Bought this car from a main dealer in 2006 with just 15K on the clock. 4 months later when my wife was on the motorway she got a low oil warning. It went to another Nissan dealer who topped up the oil and the original dealer apologised and covered the cost. Sadly the warantee on the car had expired before we got the same happening a few weeks later. Since then the problem has got worse. The car eats about 2 litres of oil every 200 miles if not more. The strange thing is, the car has never blown smoke and shows no sign of any leakage on the driveway. I've no doubt we were sold a duff car but I guess it's too late now. Any ideas what the problem might be and what the solution is? Thanks
