    Sure. I've used non det.  straight 30W  in a pinch. Belter than Low oil.

      Might wanna Change oil a little sooner than book says for synth.  Like, recc. interval for mineral oil ?

    You should use whatever Mercedes recommend, but as a one off top-up it'll do no harm to use the half litre you have to hand.

    you can, but whether is is good for the SLK, I don't know. Can you not read the oil requirements for the SLK?

    1/2 litre is going to make virtually no difference.

    Yes. You have my express permission. It may not be the recommended viscosity but it's better than running short of oil.
