I heard u lose about 10% of your perfomance if you use the 95ron over 98ron
Chuckie maybe a few fills of the tank with VPower and you'll be able to tell a bit of a difference. Iv had my TFSI FR since March and iv only used VPower. Dont see much of a point in spending £16k on a sporty car then skimping a few quid a week by using supermarket fuels.
Not that il be keeping the car forever, but if supermarket fuel is regularly used in a car thats reccommended a higher octane petrol, does this shorten the life of the engine or are there bound to be any faults related to this?
