Anyone noticed any performance hits by moving from Shell VPower to BP Ultimate?
Also, the car is Rtec Stage 1 mapped on vPower, this shouldn't affect anything should it?
Reason I ask is, we've just moved to deepest rural Hampshire and there hundreds of BP garages all over the place which would save me having to drive round the houses to get to the nearest Shell.
-
Iirc BP Ultimate is only 97RON (is round my way) and shell is 99 Ron. I use Tesco momentum as that's 99Ron
-
Isn't ultimate 97 and v power 99...
-
Think so, so is it ok or a bad idea?
-
Tesco Momentum here too, used to use Optimax / vPower but since Tesco opened here I can't tell the difference between the two... Only in the cost.
Never liked BP ultimate on tuned cars.
-
Theres more to fuel than just the RON.
V-Power is better in terms of resistance to knock (when logging CFs)
-
Your car is mapped to higher octane so the ECU will be holding back the power (timing pull).
Long term that won't be good for your car so aim to run on 99RON wherever you can
-
Why not fire an email to R-Tech and ask them if they think Tesco Momentum will suffice? Or runs some logs with VCDS to check for yourself.
-
Ok cheers guys will do, sounds like better sticking to vpower just in case
-
Mad isn't it, the 2006 Gallardo can pull ~500 brake on 95 RON.
Never had an issue with momentum, but would love to see if a tuner thinks otherwise.

Momentum is just as good as V-Power, some tuners actually prefer it. I like it coz its cheaper :wink:
-
My car is mapped by Rtech and was mapped on Vpower. Works fuel account is with BP… basically free fuel on BP or fuel the car myself on VPower. There is a difference between the two fuels… Vpower is better, performs better on Economy and also pulls harder at the top, feels crisper. BP feels a little flat after using Vpower.
3xBP and 3xVpower is how i do it.

I filled up today using Tesco Momentum 99 - so far I have found that the mpg I get on the same journey is better with M99 than with Shell Nitro.
Will test 95 RON on the next tank I think.
-
a tuner recommended me to stay on v power/nitro for the better cleaning agents
-
Cool cheers all,
Sounds like its Shell continuing to get my Fun Tokens at the pump :happy2:
-
Just received a voucher from Shell for £21.50 worth of fuel from using my loyalty card......result! :happy2:
-
Sick one! I generally use Shell nowadays... either that or BP.. now I'm filling up with diesel it makes little difference :P

Specific output is only just over 100bhp/litre on a Gallardo that is naturally aspirated.
Specific output on a tuned K03 can be north of 130bhp/ton, on a K04 that can be well over 200bhp/ton.
Always use at least the recommended ron for the tune. :happy2:
-
What's the Golf's best N/A effort? The Mk5 R32 = 79bhp per litre.
The 6.0 W12 concept is off limits. :party:
I'd still take a Gallardo if anyone wants to swap. :evilgrin:
-
What about sainsburrys super unleaded ? Should I be using that or not ?

I tried it for a bit. It pales in comparison with Tesco / V power :smiley:
-
I've been using it the past few months, was using shell buts it's about 5 mile away where as sainsburrys is less than 1 mile away. Haven't really noticed any difference really, should I be using additives to the fuel as well such as redex etc
-
Redex and other additives can wash down the bore and contaminate the oil so should only be used just before a service.
BG44k (Google it) is much better than Redex though :happy2:
-
Okay thanks.
