for 1.4tsi owners i thought id add an invaluble resource from one of my cupra lads.
http://www.seatcupra.net/forums/showthread.php?t=407682&highlight=luciferbut basically to keep a 1.4Tsi happy you need these things:
Plugs- NGK BKR7EIX 2667(ever 15k) cost £25
Oil- 5w40 (quantum platinum/Castrol edge/millers nanodrive) (every 10k) cost- £15/£30/£50(rough)
Decent fuel- Vpower/Momentum( the amount of timing/boost/compression on these wee engines is insane, please dont put tat in it!)
dont drive it like a pansy, get it up to temp then romp on it, carbon build up is the reason for alot of missfires.
