as far as i know there is no leak at all, the car park at work is crystal clean and wen i move my car after work i check, nothing there, i dont think the oil is leaking at all, the engines is just burning it up, mind u the helpfull stats posted said 1 litre to a 1000 miles, iv done 4000 miles in 4 months wivout having to top up, just the smoke that concerns me now
