Sent off a sample to Blackstone on Vanilla M1 5w30 SN+
Looks good. I did notice the viscosity is lower than Mobil states on their PDS. I was surprised to see the viscosity @100c was 10.37cst rather than 11.0
5w30 version looks different than a previously posted 5w20 version here on BITOG.
Mobil’s stated specs
