I've started to get problems with the oil consumption too the last months. I bought 1L oil 19/4 and I've been forced to filled in everything and I've only been driving like max 2000km...? No leak, no smoke and loss of power either. Any ideas??
I got a major engine overhaul under warranty - new piston rings, new engine head, new valves, new oil pump, new pcv valve
done 8,000km since the rebuild and no drop of oil consumed
