Hi I'm thinking of using this and wanted to know if anyone else uses it and can tell me the benefits of it and also of its worth it cheers

My Dad knows someone who used to work at Shell, apparently they do add cleaning agents into the fuel that do make a difference, it even makes his land rover sound nice ;)

Does it add anything to the performance cheers mate

You're more likely to notice improvements in mpg, rather than performance, in everyday driving. Use it for a bit and see if the improvements in fuel economy justify the increased price.

i used it the other day.

I saw a difference after 15 miles.

MPG shot up to 55mpg on the same bit of road i usually achieve 49 mpg on!

Does it make improvements in power? - i didn't notice any difference - but then again i was taking it easy.

Giving an increase in performance depends on how clean your engine is. If it's pretty blocked up, then the v-power will help to clear up the deposits and then will give an increase in performance. However, this is only recovering the "lost" performance, and it will not really add anything.
You could probably alternate between standard fuel and v-power and save a bit of money, as the engine will not get "clogged up" after one tank.

Also note that fuels from esso, shell, BP etc have additives in, even their "basic" fuels, so these are always a better bet than supermarket "basic" fuels. They are usually the same price too. I avoid supermarket fuels like the plague, and usually fill up with standard esso fuel, sometimes with v-power or the equivalent.

Looking at your car, the best bet for performance is either a remap (only if you've got the 1.0 ecoboost, as remaps dont do much for non-turbo cars) or weight loss (i.e, do you have a spare wheel in the boot? Consider getting rid. Only ever you in the car? Lose the rear seats, etc).

You could look at things like new exhaust etc, but tbh it'd probably be cheaper to buy a fiesta ST.

V-Power is a higher octane rating of 98, conpared too normal 95 octane, which means you get more out of the same amount of fuel

1 gallon of v-power would give for example 50miles =50mpg

1gallon of normal shell unleaded would give 45miles =45mpg

Also because the higher octane fuel gives a better cleaner burn of the fuel you get improved performance aswell as the mpg figures... Might only be around 2-3bhp possibly more maybe less but its not noticeable, the real gains are the fact its keeps your engine in tip top condition and better millage :) long winded but hope this answers your question :)

Cheers I'm getting a new exhaust soon but just wondered if I could scrape a couple of bhp from adding this as my friend told me that this is what he runs his car on I just thought that it maybe a placebo affect and that because you have better fuel the car runs smoother quicker and maybe you drive steadier so that you can notice a difference

Not trying to be a smartass or anything, but actually higher octane doesn't mean it burns cleaner or contains more power.

In fact it's the opposite way around.

Octane indicates the fuels RESISTANCE to burning.

You've probably heard about engine knocking - this is caused when the fuel self ignites before the spark plugs can make a spark. It's a common problem in high performance engines, because the compression level is usually higher, and when fuel is compressed more it becomes more combustable.

So to alleviate this problem you use fuel with a higher octane level, which will prevent it from self igniting as easily.

However, since additives are put into the fuel to raise the octane level, there's actually slightly less energy in the fuel (since the octane added doesn't burn).

98 octane therefore contains slightly less energy than 95 octane.

That however, doesn't mean you car produces less power, as it depends on the engine.

If you've got a high performance engine, it's likely 95 octane causes it to knock slightly.

And since modern engines got knock sensors, they'll adjust their ignition timing to prevent the knocking.

The side-effect of the ignition timinig adjustment is loss of power, because the engine no longer runs on an optimal schedule.

Therefore you receive higher power with 98 octane than 95 octane, even though the fuel itself contains slightly less energy.

Which engines responds well to higher octane is hard to tell, however the 1,0 ecoboost with ~125 bhp is quite powerful for its size, so it's very likely it'll perform better with 98 octane.

Personally I only run V-power in my 1,0 ecoboost 125bhp. I've not noticed a power change, but then again it's still quite new so I don't push it all that hard. I have however noticed my fuel economy improving just enough to justify the higher cost of V-power (I get roughly same price per mile, and since V-power keeps the engine clean, I choose to continue to use it)

I also changed from 95 to V-power in my old Honda Civic 1,8 140bhp - it got a slightly sharper throttle response from it.

So long story short: Try it, and see how your car responds to it :-)

It actually does help improve performance as it causes less friction in the engine...meaning less resistance against the piston and cylinder allowing it too travel down the cylinder bore on its power stroke more efficiently...which would mean more power & mpg out of the same amount of fuel

I decided to try it and cost me 55 pound whic is only about 6 pound more per tank so I'm nt tht fussed but only time will tell now thank you all for your help

Hi, I doubt very much if this fuel could give the decrease in mpg that are being claimed at all. Trouble is it is a subjective debate that has been going on for years and no-one has produced any scientific evidence apart from; 'the car feels better', 'the engine sounds better', or 'my mpg improved vastly'. None of these can be relied upon and must be taken with a pinch of salt. Thus until anyone can prove on a test bench under properly controlled conditions that it does what is claimed I will save my money thank you. I cannot see any benefit to my engine, to my mpg only a hole in my pocket...

This may be true, I do not know enough about the additives in V-power. My post was mainly to highlight what the octane number does to the fuel :-)

Also as others have mentioned, V-power contains cleansing additives, which will recover lost power IF your engine is somewhat clogged up.

New engines are naturally not clogged up (and I'd say it's safe to assume everyone with a ecoboost fiesta has a new engine), so if it is to generate extra power there are only 2 options left:

1. It prevents knocking (which is quite plausible IMHO, as the engine produces a lot of power for its size, plus it's turbo charged (which usually increases the risk of knocking))

2. V-power also contains additives that reduce friction (I've no clue about this part, so just taking wullie's word for it)

Yeah I know but I just didnt agree with that one part...no hard feelings lol! Its an additive thats coats the cylinder walls which reduces friction and meaning less resistance blah blah blah as I was saying in my last post.... But most high quality fuels have it.... But v-power nitro has around 25% more of it... It

I've used 2 tanks of 99 Vpower on mine, and i felt my 100hp ran smoother and was a bit more responsive, mpg's also went up slightly..

I reverted back to 95 for the meanwhile tho, a friend of mine had a Seat Leon Cupra, and the gains with Vpower 99 was about 20hp compared to 95, but its as stated more to do with the octane and it also reached 300hp in total...

Say in theory a mapped 125hp version might would get around 145hp, then a good exhaust and Vpower might bring it up to 150+hp..

I hope because I plan on getting mine mapped and a new exhaust :) might even swap the turbo yet
