V Power Racing

[Kris]

Anyone of you Sydney guys know which service stations sell it? Thanks

[Zuzu]

And............Still has stock..

Most have sold out and are discontinuing supply..

[WAY]

Yes, Shell has discountinued it. Also I wouldn't use it because it actually has increased ethonal mixed in there to get the higher octane. Go for something like ELF race fuel if you want to try high octane on your car. It would be interesting to see how the tune reacts to it. Given you have higher boost, I would say that it would love the extra octane!

[MikeVictor]

I started off running this fuel in my previous car and found better response with the BP 98RON fuel.

For some reason there was a laggier response from the Shell 100RON fuel, quite noticable in fact. Maybe it has to do with some of the additives perhaps?

Anyhoo, I'd recommend the BP fuel, although the Caltex Vortex 98 and Mobil 98 (which isn't available up here) are also meant to be decent fuels.

[professor]

wayne, i stopped using 100 because you (at least i think it was you) said that its bad for the engine - something to do with moisture/seals/thingummies?? did i misunderstand? what gives?

[Yep 135]

Ethanol is a cleaning agent. 100 oct as a highish amount of this. maybe prolonged use could effect the lubrication re vales and cylinders.

[WAY]

yes prof. Was me who said it's no good for the car. One off is not going to impact anything. But no good long term use. Porsche Australia recommends against using this in their cars.

[AussieRacer]

BMW's rubber seals are ethanol safe for constant use upto 10% concentrations. Porsche may not be using ethanol safe rubber or sell many cars in South America, so their recommendation is not in anyway conclusive.

V Power Racing uses 5% ethanol - but is being discontinued.

ELF fuel is a little expensive for everyday use at $5+ per litre.....

[Kris]

Thanks for the info AR, $5+ per litre hehe - expensive, you are not wrong!

I wouldn't mind trying it in the car on the dyno...It's a pity Shell 100RON is no more!

[takahashi]

It is not a pity at all. They used to be good but the last fill I had was very bad. Now I use BP ultimate on any car and it is much better from what I gather from a lot of people in different makes of cars.

[Wraith]

As a point of reference, I tried the 100oct. shell fuel on one of my turbo cars last year - 2 tank fulls back to back and found ZERO beneifit or increase of performance compared to their 98 optimax (V-power as they now call it) and in fact, it returned less range - my driving style was unaltered !!!

Also as a matter of comparison, this particular car of mine also seems to respond better and give more power with V-power 98 than it does with BP Ultimate, although the BP Ultimate seems to make the engine sound/run smoother...

My conclusion was that for the extra money it costs (well was it used to coast as now they're phasing it out) it's not worth it !

I would only use it, if your car has been specifically tuned to run on 100octane, then there would be an obvious advantage and justify the expense :smile:

[BMWDave]

while we're on the topic of fuel, do you guys mainly use 98 or happy to fill up with premium?

[Zuzu]

Nothing less than 98...BP Ultimate..

I did try a tank of Shell V racing a few tanks back. Didnt make any difference IMO.

[WAY]

Always 98 octane. Although I have been mainly using Shell due to it's availability to me. I do agree that BP is a better fuel though!

[Kris]

I use BP 98

[professor]

just curious whether there have there been any definitive independent tests on fuel quality across the main stations in australia. has anyone read any reports on this?

[Kris]

I have, they rated BP 98 as the best and contained far less benzine then most other fuels meaning it was better and cleaner then the environment. I cant remember where I read it

[qship]

I've used BP ultimate for ages but recently my Lib GT took to running poorly. Subaru's first question was "Are you using BP?" I said yes and they suggested I change as the current brew in Melbourne is a "winter blend" (no I don't know what that means) and is causing some issues. Changed to Mobil and sure enough the problem went away. A number of subies appear to have had the same problem. BP have admitted to the "winter blend" but apparently will not elaborate on what this means.

To be fair the 135 has not had any adverse reaction to BP althoough the idle aint smooth.

There have been numerous - if you google, you should find plenty to read and food for thought, problem is it all depends on the batch and how clean it is, how long its been sitting there etc. etc. and then they all vary from Country to Country - it's damn hard to find a consistant batch of any type of fuel, once 'you think' you've found the ideal one or type for your car...

Also be wary of tests/reports that plug or push their own products...

[imported_Dodgy]

Swap between BP and Shell, depending on timing and vouchers. (Wife loves to shop at Leo's unfortunately). Always 98.

Haven't paid attention to differences between the fills, but might do so due to the "Winter" factor.

[AussieRacer]

Dodgy, sounds like we have the same local BP servo :smile:
