My car seems to be using oil quite quickly - I thought it wasnt topped up fully at the service - but checked it again today and its even lower. Does the cold weather have an effect on how much it uses?? Or am I paying the price for wringing its neck every single one of its 25,000 miles!!. It cant be engine wear at this mileage surely - and theres no sign of any leaks. (03 reg 25K on the clock)
