FYI:
I Switched to Magnatec -> 2000km took it from 'Full' to 'Low' on the dipstick (I think thats about 500ml to 800ml).
Thats a bit more reasonable (still higher than any other car I have had), but I was told by a Toyota Mechanic that most 4age's consume oil regardless of kms or condition.
Castrol 15w40 was the previous oil (which it really seemed to go through).
The engine seems to rev better with the Magnatec, and it runs a little bit smoother (Also recomended by every mechanic I have spoken to).
