    Evening all

    I got a bit concern this morning when I had to add oil to my 320 ML163 and when lifted oil filler cap and there was quite a bit mayo.

    Vehicle is used on short runs - avg 10-15miles which I know is not very healthy for motor. But I know for fact it is not loosing coolant (I think) and it not overheating either.

    It is possible that it got condensation over long period of time? Should I be getting ready for checking head gasket?

    Like you I'm thinking condensation.

    Take it for a blast now and again.

    Sounds like you are not gaining water in the oil if you had to add oil :)

    I doubt very much it's a head gasket, my old ml320 used to have a fair bit under the cap

    I can live with occasional cleaning as long I know it isnt a head gasket.

    Thanks

    Could try masking off part of the rad in winter but watch the temperature gauge.

    My C280 with the 112 engine is the same in winter. Totally normal. As said above, it's very unusual for the head gaskets to go on these. Don't worry !

    Increasing the frequency of your engine oil changes will get rid of a build-up of condensation in the oil.
    Also - as stated above - an occasional long run helps.
