I'm assuming your vehicle is NOT on the new 10k/yr OCI?
My vehicle is in the 10k/yr OCI category.
Is there a comsumption issue with M1 0W-40 vs. Castrol 0W-40?
I don't know about the Castrol, but the M1 0w-40 is the lowest in terms of consumption in my M5. 1L/10,000Km.
Correct me if I'm wrong but I thought you mentioned you got better oil consumption with PU 5W-40 or was that not for a full 10,000 kms?
My high mileage 328i has low oil consumption (1/2L/8,000 kms) on a light (HTHSV 2.9-3.0cP) 0W-30 blend. Heavier oils I've run in the past were no better.
Nope, was not the whole 10K Km's. The PU consumed at twice the rate (2L in 10K) as the M1 0w-40 (1L in 10K).
