Miscibility: 

All engine oils approved by Porsche can be mixed provided they are of the same Porsche oil specification  . This means that it is not necessary to flush the engine when the oil is changed if another type of oil is used. However, since every brand of oil has a specially adapted unique composition, the same brand and type of oil should be used for topping up between oil change intervals if possible.
