Worth using V-Power ???

27th September 2011, 21:20

The guy ive just bought my VTR of said he always used V-Power instead of standard fuel ?
I thought it was just for top end car's and not really needed on saxo's etc....
Anyone offer up an opnion ?

Just use whichever fuel you want and see if you notice any difference. More than likely wont be able to tell, so just use normal fuel.

27th September 2011, 22:02

It's a higher octane which means it burns better, more efficiently!! So u need less for the same bang so can give betta mpg when driving sensibly or as it burns betta on higher tuned cars and turbo vehicles can give betta performance but not that u wld notice!!

Its noticeable on cars that actually benifit more so from it! Alot of saxo's that are cammed and mapped using vpower or whatever wont idle on normal octane fuel!

On a standard car you wont really be able to tell the difference.

Most people with any sense will map the car on 95 ron.

i managed a whole 5 miles extra on super but cost another 7 quid to fill up .also didnt notice a great deal of difference

27th September 2011, 23:41

pointless unless its mapped for the higher ron.

asda fuel is the way forward, 170 miles on track from a full tank with a 5l jerry can

27th September 2011, 23:49

pointless on a sax as the engines dont have variable valve timing and they arnt exactly supercars lol

28th September 2011, 09:25

you dont need VVT to benefit from V-power. Its the ignition timing that gets altered by the ecu for different ron fuels. Its a VTR though so just run it on the standard fuel.

28th September 2011, 09:46

If its not mapped for 98 ron then no, waste of money imo..

All these people who blab on about how their cars faster, smoother and all the rest of it well..

28th September 2011, 12:50

the ecu can advance/retard the timing, and will vary that until the knock sensor detects knock (surprisingly). With higher octane fuel, itll run more advance, increasing efficiency (and torque to some extent).

Will it be enough to feel on a 1.6? Very doubtful.

28th September 2011, 13:01

Cheers for all the ryplys. It's what I thought really. Might do a tank on each next time it's empty and see if I notice a difference. Also I read on another forum ( different car) that v-power can make your car more vocal I.e pops etc as it's slightly more explosive. Another Internet myth ?

Never actually checked, but how much more does it actually cost per litre compared to normal fuel?

Oh and...
answers my question aswell.

28th September 2011, 13:19

Doing one tank on each won't be enough to compare mileage per tank. You need to do like 3/4 tanks and note how miles you did on each tank, get an average and then do the same again on the other fuel. That way u can then really compare the difference.

I am aiming to do this and see what happens.

I run at the 182 on Tescos 99 as inside the flap it says its recommended, probably due to the standard map, plus I've heard people having engine management lights popping up on the dash when running 95 -might be bullshit but better safe than sorry for the small price difference. The saxo just gets the cheapest 95 I can find.

Oh and... 5th Gear - High Octane Fuels - YouTube

answers my question aswell.

Id forgotten about the ch5 video when i was doing some reading into higher ron fuels and the ecu adjusting the ignition.

General consensus was high compression/turbo engines got the best results (as shown in the video).

Figures were around 7-10% from some journals I read. Ill be hopefully testing the idea soon on the same rollers mine was mapped on 95 ron on, ambient temps will still be a variable though sadly.

Ive run my 172 on 95 ron loads and never had the light... I do tend to run it on 98 ron every now and again though. With petrol prices how they are now Ive been ignoring it a bit more

I have a tescos petrol station directly behind my work so its more convenience for me! I think that management light might be other issues on the car that people have had but if its says 98 on the cap i'm going to stick to it as they wouldnt waste the money putting it there otherwise.

earlier for me it was 8p a liter tbh when you fill up a tank it's not that much more

I run the m3 on Optimax nothing less

S50's are mapped to run on 98ron so anything less and they start throwing toys out the pram..

28th September 2011, 16:02

All engines are different, cant see a saxo being noticably different on the "super fuels"

28th September 2011, 16:05

I've ran the ST on

Shell V-Power
Shell Regular
BP Ultimate
BP Regular
Total Excellium
Total Regular
Tesco Momentum 99

The best by far are V-Power and Ultimate (the inside of the petrol cap says "Ford recommends BP"), Tesco might be a higher octane but theres no escaping the fact its shit supermarket fuel.

Think i read a report somewhere on the internet that said BP and Shell filter their fuels 15 - 18 times where supermarkets (like Tesco) only filter 5 - 7 times

By that, even if Tesco are offering 99RON, the shit in the fuel will bring the performance down to that of the cleaner Shell and BP fuels

These are MY opinions based on MY experiences, different cars react to different fuels with different setups, ive just noticed that the "super" fuels felt alot better to run

Yeah think this is what Mandyslovers getting at, i know Citroen always recommended TOTAL, but when i ran my saxo on regular then Excellium, all it did was clean my engine out, like Redex would

Had some fierce over revving issues, after several full tanks of super they went away, never really noticed any performance gains though

Easy to see why they'd recommend Total as its a french company. Probably a buisiness marketing thing.

Might be worth a read ^

higher octane fuels burn better an more efficiently, also cleaner, so in effect whether your car will notice a gain or not, the engine will be happier on higher octane

tesco 99 is proven to be a good fuel, although i cant say the same for alot of other supermarket fuels.. my car for example will hardly run on sainsburys

gibbo your wrong, even on a car that isnt mapped for higher octane, if you have the right car/engine..eg boosted or highly modifed.. you SHOULD notice a difference by running it, youll see more if its mapped for it though..ecus set themselves to fuel as said by regulating the ignition timing.

on non boosted and mildy... to non-modified cars the difference noticed will be un-noticeable

fuels that are reccomended by manufacturers are normally because A) either company has mapped their car on that fuel, which means its going to run better and more efficiently, or B) the manufacturer is receiving money for ppl being coaxed into using a certain fuel

if going to get a car mapped, its always best to get mapped on a full tank of fuel you will use all the time, and one that can be easily sourced, also reccomended if the car is used alot on road, to get it mapped on lower octane and run on higher octane..then if you ever get caught short and theres no garage to supply your/higher octane fuel... you can put normally fuel in without risking causing damage to your engine

Re the tesco v thorny thing.

Thorney is sponsored by them so I'd take that with a pinch of salt.

28th September 2011, 18:06

I recently filled up with texaco's posh petrol as the pump was broken for std fuel and i couldnt be arsed to move the car. I ususally get around 29-32 mpg on 95RON, on the 97 stuff i got 39mpg. Didnt notice a difference in the way the car drove mind.

The car was mapped on esso's 95 octane stuff which i usually use.

I used super 97 for a good few months as the Shell garage was far away, without any probs

28th September 2011, 23:18

Mine just says some random japanese stuff that I cant read. Guess it means high octane. Ive never run it on anything other than Vpower, Ultimate and Tesco 99 or whatever it is. Dont think these compare to Japans rocket fuel still so I wouldnt try 95 sewage.

28th September 2011, 23:23

always best to get imports remapped as soon as you can tbf

thats why all the p1 scoobys normally blew up, ppl run them on 95 ron, and the detonate for a long time untill they eventually get the death rattle and pop

28th September 2011, 23:58

Be fine, ive got alot of petrol station near me

10th January 2012, 16:35

Just to revive an old thread (sorry) a B18 civic produces an extra 12bhp on Vpower. No other mods. 95ron to 99ron is 12bhp!

for an extra few quids that Vpower costs thats gotta be best bang per buck going aint it?

If you guys like I can can compare my VTR on all 3 fuels 95ron 97 and 99.

Is that B18 mapped for 95 or 99?

My mate had no choice but to run his JDM EP3 on 95 and said it was lumpy and almost stalling. Heard some horror stories from people running UK sewage in JDM mapped cars

Standard ECU. no map.

The K20 ep3 of my mates also saw 11 or 12 bhp gain under same conditions. Again no remap.

Not bad, not many people can notice the difference though, cant remember if it was UKDM or JDM members posting though. That sort of gain is good figures then for us with JDM models.

Compression ratio is quite high on the VTS so it's likely to perform 'best' on the super fuels. I've been running the S on V-power for 3 years - could be hundreds I've wasted but I'm not fussed at the end of the day. It certainly runs smoother than most other VTS's I've been in.

Thats what its all about at the end of the day Barry. Its what you want to do.

Like me, Super unleaded at least but Vpower preference.

That one minute You need your car performing its best coz some repmobile is on ya case, well, ya better have a tank of the good stuff on ya side.
