V-Power & Regular Unleaded Comparison

Liquidfox · 10 Jan 2013 at 21:19

I seem to remember a while back a story with accompanying images floating around showing a car (A V8 Audi R8 if I recall), that had been modified so that one bank of cylinders ran on V-Power and the other on 95RON. There was one key image that showed the difference in condition after been ran for a decent period of time.

I've tried for the life of me to find it but I'm having no luck. Almighty OcUK Motors, please find it for me!

Peasant fuel:

V-Power:

Yep, much better condition.

Since using vpower that's never happened to me so I guess it proves the point.

Im retweaking my mk4 at the minute to make it more economical, next step is see if it can safely use 95Ron . Currently no pre ignition on 98 or 99 Ron, ill report back after the next tank to see what 95 Ron did

I'm hoping I didn't dream this one up

I run one of my cars exclusively on V-Power and the other on regular (usually Shell), but neither have caught fire and/or blown up. Where do I stand? :confused:

BP have an Audi A8 with 4 cylinders of each fuel

Doesn't make the blindest bit of difference in my car.

Any information?

Mine seems to prefer it, idles better and revs a little more freely. Haven't noticed an mpg difference although I have only ever used two tanks of normal.

I have to run V-Power on mine if I want to use the current tune, the drop from 99 to 95 RON would mean I have to change my map (map selection with the cruise control buttons) from the 18psi to 14.5psi which would mean around stock power so I would drop 100hp.

My car much prefers it, Mainly because its quite high ish compression and also because the book says specifically run it on 97ron
doesnt even mention 95.
Although it runs ok on 95 too just a bit lumpy and it doesnt sound as awesome

Not tried V power in my eco wagon yet. However I have averaged around 4 MPG higher using Shell 95 over Esso 95 but I'm gonna run a few tanks just to make sure it isn't just me driving more economically!

Would like to try V power one time.

Always run on tesco momentum99, better mpg/more out of a tank, cleaner smoother running engine and slightly more responsive. Peasent fuel is a false economy

BP Ultimate Audi A8. Its pretty old now but interesting. Engine is the the port injection V8.

Given that V-Power really only makes a difference if the engine management system can advance the ignition, it's hard to see how that test could either work, or prove anything? If the ignition doesn't change, you're wasting your time running V-Power surely?

On the "more power" side of things, yes it would be a waste. But you should still get the "engine cleaning" and "more MGPEEZ" benefits...

I have to run 97 or higher in the S2000. It will "run" on 95 but my god is it horrible. It vibrates and makes much less power.
The Jaaaaaaag gets normal shopping cart fuel. It doesn't seem to make a blind bit of difference to it 97, 99 or 95.

What test?

You must mean another one unless you are confusing octane number with cleaning performance. Octane has nothing to do with the test I linked to and it certainly doesn't need the ECU to tell the fuel to clean the engine.

My oil burning 4007 runs smoother on BP Ultimate diesel. And I most definitely get a few more mpg out of it across the board. I'm paranoid about using supermarket fuel in it since I had a bit of a scare recently when it went into limp home mode. Feared the worst thinking it could be DPF/FAP related but it turned out to be a dodgy fuel filter.

My superbike has always been run on a straight diet of either V-Power or Ultimate though.
