    Hi,

    I've recently bought a W204 (S204 Estate...) C250 Cdi, and noticed that it has an old-school dipstick for checking the oil level. I have two questions -

    1.) Does it need to be checked when warm, or cold, or ie. 10 minutes after stop? I can't find anywhere where and when it is supposed to be checked.

    2.) How much oil is the difference between the minimum and maximum oil levels so if it needs topping up i can work out how much to put in?

    Thanks!

    Check it 10 mins after turning off, 3/4 on the stick before max is good......

    odd this, as MB seem to say to check when warm BUT when I was serving my time at college etc, they (and most, if not ALL manufacturers at the time) said it should ideally be checked BEFORE the engine had ever been started (ie 1st thing in the morning etc) as opposed to 10 mins AFTER a run!

    Personally, i still do it 1st thing, as a rule

    Oil that will run down will do so in 10 mins, any other oil dripping after that would not fill a tea cup and still be warm enough to allow for expansion.

    The 10 minutes after seems a good shout, and was the same i have seen on any other cars i have had/used/worked on...

    If you check the level when the engine's cold jusy remeber that the level will rise a few mms when it's hot. ;)

    Yes my W204 has the dipstick too and i check the oil when the car is on a level surface. My old yr 2000 megane had onboard oil level indicator as well as a dipstick also my Laguna2ph2 2006 had the same, yet i never needed to top up oil between changes but was a nice touch when starting the car to know your oil level

    Why do you need to check the dipstick?

    I just treat it the same as screenwash and fill mine up until it reaches the top of the spout for the dipstick. Never understood why you have a dipstick. Just keep it topped up and jobs a good 'un. :rolleyes:
