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.
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
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.
A) Myth, that's why they have diesel filters. B) DPF can be cleaned, cut out physically and replaced/cut off and straight piped or turned off via software. So none of what you said applies anymore.
@@SuperLC1010 not legally, you're essentially cutting out what mare diesels unreliable. Without these environmental add-ons, diesels are very reliable and you don't need additives. However, in this day and age, with these as standard and legally required, you do need them.
@@SuperLC1010 - Whilst it’s not illegal to remove a car’s DPF, it is however illegal to drive without it if one should be fitted. The fine is £1,000 and a car without a DPF will automatically fail an MOT if it's spotted.
@@Jimbo8012 as an owner with 200+ k miles on the clock an EGR Delete and DPF Delete, i have never once been flagged at MOT Time, and it ALWAYS passes emissions. Okay so i have to put a diffrent ECU in it for test day, all the components are there, DPF is gutted its just a box, ECU is remapped anyways, egr is disabled and blanked. Even if i MOT'd it with the modified MAP, i believe it would still pass the MOT and Emmissions.
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)
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 .
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...
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.
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.
@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)
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 !!!!!
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 🙏🏼
Assuming you drive something with a HDI engines like the majority of the drivers in my area, I run a 2.0 HDI 16v 136 and I achieved over 750 miles to a tank of Esso Supreme+ which is 100 miles more than the stated miles to a tank. I averaged 58mpg from a 307 CC HDI.
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.
In my opinion asda is one of the worst in my last car I always ran BP ultimate but when i was stuck I fuelled up with Asda and on a cold morning the engine was noticeably more noisey and not as lively
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.
It isn't a performance anything. It's still a same principle diesel engine, but with more cylinders, it probably gets less power than the 2.2 HDI from it's displacement. Peugeot are pioneers at diesel engines. The Germans are still learning from them.
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...
+Phen0mable I usually get 700 miles of motorway from a 53 litre full tank, had no choice a few weeks ago but to buy supermarket as it was the only place open at silly o'clock, I only managed 500 miles :( it's back at 700 now I'm back using normal diesel took a few tank fulls to flush out the supermarket stuff though.
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?
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??
Charles Macgilchrist most engines limit torque in 1st gear, and also chances are you will wheelspin with max torque. So when you overtake in 3rd or 4th gear, you need to be able to squeeze that gains then
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?
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!!!!!
@@qasimmir7117 complete opposite to my diesel. Doesn’t smoke, doesn’t clatter and doesn’t take long to warm up either. All depends if you look after it.
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 ??
H C The problem is the smokiness after burn when diesel is ignited. If there are no detergents then it eventually clogs up the DPF, EGR valve and fuel rail sensor. Ultimately in the long run it leads to expensive repair. I now go to garages all the time and avoid supermarket diesel, following costly repairs, that my mechanic put down to "shit" diesel that I used.
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...
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.
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...
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.
Gonna be fun trying to have your 3-series... You seem to do 0-100 in roughly the same time. Tho if we ever decide to race our cars, do come to Bulgaria... Fines in the UK are too high. And I'm pretty sure I'd be fucked in Germany, cause I got rid of the DPFs and fitted AMG pipes for better sound. And this kind of fun is illegal in Germany.
The 7G tronic can handle 900Nm and I added a secondary cooler to make sure the ATF doesn't overheat.If you don't drive like Jeremy Clarkson all the time, the extra torque won't do any damage.
Seriously? Damn... What car and engine do you have? Guessing it's a TSI. If it's a smaller petrol engine, maybe it's paired to a smaller and weaker transmission... Mercedes in the mid 2000s had two automatics. 7G Tronic - 7 speed - max 900Nm and two 5G Tronic - 5 speed - Small one can handle 700Nm, large one (for V12s) can handle well over 1000Nm.
Torque at the wheels, yes. But torque at the wheels is a product of the engine and gearbox combined. I can generate over 500Nm of torque by bouncing on a 3ft breaker bar, but it's not going to do anything in terms of acceleration.
@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.
High performance cars like this will already be tuned for High Octane fuels, as such when they are run on normal fuel they will have a drop in advertised power (lower octane than tuned for --> HP quoted with premium fuel)
Yes I agree with Barker. A Veyron is probably recommended to be run on posh petrol anyway. If you can afford a Veyron the extra 7p per liter of fuel is going to be the least of your worries. A country going bankrupt would prob be a piss in the ocean for you to bail them out. It would run on normal petrol because it has to legally but you may get knocking problems etc.Running premium fuel would not result in 1070hp, like 1001hp isn't enough for any public road anyway.haha
***** Hi there For the purpose of the test it doesn't matter whether power is measured at the wheels or the crank as long as they consistently use the same method. Using a wheel dyno will give you a better idea if the power increase/decrease can be felt when driving as you have already included mechanical loss. Hence a 10% increase at the wheels will have a greater effect than 10% at the crank
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
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...🚀
Poor advice mate. Especially if you plan to live with a diesel engine for a number of years. Unlike petrol engines you can NOT put pure supermarket diesel in a modern common rail without it slowing down you motor over time. Fill up with the expensive stuff at least for two consecutive fills every year to clean it out. Alternatively additives are available. Also, the standard non-supermarket Diesle is also pretty good at keeping the engine clean due to additives so in the long.
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.
well I'm going easy on RPM(most of the time, sometimes I push it hard but mostly low rpm) with my Seat Ibiza SC 1.2 TDI E-ecomotive and after 46.000km it pop an check engine light, it was the EGR valve, tried to clean it with intake sprays and it vanished for a few days but it light up again and sometimes vanished ...I've cleaned second time, it was good. Started using v power and no issues at all and check engine isn't coming back - Won't go back to "regular"
