for those not familiar w/mixing viscosity...
for OP's case:
0w16 m1 afe = 7.6 cst @ 100 C
0w40 m1 Euro = 13.8
5w30 m1 black label = 10.8
using the vscosity calculator:
https://olezol.com/mixing-blend-viscosity-calculator
50% 0w16 and 50% 0w40 = 10.15
30 weight starts at 9.3 and goes to 12.5
job done, unless you want 11-12 cst oil
