oh and by the way i make my own brake disks from lumps of wood and use cotton wool for brake pads They work real good.

 

More marketing clap trap.

If the car is tuned to run on 95Ron, reliabilty is not affected whatsoever.

 

It must be true though shell say so !!! And i can really feel with my calibrated senses the half of a horse power extra it gives. God i'm getting bitchy

 

Interesting article for all to read and get back to the point in hand!

Thorney Motorsport Fuel Test Results

Sounds very thorough.

Still can't understand why the F owner puts in 95 & says it's fine?????

As we have said, it's NOT about ££££, cos if you can aford to buy 1 of these, you must have a few££??

Damn you Jason, you got there first, I was gonna post about the 5th Gear review !!

Incidentally, they founds it made virtually no difference on a supermini they tried, due to the more basic ECU.

Anyway, I agree. They found 14 bhp difference on an newage Sti between an 95RON and V Power. Actually one of the cheaper mods available !

My friend has just bought a Ferrari 360 (pics once it brightens up) and will only use V power in the car, as in the owners manual it states to use Shell fuel.

It also say use Shell oil on the Oil filler ...But Ferrari also used to reccomend Agip fuel and oil in other countries

Like BMWs say use Castrol

Selenia for Fiat/Alfa

And Renault says to use ELF

Porsche said to use Shell...then swapped to Mobil One.

Make of that what you will.

 

And these differences would be even greater if the car is specifically mapped for V-Power. Running V-Power and methanol and having the car mapped for this combo is currently allowing me to make an extra 50 (yes - fifty!) bhp compared to running it on plain 95RON

 

Sounds good. Is that on the std VF35 Lunar ?

 

I know people that run the 2ltr clio`s on 95Ron. But looking in the wifes old 1.2 clio handbook it clearly stated the 2ltr's should be run on 98ron, but it was ok to run them on 95 ron occasionally if you drove accordingly. It says use super unleaded on the fuel filler of my scoob. So it gets super unleaded. The couple of times I have had to run it on normal 95ron, It seems a little bit more sluggish, and only manages around 245 - 250 miles before the light comes on. On super I get between 280 - 290 miles before the light comes on. Done a quick check of the maths. And it is just fractionally cheaper to run it on super, as I get an extra 2 days of commuting between refills. But if your doing lots of town driving the differance is going to be a lot less.

Hi guys not 100% on all this my self, but I run my 2000 with decat on Tesco 99 most the time, one day tho I was running low(on the light) and all I could get was Sainsburys 95 ron, my car really didn't like it, didn't feel as sharp on acceleration and whilst driving home on the M11 there was a noticeable difference most the way, some of it could have been physiological I guess. I try to stick to 99 at the mo but as the price of fuel is ever increasing I may try running on Tesco 95 for a while.

 

What the hell do you do for a living!!!

Must be the best 70mile round trip tho?! All those miserable commuters in their 'average' cars seeing you with a big grin across your face!

Back to the debate at hand. I have a Jap import WRX, and HAVE to run the car on high octane fuel, 99RON fuel is standard in Japan!! Thats why Jap cars all kick ***!!

 

Bp have introduced Ultimate 102RON fuel. Should we all convert to that??! I bet its £1.50/litre! At least!!

 

Bargain

If you can afford the car...why not?

 

On a slight tangent, I've been using the V Power Diesel in my Fabia vRS and it seems to give a bit of extra punch but also increases overall MPG by about 2-3 so costs about the same. Anyone know if there really is much difference? It could all be in my mind!

 

My impreza even tells me to only run it on Super unleaded on the fuel cap...wouldnt dare put 95ron in

 

Doesn't it also say "Gasoline"?...i.e not petrol

Its worth bearing in mind that even with a UK (EU model) car, that "Super Unleaded" branded fuel can actually be 95RON in various countries (or was at the time of production). And thus that sticker is used as such for a basic guide, but doesn't accurately reflect what fuel the car can actually run on.

The most relaible source of information is the actual RON value. Not the branding. The acceptable RON values for your car are given on the back cover of your owners manual.

So, depending on the model year and market origin (EU or JDM) it may not be as daring as you may think.

 

Surely this is more to do with where your car is from. As someone pointed out 99RON is standard in japan so JDM market cars are designed to run on this. UK cars are designed to run on the fuel available i.e 95RON min. Putting 95RON in a UK car is no problem. Putting 95RON in a JDM car (which isn't mapped for it) is damaging to the engine, it causes knocking. Hence the reason I use V-Power, unless i really have to use something else. Incidently where the hell are the Shell garages in the Lake District?

 

I'll explain it to you - guy drives a Ferrari so probably has a good few quid. I doubt he is a car enthusiast (anarok) in the true sense of the word as most on SN are, he owns the Ferrari because its a "posh" car to own and he can afford to own it.

He isn't arsed about modifications, doing his own servicing, cleaning it, or anything else other than jumping in and driving the thing and most of the time he will pootle about in it.

He won't care that V-Power "may" give him a few extra horses, as only true anoraks will believe that you can feel a 1-2% increase in BHP

He wont care that 95RON may be slightly worse for his engine (if indeed it is) in the long run that 98RON as the car and engine will be under warranty if its newish.

He probably has a full life outside of messing with cars so really doesn't give a crap about slight BHP gains from using some fuel, 95 is perfectly OK to use on most cars.

My Pug is specifically mapped for 98 Optimax but I wouldn't worry about the odd 95 fill up if I had to - I tend to use SUL where available as fuel costs don't bother me for the small miles I do.

BUT, it is all nonsense in reality.

 

Agree with much of the post, although (pedant hat on), 14bhp is more like 5% increase on an STi. Can you feel it ? Maybe. But surely it's worthwhile for 5% extra, even if it just makes us anoraks all a glow inside.

(Differnce is far greater for my car as it's mapped for VPower).

 

No Andy - I'm running an MD321H. Don't know what extra you could get running this same combo on a VF35, but I think it would be substantial. AndyF could be the person to consult on this one
Cheers, Andrew

 

Yes, seemed to recall you saying that. Sounds excellent. Were engine mods required too ?

 

Penrith is nearby as Is Kendal. Further afield you have Carlisle to the north (2) and Ulverston and Barrow to the south. Not great coverage I'm afraid
