Monday morning to work (the day after) the car drives really sucks..... Gerald advised me to drive it gently, as I do now. It really like someone having a bad hangover the next morning...
Tuesday, oil level back up again, I can reach almost 6 when driving and above 2 when idle. Today is low again. Driving it gently feels fine, quite good actually, but not when the boost comes up, then all the flat spots are back laughing at you. Nothing I can do except just back it off and drive gently again.
Good for my fuel consumption though...
