Morning all.
I've just put the GTI in for it's second service and to have the wind noise looked at - again! This time, I've a second concern. The engine seems to be using about 2-2.5 litres of oil every 3.5-4k.
The service lad seems to reckon "up to 1L per 1000km/700m" - I was absolutely flabbergasted. Technically this means between services the engine could use 14 litres of oil - basically changing its own oil twice?!
Has anyone else noticed excessive oil consumption, or is mine really bad?
Also - the lad seemed quite insistent that a 'fuel treatment' would definitely be an idea as it works wonders, especially on a car like the GTI...as it would give the valves a good clean.

Obviously doesn't know what direct injection means then.
