Dose it really make a difference to the majority of cars? With the current price of petrol it hard to see why people buy it.
BMW Z4 2.2i, I got higher MPG with V-Power and other higher octane stuff. This made the cost per mile the same or sometimes lower than using 'normal' fuel.Calculated tankfull to tankfull on an app.
My other car was an M3, so did not try any 'normal' stuff in it.

My dad's car has a knock light. It flashes all the time on any 97 RON petrol (nevermind 95), it doesn't with 99. So to answer your questions:- Yes
- It's cheap compared to a new engine/octane booster

Depends if your car has an ECU which can make use of the higher grade of fuel, most modern peformance cars can. If it can then you'll usually see an increase in power as well as slightly improved mpg. If it can't, then it's a waste of money. What car were you thinking on using it in?
There is a very noticeable difference between super and V-Power in my Evo. Can't tell any difference between that and Tesco though.
Interestingly my Diesel X-Trail was getting a bit smoky under acceleration so on a long trip down south I ran two tank fulls of the V-Power diesel through it and mpg was noticeably better and the smoke has dramatically reduced.

I see that you have been on here for at least 18 months. Have you really missed all the monthly V-Power bun-fight threads, so need to start another?

Try it, it might run smoother and see slightly better mpg. Probably enough to make the pence/mile cost the same at any rate. vPower has additives to clean the injectors, so it's worth running.That said the higher octane allows you to run a more aggressive timing and tune. Most notable on turbo/supercharged cars, as it lets them run with less likelihood of pre-detonation. But even n/a motors when setup to make use of the fuel will run better/make more power.
Don't go using it thinking it'll give you a nitrous oxide boost in power though (like some people seem to

erm ok. Not being funny but why not try starting with Google (maybe Wiki) and read up on what it is and what it does first.
Do know what it is and dose, have also seen the projams where it's has been tested just thought it would be interesting to find out of people how they have found it .300bhp/ton said:

I get paid on Friday so might give it half a tank and see if there's a difference That said the higher octane allows you to run a more aggressive timing and tune.

Sorry to hijack the thread, but would it be worth putting it in a 1997 528i? I normally use the normal stuff at Tesco, sometimes their super unleaded if I can't be bothered to wait, and not really noticed a difference.
The answers the same as all the above really.1. Read up on what higher octane fuels do and why
2. Read up on specific brands and see what they offer
3. Read up on your car and find out why it will/won't make a difference
4. Just try it, but be realistic about the results and it's capabilities, it won't make a 528i suddenly as fast as an M5, nor will it start doing 60mpg
How big a dose does one intend to use?
My Impreza has a sticker in the fuel filler cap stating minimum 97Ron.
Always use V-Power, mostly as there are 2 Shell stations near me. Switching to BP Ultimate on occasion out of necessity has seen the engine light come on for a few minutes, not sure why.

In reality I doubt it'll cost you anything more when you work out your cost pence/mile. But I also suspect you won't notice a huge difference in how it runs either.Also I'd say you'd probably want to run two full tanks of it through, and you're more likely to notice the change when you then switch back to 95 RON, rather than when going to superunleaded.

Your cars engine is fitted with a 'knock' or 'ping' sensor, so the ecu should be able to advance the ignition enough in order to benefit from the higher octane rating that v power has.Try a tank or 2.
