Hi pal, ive got the 2.0, refill the oil about the same as you too. Thats driving nicely about 70% of the time and putting my foot down the other 30%.
Does seem a lot but im sure its just normal for the 2.0.
by the way you enjoyin the car? Love the ride but obviously dosent give you the full Gti feel, bit dissapointed with that really.
