The 5W50 Oil is no good for ML.
This engine dont need very tick oil.
very important for the engine to have very fast flow of the oil.
the formula 5w50 is very wrong for ML.
no all synt.oils are good.many of them are very bad.
look fo europiean formula oil.229.3 and 229.5 - MB spec.
5w40 - 0w40 and 0w30 with MB spec.229.5 very good.
I use on my ML 10w30 AMSOIL.110 000ml.eng.not burn the oil.
