im using momentum as its easiest to get hold of and thats standard 5p more a litre

Is momentum the tesco premium fuel? I will prob use v power cause the shell garage is right by work.

Momentum is tesco. I dont have any shell garages around me so v power is scarce

BP Ultimate is double Nectar Points so if you're gonna go higher fuel, make the most of the offers

Momentum is good sh!t I use it in the focus it bloody loves it

Most of the garages that are close to me are shell garages. I normally get £10 off fuel every quarter from she using there loyalty card, you get double points for v power so should get more money back

A dickhead at my work put BP Ultimate diesel in his van to get the double nectar points, £1.59 a litre.......!!

There really is no point putting 99ron in a ecoboost engine unless you have it mapped

hear a linkage to high octane's.

Enlightening videos, thanks for the links. Basically for me, I'll stick with the standard 95 ron petrol. I'm getting 44mpg, and only put my foot down hard for overtaking. Even on fun runs that extra possible 5 hp shown on the golf GTI wouldn't benefit me enough to pay the extra.

At the very end of the day unless your car is specifically mapped to use higher ron fuel, it is doing absolutely nothing to your engine apart from potentially cleaning it out due to the extra detergents in it.

Most cars 2000 on have a 'knock' sensor which adjusts the timing depending on which fuel you put in and when it detonates - these can compensate for higher RON fuel, however, it won't improve performance when using it.

Sometimes, you can see marginal MPG increases when using higher RON fuel in a standard car (Personally, my MPG is exactly the same if I'm using VPower, Ultimate, Momentum as it is if I use standard Shell, BP, or Tesco fuels. When I did see an increase it was because I had adjusted my driving style to see if I could get higher MPG with the premium fuel.

You'd be far better off spending less on regular fuel, and adjusting your driving style to boost MPG - unless of course your car is specifically mapped for the higher octane fuel.

In the manual for my Leon, all power outputs are stated as using 99 RON fuel and the car prefers 99 RON.
The car will accept 95 as minimum, but in the manual it says to expect a small power loss if you use 95

Oh of course - some cars prefer higher RON fuel. You're always going to get the best output and MPG from using the fuel matched to the map on the ECU.

I still use VPower though, not sure why though haha

I've used the normal stuff so far. Gunna start using v power for a bit. Will help keep the engine cleaner I suppose

To make your car happy!

I also put some 99 in the other day for the fist time ever.
