I'm not sure what you mean but our cars take 5.5 litres of oil . If the oil goes high on the dipstick after 150km it's because the oil has expanded. It shouldn't go much higher than 1 cm though from the maxafter 150 KM driving, when I check oil level I see 1 liter more on normal level
Instead of 6 liters may go 7 liter
did you engine rattle on start up after sitting a bit? did you find a solution?Hello,
I have the same problem now with my W204 c250 2013 coupe. The fuel gets into oil, it seems that the engine is not working nicely when it is cold. I have changed the spark plugs etc. but it did not help. One car repair shop told me it can only be because of high pressure fuel pump. Other guys took it out and said it is impossible because it has enclosed system and cannot mix oil with fuel. I don't know what to do, did you guys find a solution to this problem??
Possible blown head gasket. White smoke, low coolant level, and white stuff under the cap all indicate water in the oil.mixing petrol with engine oil
So first of i have a C Class model C 180 CGI W204 - 2010, and i had this problem last year and here is what i did:
1. Took it to a MB dealer ( Vse va?e priljubljene znamke na enem mestu | Avtohi?a ?epin ) and they said this is nothing and due to making short trips (15 km to work and then back so ~35 km a day) it probably just some condensation in the engine. They changed the oil and oil filter and said i should drive it on longer trips. They also said there is no way that petrol is mixing with engine oil. After two days it was back to white smoke and more oil in the engine than max on oil dipstick.
2. Took it to a friend to change spark plugs as we thought this could be the problem and again change the oil. This did not fix it.
3. Took it to MB dealer in Ljubljana (Autocommerce - Mercedes-BenzAutocommerce) they did a diagnostic on the car and told me that the high pressure fuel pump is the problem. They wanted to charge me 1700€ to change it. I did a little research on the internet and ordered a high pressure fuel pump from Welcome to the online shop of the genuine car parts pro’s (Benzin pumpe for Mercedes C 180 CGI BlueEfficiency - 2010 Nr: A2710703501) Then took it to a local dealer and they changed it, so the car was running fine and i was relieved that i solved the problem.
4. This winter i noticed that the car was acting funny, so today i checked the oil and guess what again the white stuff on oil cap and more than max on oil dipstick and a strong smell of petrol.
I also noticed that the cooling liquid was low.
Any suggestions what is the main problem for this, i think it has to do with winter and the cold, because the car was fine the whole summer.
Tanks in advance for any suggestions you guys may have.
Check for exhaust gases in the coolant.Possible blown head gasket. White smoke, low coolant level, and white stuff under the cap all indicate water in the oil.
