Hi, i tried a search but couldn't find similar. I have a C220 CDI 58,000 miles on a 57 plate. Service due in 3 weeks and today for the first time in 3 years the warning message asking me to check oil at next refuel came up. My driving since having the car has not changed. Same job, same area coverage, some long motorway trips and some around town. I drove from Manchester to Birmingham and on arrival let the oil settle then checked and level was barely at minimum. I put a litre in and later drove back and when home checked it and level near now ok near halfway. I know diesels are oil burners but i was a little suprised that never had to top up in between services in 43k miles in 2.5 years. I asked my brother who has a 59 plate C220 cdi with 98k on and he has never had to top up. I know it's not a big issue i have had diesels before that needed regular top up but with this i am curious what causes an engine that never asked for oil between services before to suddenly ask. I would like to ask the members of the forum for their input. Also I wonder what other C220 W204 owners have experienced with oil burn. I do understand a new diesel engine sometimes needs it when bedding in and also a high miler also may require it as the bores wear etc. but I am a little surprised that mid life 58k c220 suddenly required it. Thanks Ross P.s. Yeah I know I am being paranoid and the cars fine etc.
