I have noticed intermittent loss of anti-freeze. I lost around 5 liters antifreeze after driving 150 miles in 3 weeks. Well, loss pattern is very strange. I usually check coolant level before and after driving. I never noticed loss of antifreeze during journey, it looks it is long time after engine is shut off and it is not always.
