Definately don't drive the car otherwise you will wipe all the bearings. Obviously you haven't been checking it weekly as with most of your other levels. As APAV said buy the correct ACEA oil, which will be C2, nothing to do with the viscosity rating.
I have just changed mine using a new Mazda filter, drain plug washer and Castrol Stop/Start 5W-30 C2.
The C rating is an oil with low Sulphated Ash 0.6%, C3 is 0.8%, this is what clogs up the DPF and in turn causes the regens. Fewer regens = Lower oil
contamination.
