My Astra runs much better on V-Power fuel it picks up better and feels smoother through the revs. My last couple of tanks were Tesco 99 and it does not feel as lively and a bit lumpy at idle.

Im surprised by this, ive never noticed any difference between how either the 350z or the M5 feels on Momentum 99 and V-Power...

My focus ST gets better mpg with v power it seems but not noticed performance improvement vs Shell regular

Found the same with my 225.

The 6.0 V8 Monaro can get a huge difference when running V-Power, 27.1mpg compared to 22mpg on a long motorway journey at 70 on cruise control.

Maybe it’s more noticeable in smaller turbo charged engines ?

I’m currently running mine to empty before I refill with V-Power again.

I've always thought the same, but I'm starting to wonder if it's just placebo now... I definitely do get slightly better mpg on V-Power though.

With Tesco 99 mine feels a bit hesitant and not as smooth when revved slowly through the revs. The idle is slightly lumpy too. I don’t get this with V-Power. My GTC with the same engine was the same too.

It’s not a huge difference but certainly noticeable enough for me to prefer using V-Power when possible.

so in Cambridge 1.47 V-Power, 1.35 Momentum , ~1.30 normal
Subsequently read elswhere, if you just want high Octane then Momentum, or if you want better detergent package V-Power ... so a 50:50 mix

Just got 65mpg from a 50mile trip in a new Nissan Micra 0.9t on normal supermarket petrol, maybe i'll break the 70mpg mark with premium stuff

theone8181 · 30 Aug 2018 at 18:30

I filled up tonight, normal shell was 134, premium was 144. So 10p difference over a 50 litre fill. An extra fiver however the increased mpg is worth it, plus I don't really care about the cost of it anymore. I spend roughly 3 grand a year on fuel, saving less than 10% is nothing.

Nasher · 30 Aug 2018 at 19:44

Filled up with Momentum 99 earlier and it was 134.9

Strange logic. 10% of a lot, is a lot.

as calculated ... previous page ... she's worth it

having chosen momentum, as commented by Moogleys, does nor run as well as my recollection of last years V-Power fill.

I still need to experiment with the 3rd way Red Line SI-1
but need to know how to effectively mix it ... do we know what volume of detergent(non-inflammables) is in v-power ?

you mean your commute is in london and it would be an extra mile ?

I don't think I get any gains in MPG but they claim that premium fuels are cleaner and easier on the engine so I take their word for it. Fool on me maybe but at least I like to think it's working. Maybe a couple more horsepower too but it's hard to feel any difference.

Anyone got any data on premium diesel?

Wow petrol is expensive where you are, I just filled up and momentum is £1.269/L!

chroniclard · 31 Aug 2018 at 14:10

Momentum is £1.429 at local BP. :mad:

Normal is £1.329!

PaulCa · 31 Aug 2018 at 14:18

The GT86 states "98 RON ONLY" in the fuel cap. However running it on supermarket 95 RON petrol is fine, but the ignition has to be retarded a little to prevent knocking, thus reducing power by a pretty much un-noticable amount. You might notice improved MPG with 98RON, maybe not.

I exclusively use BP Ultimate 97 as it's available readily where as the other premium fuels are not.

I would be annoyed at BP to be honest selling tesco fuel
