Hey guys, I have ~16000 kms on my car and I got a msg for check engine oil, is that normal? What should I do? Also, any time I hit the accelerator, a metal clanking noise comes from under the car, anyone know what that is?

Thanks guys

Yes its normal. I carry a bottle of oil in my trunk. My car burned nearly 2qrts in its first 5k miles but after that its settled down to 3/4 quart every 4k miles.

The other noise.. IDK... doesn't sound normal. Is it a new sound?

I wish - for their own sake - people here who rely on the check oil warning would pull the dipstick every few weeks and check it that way. No offense but trusting a sensor for something that vital IMHO is just .

@2012C63AMG - the noise is fairly new, I have service in 1000 kms, so I was just waiting for then to go to the dealership.

@bhamg - no offense taken. I don't know squat about cars, so thats why I posted about such a basic thing. This is my first AMG. I have been driving S classes for 6 years, and never got these messages.

If that light is on you are really low.

Have you not gotten an oil change, please don't go 16,000km without an oil change. Do it every 10k KM.

Dont drive it until you get some oil in it (Mobil 1). then limp it to the dealer asap. sounds like something could have been damaged. hope not.
Normally (but i could be wrong), when the standard oil light comes on in any car it means you have little or no oil pressure. this is very bad and you must stop immediately. however you are normally pre-warned by the cars sensors if the level is dropping (on modern cars), this is what normally is displayed on the cars computer screens.... I was always told to manually check oil regularly and if for what ever reason the oil "light" comes on - engine off immediately...

What's the level trigger for the light?

bhamg

I think it's about 3 qts down from the upper (full) mark on these engines. On the six cylinder I put 2 qts in a friend's car to bring it to the upper mark once she got the warning.

So if our cars normally take 9qts, that would only be 2/3 full to trigger the alert. I wonder if anyone has graphed how much oil our engines "lose" compared against mileage on the engine. I'd like to know if this is typical or atypical.

Completely agree with you

Based on comments on this board oil consumption seems to vary widely on the C63's but most do consume a fair amount of oil early on. I used 8 qts in the first 10k miles. Now it's stabilized at one qt every 3.5k miles. Many M156's seem to guzzle oil for a while and then settle down between 10k and 20k miles.

This post is BS.

If you are unsure how this oil issue works, take your car to a MB dealer, have them explain it to you and they will top it up free of charge while you wait.

When this light initially appears it means you need to check the oil level at your next convenience, it doesn’t mean drop everything and ‘head for the hills’.
If it did, 99% of MB owners would be blowing up their engines.

Have the dealer show you how to check it and how to top it up. It does settle down after a while.

As for the metal clanking noise, that would worry me.
If you have no means of checking that yourself, I wouldn’t wait for the next service, I’d have the dealer check it now while they teach you about the oil issue.

Before you claim other people's help and comments are "BS" i suggest you check your facts.

I never said it was gospel what I "thought" was correct, which is why i said "i could be wrong". I was merely trying to offer helpful suggestions to a fellow member.

Your reply had me doubting myself so I just phoned the head mechanic at my local MB dealership (who i happen to know personally) and asked him. He confirmed i was completely right.

When the standard oil light comes on it means you have very low oil pressure or the sensor is faulty, which is bad. He said most modern engines have either gauge or sensor that pre-warn the driver before the critical stage through the cars display "check engine oil level" (or similar).

If you still don't believe me or what MB say. Do a Google search! this is the first page:

This is the last time I comment on these matters as i cant be bothered with the replys like this. i am only saying this for "Multani" benefit.

While low oil is bad in the long run if you continue driving, it is not the end of the world when the light comes on. during engine design and testing manufacturers will actually run the engines without oil till it implodes on itself.

When the light comes on, go to the nearest gas station if your not near an MB service center, and just top it off.

Some cars (such as Porsche GT3s) do not even come with a dipstick. You have to rely on the level sensor in the oil tank. Never heard of one failing and the readings are reliable.

Just saying.

Serge944

My light came on the other week at 2400 miles. When I checked the oil level, it was actually about a quarter above minimum. Appears the system gives you fair warning.

The light is definitely not triggered at 3 quarts as stated above. The difference in level from minimum to maximum is about a liter.

b16

Exactly.

When my light comes on (at first I wasn't aware this car consumed oil so fast, no other car I've owned has) I need to add 1 or 2 quarts usually. There is still plenty of oil in the sump and pressure would not be an issue.

There is a secondary light that comes on when **** gets real bad (low pressure).

b16

That link is about oil pressure, not oil level. Two very different animals.

bhamg

The difference between the top of the (top) two markings and the bottom of the lower marking is 3 qts.

And this is probably one of the reason why I never browse here anymore. People just want to get wheels and CF accessories and have no idea how any of the car's mechanics work. Some don't even know how to check the oil.

flomofo

Teach them then.

So far I have put on 7000kms since my last oil change (I change every 7500-8000kms) I've had no noticeable oil consumption. I check my dipstick every 2 weeks.

This must be a good sign!

Good to know.

Hey guys thanks for the input. Took the car to the dealership and they had to put 1.5L in.
Sorry to those who are agitated by posts like mine but people like myself have to learn somewhere. Forums, I believe, are for people to befriend eachother and provide help. Buying a fancy car doesnt mean you must know all aspects, not everyone knows everything.
