m going to switch back to vpower as Well since moving practically next door to a tesco grage I've been using momentum. Degitely a worse tick over and worse mpg, not felt a performance difference

I'll be doing my own test on it now. Just filled the tank with Momentum @£1.33 a litre and I'll be driving to Aberystwyth on Boxing Day but will be driving economically. Once the fuel light comes on I'll brim with VPower (provided it's not too expensive) and test again. I did have 46mpg on the way to Preston and back a few weeks ago and it was on Momentum. No misfires and definitely runs better than 95

Glad to hear your car is back in full working order! Mine is fine now after the new spark plugs and software update.

I'm still running on a mix of Momentum and Vpower depending on where I am when I need to fill up. Not yet noticed a real difference between the two.
