Surely this can't be right.. I had an oil change(with filter) last January..just checked my oil level and it wasn't even showing on the dipstick(no oil light on dashboard either)so I added some new oil 1 litre at a time and in the end I ended putting 3 litres of oil in.. I'm not burning any oil and I've not got any leaks?? Any ideas? 54 PLATE FORD FOCUS CMAX 1.8 PETROL DURATEC HE.
