Oil changes I recently purchased a 2007 C230, how often is an oil change required? is it 12,000 miles? will a sensor come on? the car didnot have a manual with it.

these codes are slow response from CAM sensor , can becaused by poor condition oil , when was last oil change? if not recent say 6000 miles change the oil and filter , wipe codes and road teast and re-read codes , if re-appears then cam sensor could be at fault,or the sensor solenoid , what grade oil do you use ? 5w 20 is the correct grade let me know how you get on if you wish

It holds 7.3 liters, the oil change interval is 12,000 miles.

Generally, each 6000 kms. or equivalent in miles. could be two.

ALL Vehicles have the same oil change requirement

You drive 20,000 miles a year div x 5 =every 4,000 miles

You drive 16,500 miles a year div x 4= every 4,125 miles

You drive 12,000 miles a year div x 3=every 4,000 miles

So every 10,13 or 17 weeks

3,4 or 5 times a year you change your oil

before go to the dealer you can only do one thing, stop your car at flat floor for one our, then check oil level, if oil level lower or higher than lower level and maximum level it can be create engine light on, otherwise you have to go to the dealer and fix diagnose CPU in to your car and find what's the wrong, some time it's could be cam angle sensor faulty there are 4 cam angle sensors in your car have to be diagnose to find fault. however you must have to go to dealer for erase fault, is this information helped you?

all mercedes have gearbox and diff "filled for life"but it would do no harm to change them at the mileage you have done,use ONLY oil grade reccommended by merc......

Hi,
You should have a service manual that came with your vehicle when you purchased it. It will tell you how often you should change the different fluids, either in months or the amount of miles you have put on the vehicle.Most dealers have different schedules. If you don't have a records manual, you can call the dealer and they will tell you this. My vehicle says every 12,000 miles or 6 months which ever comes first.I hope I have been of some help to you.

To reset the oil monitoring system to 100% after each oil change
(approximately 7,500 miles [12,000 km] or six months) perform the
following:
1. Press and release the
SELECT/RESET button to display
“OIL LIFE XXX% HOLD RESET =
NEW”.
2. Press and hold the
SELECT/RESET button for two
seconds and release. Oil life is set to
100% and “OIL LIFE SET TO 100%”
is displayed.
Note: To change oil life 100% miles value from 7,500 miles (12,000 km)
or six months to another value, proceed to Step 3.
3. Once “OIL LIFE SET TO XXX%” is displayed, release and press the
SELECT/RESET button to change the oil life start value. Each release
and press will reduce the value by 10%.

check your owners manuel..if you have none than purchase one.
I would say leave them alone .

most car makers recommend change at around 60,000
