Guest, 🚨New Stock alert: Premium CUPRA valve caps now available in the store 👉 Order now from the merchandise store
also i tried the tesco stuff for 1 tank (when the prices were around 97p) i was ready to run out of fuel, and tbh i was very suprised by it..very smooth. i would use it now if not for the fact it costs more than v power....
shaun from AmD recommends tesco 99 as the best fuel for our cars

There is a real but relatively slight effect- read the manual as to power output which does stipulate that the quoted figures do depend upon the fuel used."98 or 95 (with slight power loss)" P271 in my 07 manual.
There is no doubt that premium branded fuels do have the best additive mix for clean combustion and avoidance of pump and fuel system fouling- but the octane rating does not decide that. Supermarket and budget brand fuels may be as good depending what their buyers have sourced- they can and do use the spot market. So you may get a fine quality product from a cheap pump if that is what they have found at the right wholesale price. The only ropey fuel problem in recent years came from supermarkets- Morrisons locally- and fouled up lots of lamda sensors.
So, there is no need for "willy waving" posts or "my grand pa always swore by lamp oil and turps" posts The manufacturers reccomend 98 for higher output but make clear that 95 will do fine.

It can only make a real difference if the cars ecu is set up to take advantage of higher octane properties. Petrol flap should say what octane is adviseable. It's take the car's ecu thousands of miles to calibrate it automatically.
Obviously remaps alter the ecu so you can have them set up to run on various fuel types.
Example big S4 twin turbo's can run at 440bhp standard fuel and 500+ with race fuel.
Its all aout pairing the ecu with the fuel or there will be next to no performance benefit.

Turbos were on cars before the 70's mate. Go check out youtube.
I have owned many cars with turbos both petrol and diesel powered.
In fact I did a turbo conversion on an F reg mini 1000
Also one of my more memorable turbo cars was a Mitsubishi Gallant 2.0 Turbo on a Y reg.
There was exactly the same sort of debate back in the day about 2 star and 4 star and then unledded.
Exactly, how some peeps can detect a difference with just a tenners worth just adds to the plasebo effect reasoning.
i only said 1970 cos you said you have been driving over 20 odd years......dont care what anyone says, in my car it didnt wanna go anywhere on that fuel..it had no guts, was lumpy, and boost was generally weaker....my car isnt setup for 98 either, but when i go to stage 2 i may get it setup just for 98.....
the 10 pound fuel is getting burned isnt it....got nothing to do with how the car thinks it is 95 or 98.....if i put my foot down and it feels crap then the fuel is crap....its common sense
ok nath answer this....if there is no difference whatsoever...then the ECU has nothing to recalibrate has it lol
My current Leon is standard and has not been on a dyno, I have given Vpower a go on my old mk3 Ibiza Cupra that was remapped and had intake and exhaust mods. I have used the Vpower diesel in a 1.9 CDTI Astra SRI and a 1.7 CDTI Astra Club too.
I'm not skint by any means and I'm not tight but I just don't see or feel a difference.
I didn't ever say that there was no actual difference (see post 10) I reckon that there may be about a 2BHP gain from using it. I just think that if you can detect 2BHP extra on even a 100BHP car you should be on Britian's got tallent.
read my posts mate, you won't catch me out
Maybe you should go on that program and drive cars on a dyno and then guess the BHP? I reckon you'd enjoy the lime light

stick a £10 of green Avgas in and then see what difference the Octane makes
seriously though it is personal choice thanks to the free world we live in but explaining to many a friend or foe i always suggest run a couple of tanks at least of the top stuff and then go back to your normal fuel
after that if you reckon it's worth the extra £5 a tank then you will pay it if you don't then you won't, not rocket science, flying a man to the moon however . . . .

Couldnt notice any difference on my standard motor either.
On the dyno the car made 11hp less when I didnt have it filled with vpower with just the map
Yes Flapper,this is what I have done and my findings are that for me it's not worth it.
I'm just adding my opinions to a public forum and passing some time, after all the OP did ask and I do own the car the OP was refering too

matey...im having a deja vu moment here...its not about the power!!!my point was about the smoothness and lumpyness..wow dude a bit touchy arent ya...
dude, forget the power, drivabiity is better on the good stuff
power can be different but it needs to be in a lot higher scale of motor to notice real differences circa 1200/1500bhp
drivability is pretty much the reason i personally use it plus the mk2 gets stroppy with me if i dont
wow dude a bit touchy arent ya...
Not at all, it will take way more than this to rattle me
Drivability eh? this is getting more and more laim. Does the ECU need to adapt to the extra octane to produce more power or not?
You say that with the regular stuff it feels crap and didn't want to go anywhere but now you've tamed it down to "drivability". PPPFFFFTTTTT
Your placebo needs a vpower shot methinks

Iv got a question, i don't have any experience with petrol or performance fuel, but would putting Millers additive in with standard supermarket diesel give the same results as using just vpower? I know that on the bottle it states it can increase the diesel cetane by up to 4 numbers, is cetane in diesel similar to the octane in petrol?
Is it just different octane and cetane numbers between the standard and performance fuels?
Ok maybe that was more than just one question
