Hi all,

Is it normal for the oil level for our R172 decreased around 10 to 20% after its driven for around 9k mileage?

Any problems with the engine?

Please advise.

Thank You

The difference between 10 and 20% is (Either 50% or 100%! What do they say about 'Lies, damned lies and statistics...) let's call it a wide margin.
Over 9000 miles in the warm Malaysian climate, and always providing the dip stick shows your level is not approaching the 'minimum' mark there does not seem to be much cause for concern.
If, on the other hand, you haven't checked your oil level for a long time (maybe more than one month?) then you are due a slapped wrist!!

Haha... Sorry for the mislead on the 10% and 20%... In simple it decreased about 1 litre after 9000 kilometre mileage. So, is that you meant it is normal in Malaysia's weather? as we drove the car daily... The time frame for 9000 kilometre is around 5months plus.. :laugh: Please share...Thanks in advance.

Here is a web page which gives some information about oil consumption.
Excessive Oil Consumption Isn't Normal - Consumer Reports
It's written (I suspect) for the American market; a 'quart' of oil will be around 1.1 litres (a litre of water's a pint and three quarters!).
In the UK the need to put one or two pints of oil into a four year old engine between servicing/oil changes (10K to 15K klicks and 12 months) would not be 'excessive'.
You will be using your car where it is much hotter and this will probably cause slightly higher oil consumption. Also, if you are 'blasting off' a lot , which is always a temptation in an SLK, the consumption of oil, like petrol, will rise.
If you acquired the car just 5 months ago and it is still under warranty you might wish to speak to the seller about your concerns, just to set your mind at rest.
However, the most important thing is to make sure you regularly check the oil level and keep it topped up to (but NEVER over) the mark on your dip stick. Half way is good. The car will (usually) tell you if the level falls too low but it should be a point of honour to never allow that to happen! You can also take the occasional look in the rear view mirror. Take heart if you can see the envious faces behind you and, more importantly, there is no smoke from the exhaust of your car!!
Enjoy!!
