Quote from TT:
However, never, EVER let your car go down to the minium - because specifically on the GTI - the total sump capacity is 4.6 litres, so by letting the oil level drop to the min, you have basically just lost 20 percent of you lubrication abilities!
TT, I really thought you were in the know!
The lubrication abilities of an engine is not proportional to the percentage of oil sump capacity.
As long as there is sufficient oil in the sump to avoid the oil pump sucking air and to allow for a sensible cooling cycle there is absolutely no difference in the 'lubrication abilities' between a sump at minumum or maximum.
I am certainly not condoning allowing the oil level to be at minimum but the greater danger is over filling (destruction of cc, etc) so best to maintain level half way between max and min.
