I have a 2010 Mercedes-Benz C250cgi that's clocked up only 75,000km.
I gave it an oil change yesterday using 5W-40 Penrite HPR5 oil, which is Mercedez-Benz approved and quite a popular and expensive oil here in New Zealand, and i also changed the oil filter while i was at it.
All seemed well, at least until i took it for a drive later that afternoon. After driving it for a good 20 minutes there was a strange noise coming from the engine, like a noise from a diesel tractor, similar to an old clattering engine that's struggling for life. The sound only lasted approx. 5 seconds but long enough to scare the shit out of me and so i promptly drove it straight home which was only 5 mins away.
Fast forward a day later (today), i decided to jack the car up and i took off the undercarriage plate protecting the oil sump, all looked good, no oil leaks and all the screws for the plate were re-installed correctly. I then lowered the car, checked the oil filter was installed correctly, i could see oil inside there, it looked ok. I then checked the oil level, it looked low! Bizarre... considering this car takes 5.4l of oil and i'd put over 5.6-5.7l in there! Anyway, I put more oil in, and in the end i would say there is now 5.9l in there! Surely it's too much?! But the dipstick says otherwise and is showing just below full... strange, but ok.
After completing the above process i then started the car so i could re-check the oil level after it had circulated around the engine. I left it idling for a few minutes, all seemed good, but then i decided to rev the car to 2k RPM to speed up the process. After hitting around the 2k RPM level the car then spluttered as if starving for air (or oil) and so i quickly turned the car off. I re-checked the oil level, it looked ok. I then started the car again, and the same thing happened. I no longer want to turn it on, just in case, the car didn't seem to like it.
What on earth could be wrong with it? The strangest thing in all of this is that there hasn't been a single error message or check engine light pop up on the dash, and i know these Euro's are sensitive!
Any ideas?! I need the car for work so need to sort it ASAP! Thanks!
