Probabaly been mentioned countless times but Paul a lad posted in one of my 8L threads this link; Thorney Motorsport - Fuel Test Results Update It basically states that Momentum99 is better - now as far as I know the V-Power we have over here is 99RON and on the contintent they have 102RON in areas. Which do people feel is better to use? Ever since I've had the A3 I always used V-Power and I think that's more from people's opinions about running the higher octane fuel in the turbo cars as it also keeps the engine clean etc etc. I would imagine that before I had the car it was ran on 95RON 'whatever was available at the time' fuel as I bought the car completely standard and it had been a business use car for the first 6years. But read in a few threads below that a few have started using Momentum99 - I don't really fancy swapping and then suddenly coming to an area where Momentum99 is unavailable as I would rather stick to one fuel. Discuss!
