I'm sure it says somewhere in the manual that running on super will improve MPG and bhp. The Cooper S has a knock sensor so can take advantage of higher ron fuels.

I'm running on a tank of Shell 95 at the moment after a few tanks of Tesco 99 and Shell v-power. It certainly sems to pop less on the lower grade stuff and power wise it's maybe a tad 'flatter'...

Yea it does say in the manual about maybe 97 ron fuel is advised to be used. you will gain some improve,ent if you have never used it before. it will seem sharper on the throttle and maybe a little power increase and will run better over time.

Which pic?the signature one? Thats us all on The Great North MINI run me and Andy organised last year

I've just switched to Shell V Power from ordinary 95 octane Shell - now it's on the second tank, I seem to have much improved consumption (which I can't attribute to changes in weather, or driving conditions).

My original plan was just to pop the occasional tank in, to help keep the engine clean, but the engine seems smoother, and consumption has improved - maybe another 70-80km from a tankful, so I'm going to keep going.

I used v-power when i first got my MCS for about 5 tanks worth and now that ive switch for the last few months I have noticed more "pops" when I come off the gas.

A slightly different question for you all, Do you think that fuel additives actually work? I think Reddex is a main player. Has anybody really used these much and if so do you recommend any?

Tesco super unleaded is 99 ron so a bit cheaper than v-power and in my opinon just as good if not better. I try not to use anything else.

I used Bp standard up unill sept last year & found that best but after having to use tesco as only petrol station arond were i was - i tried the super & what a differnce. To be honest i didnt believe in it but you defo get an improved mpg - i have tested it. I have tried the other supers & always gone back to tesco.
For some reason this suits the mcs

I perosnally dont use anything since then

When I first got my car I was using 95 but then moved to higher RON fuels now using Vpower as I get air miles..... For the sake of an extra £ or two per tank its a no brainer for me...

Hi
to be fair im going to try it because of everyones feed back sound v good and also
i shop at tesco and if i spend over £50 you get 5p of a litre which will bring the price back to standard unleaded.

[ScottyBoy]

Theres your answer its always great when you get 5p off every litre

I have never bothered; I have no faith whatsoever in additives. I always thought it was more of a yank thing.

Personally, I reckon that good brand fuel from a high turnover petrol station (Shell, BP whatever), combined with regular and frequent oil services, plus the odd "Italian tune-up" (to keep the pipes clean) is enough to keep your engine sweet.

Interesting discussion this. My old Rado VR6 used to pop and crackle a good bit more on vpower but i've only run my mcs on regular 95 so far.

The extra mpg would make it worthwhile but would it really give an extra 10-15% to balance out the cost?
