Only going by kinematic, it is heavier (slightly) at 40C. That's just going by the PDS data.
Obviously as the temperature gets lower there's a crossover.
But as you know the KV100 spec' is more about the oil's chemistry when taken in the context of it's HTHSV rating.
Case in point, which is heavier M1 SM 0W-40 (KV100 14.3cSt, HTHSV 3.6cP)) or M1 SN 0W-40 (KV100 13.5cSt, HTHSV 3.85cP)?
Or to really throw a wrench into the works, M1 R 0W-50 (KV100 17.2cSt, HTHSV 3.8cP?
