I bought a 2010 C250 from a Nissan Dealer near my house. Car is clean and I do not have any concerns about maintenance, etc. Nissan did an oil change on it and diduse their synthetic oil. They are no stranger to performance cars such as the 370Z and G37 models. I do not know what brad oil they use. I checked the oil 'hot' and it appears the oil is over the max line... to be sure about correct oil and level, should I just book it in at Benz for a quick oil change? I have a B service coming up in 260 days and I ill redo it then again.

Thoughts?

Can't you just ask the dealer what oil they used? How much over the max line is it?

dolvio

I emailed the sales manager and am waiting to hear back. Dipstick of course has a min and max. I am not only past the max but at the top of the red measure. Checked when engine off for 30 mins.

So they filled with too much oil, that alone may be a good enough reason for you to get a oil change unless you feel like extracting some of the current oil out for now.

Ya I am going on Wednesday. I have driven about 150kms. Should be fine. I believe you need to be a HELL of a lot over to do real damage.

Except that the synthetic oil that Nissan uses in their applications most likely does not meet the MB 229.5 spec which your car needs.

Nissan recommended oils are typically geared toward fuel economy and hence have low HT/HS viscosity. On the other hand MB 229.5 spec requires HT/HS viscosity to be at least 3.5 cP.

Probably not going to cause a catastrophe in your engine if you were to leave it in there for one oil change interval, but if the car is under warranty, it's probably better that you have a record of the correct oil going in there.

Even MB dealers are notorious for overfilling the engines, especially the 4matic ones which take 1qt less oil than the RWD ones. Every time I let my MB dealer do the oil change, I end up having to extract at least a quart of oil to get it down to MAX level on the dipstick. Otherwise, I get a "Check oil level" warning on the dashboard after extended driving.

Yes, I'd change it. Not only to correct the level but because they almost certainly did not use the correct oil.

dolvio

I'm going to redo it tomorrow at Mercedes. I don't need to go anywhere today either. Why does MB always overfill??? I see that people all over the place have this happen to them...? What gives? I have a 4Matic BTW.

Pete7874

For 2008 and 2009 model years, all the MB literature was showing the wrong oil quantity for the 4matics. Service shops just went blindly by this literature. MB never bothered to correct the literature, so the problem persists.

Now, yours is a 2010, and the literature is correct for this year, so maybe you won't have that problem.

dolvio

Well this probably went on for years and years with 10's of thousands of cars... So an overfill isn't the end of the world. I have read that you need to put in lik 3-4 extra litres to actually cause any damage. I live in Vancouver, Canada and most of the cars here if not 98% are 4Matics. They should do it right. I will d a quick check before leaving the dealer.

If I'm getting the "check oil level" warning, something is not right. There's always a risk of oil getting into exhaust and prematurely poisoning your cat. New cats are expensive, alas, I think there is an extended emissions warranty on them, at least in the US.

dolvio

Oh I agree. Question: Do ALL the W204's have a check oil light come on if oil is too high? I guess too high of a level and pressre would be too high? Correct?

dolvio

I was told today that Nissan used Mobile 1 synthetic. Still an overfill. For some reason I just can't get comfortable with this and am planning on having Mercedes do it properly tomorrow. And what I mean by properly is having them do it and me checking afterwards.

Thoughts?

Ikester

what viscosity did they use? If its correct, then i would just drain out the extra oil.

Pete7874

OK, but which particular one? M1 0w-40 meets the MB 229.5 spec. Most other grades of M1 don't.

dolvio

That's my whole point actually... I don't know what's in it. And what if they didn't even put that in? I just blew $30 grand on this car and would rather spend another $200 to sleep better at night.

2010 C250... Canada, eh...?

dolvio

Yep, we can only drive 4 months a year. The rest of the year we have our snow shoes on and use sleds. No joke!

How much did the insurance co give you? Did they fight you over partial liability?

dolvio

The accident was 100% the other drivers fault. I was paid $25,635 total including tax. Not bad.

Nice. Similar situation happened to my dad. And my dad drives SLOW. Like 10 mph under speed limit and he was just going straight. Some 17 year old in a maxima plows right into him. They had to fight for 10 months before finally admitting it was 100% his fault

dolvio

In my case a girl turned in front of me. When a turn happends they are always at fault. In your dads case I could see the argument... right or not...

xjaymzzx

My dad was going straight on a 4 lane road. And the 17 year was trying to make a left hand turn outta parking lot lol

dolvio

Brutal. This is my 4th accident in two years none of which were my fault. I dont even like driving anymore.
