpg 8+ the shell nitro is winning so far .

thanx for the upload

I put in premium unleaded in my fiesta, the throttle seemed more responsive, but not particularly any faster

3:01 "...loads of cetane...a chemical that..." No. Cetane, as it pertains to diesel fuels, is just like octane for petroleum fuels: it is a rating that pertains to how difficult it is to make it bang. There is no cetane in diesel fuels.

If you do have a diesel one of the best ways of returning it to peak performance is de carbon treatment (Terra Clean). I'd recommend it at perhaps 50K and 100K. I notcied a difference even though I use BP Ultimate. In BHP it's only gonna be single figures. But removing carbon in the EGR could make it more reliable?

I watched the petrol one of this show yesterday, with the grey haired chap. He said line for line what Tim said at the start of it, but he tested 3 different cars with the 3 fuels (petrol) Wow I remember it around a quid a litre. My dad said back when he started driving HGV’s it was about £1 for 3 gallons !!!!!

Don't really give a damn about that pseudo-power-gain, which I never believed anyway. I am however interested in the cleaner and more complete burning of the fuel.

@MegaMaster456 but you save much more fuel with diesels, so you would spend less on it than petrol

I drive a 2013 BMW F30 330d and always buy V Power diesel. If the V Power produces 6 more BHP in a normal car like the citroën, it should produce more in a performance 6 cylinder diesel.

I run my 535d and my 184fr Leon on the v power diesel.

v power for £1.09/L omg back in the good old days 😢

Imagine being an automotive journalist and getting scared about 155bhp 🤣

The most important point for me is that the V power Diesel does not contain any ethanol.

I’m currently got ASDA diesel in my Fabia at the moment as the fuel station in my area has been closed for rebuilding, delayed due to COVID, and I really miss the V-Power. I also use the Esso and Texaco versions but the V-Power runs smoother. Now it’s full of blank spots and rough idle.

I paid 0,70 Pounds yesteday for Shell fuel saver diesel.. (Denmark). 2016.01.05.

Omg V power used to be a pound a litre ? 👀

but is there any difference in MPG??

BP Ultimate is the only fuel I use on my 2.0 tdi after trying all other brands , they are all rubbish and the car runs unevenly. BP !

I usually pump regular uls diesel but when ever I put vpower diesel it definitely has more umph

I use v power diesel from shell and I can see better mpg plus is better for injectors. Tdci engines don't like poor quality diesel

Cetane is a property and not a chemical.

Is that car sausages Tim?..lol and they've pinched the soundtrack !

This test did not demonstrate whether you get any efficiency saving. How do the increase in power figures translate to additional mpg to reveal whether they save money?

In Australia you can only buy the premium diesel from BP, Shell and Caltex but you can find the regular one from independent retailers

Does She’ll v power and BP ultimate, reduce fuel consumption?

@godjp821 yup. diesel cars are much better now. If you asked me what diesel vehicle I would buy, my answer would be the Audi Q7 V12 TDI.

I could care less about an extra 8 horsepower. do they run any cleaner? How about three cars running that same test 48 times a day for the next few months, each on one type of fuel? Does the more expensive stuff create less carbon deposit or clog the injectors less?

Is the extra hp due to the fuel or the fact that the engine was running a little bit warmer following the first test?

Is esso supreme diesel any good.?

sorry forgot...300ml oil per 70ltr.

Perhaps one of the big fuel companys could develop something that cheats your engine into thinking its cleaner and more efficient. Ooops , sorry, VW are way ahead of me on that!!!!!

I love how they bash diesel cars, when a proper diesel car can be an absolute beast... An Opel Corsa diesel is shit, but a car like my E420 is amazing. Upped the power to 390hp and the torque to a whopping 920Nm... That thing will do 0-100 in 5 seconds. That's enough to keep up with sports cars and she'll keep going all the way up to 260kmh. I love the look on 3-series owners at the lights, when this big, diesel, grandpa-sedan E-class pulls away like a rocket and they are left in the dust. Proof that you can have fun with a diesel.

Is esso premium diesel any good?

id like to see the full figures, especially the torque figures, as diesels are not BHP rockets, they are low revving torquers, and its torque that moves cars...

Cetane is not a chemical.

Guess my next tank will be premium

actually the engine will have heatsoaked after the first run and the second and third run would of produced less power

On the dyno, wouldn't it produce more power to rev in 1st gear rather than top as that minimises frictional losses in the gearbox and wheels?

The bit I don't understand, fuel prices have rocketed yet so has the extra cost of premium. The additives wont have gone up so why are we paying 11-15p/l extra??

I'm sure a professional tuning company wouldn't be aware of that :P

Should've tested the torque figured.

oooooo this hasn't aged well

Funny now 2018, diesel in Europe now on the nose.

@tyrannical rx8's have 160lb-ft

TEST OF DETERGENTS - diesel is a natural lubricant and I’ll be curious to know if added detergents in premium diesel could reduce that lubrication by cleaning it around the piston rings unnecessarily. This will result in lesser lifespan of engine. I personally feel my Diesel engine runs smoother and quieter on regular diesel. Any other thoughts ??

ask Audi, - theyve won Le Mans with a Tdi, or JCB, who went 350mph on the salt flats, again, with a diesel. or the Maltese TruckDragsters running with Nos on truck engines...

sort of misses the point for your average van driver... the point is keeping the fuel system clean

If you really want to clean out your fuel system and restore lost stock power use the American bg 244 diesel cleaner or 44k for petrol engines.Its the best stuff on the market but its very expensive.But you get what you pay for.!!!.along with high quality fuel shell v power or Bp ultimate.All of the above will work better, pound for pound with a good remap of the engine's ecu.

Now look, better on fuel, better engine life, everyone wants a diesel. Very tuneable engines as well. I wouldn’t go back to a petrol.

@baldandold Diesel has a narrow powerband. My VW TDI makes it's torque from 1800-2200. Hp peaks around 4000. My RX8 makes it's power from 5000 to 8000. Wider powderband, it's a faster car even though it's got 130 torque vs the TDI's 230.

its torque that moves cars, not horesepower

This is meaningless. You picked up a 3.8% power increase. Such small differences can easily come up in multiple dyno runs on the same fuel. So there is no proof here at all. Also, cetaine is a rating, not a chemical

BP isn't plural.

u want to get more bit of power and clean the engine...use regular just add 300ml of oil 2 stroke mineral into tank before filling ....enjoi.. will take 2..3 tanks to clean engine...and diesels must have oil catchers....some do some not...

Now they tell u to ditch everything n buy EV 😂

anyone who buys a diesel and complains about power , is not a diesel person.

what engine had that citroen got 2.0 or 2.2

This guy got v power for 100.9P It’s 184.3P near me

Who cares about bhp in a diesel? Is all torque.

kinda not happy pumping it in tank for 1.48 pounds per litre...

That car should produce 138hp with supermarket fuel not 155! Are they testing an already remapped DW10B ?

100.9p per ltr.....wow in 2023..that now seems like its a give away..lol

a Veyron would benefit from premium fuel I mean the car has 1001Hp + 7% that is 1070 Hp

OMG its not bhp at the wheels!! Bhp need to be measured from the crank!" Even thou its a hub type dyno its still at the wheels!

watch?v=fPW1GfnoFyM You have to activate the english subtitles.

Supermarket fuel are dire quality

Once i put bp ultimate ...and what can i say...yeahh i run much more miles ,km or whatever ,but the best thing ,ultimate turns my fiat into a ferrari...🚀

Not worth it

v power non sense, as long as you keep your car serviced with the right oil, that's all that matters.

I noticed my Aircondition was extra cold when I use premium diesel in my vehicle

For diesel yes, this is significant but the REAL reason you run them is a) to clean the engine of current cheap fuel buildup b) reduce engine smoke which makes EGR's and DPF's fail c) Make the engine easier to live with, less dead spots etc. d) Better MPG after a few tanks worth.
