The Data sheets tell you a LOT about cold temperaturs (CCS and MRV), an hot (HTHS)
High "tolerances" in the BMW engine ???
How do the oil analysis companies determine whether they break down.
Oil pressure isn't lubrication
- Again, a bottle pour test isn't relevent, it's MRV and CCS, they abandoned pour and quasi pour tests in the J300 system decades ago.
Should have used a 0W40, 5W40, 10W40 comparison. The statement that the 0W20 grade is superior in winter...any 0W will do it.
Besides, -28C is right at the cold end for 10W...not all places get that cold...25W anything is OK in Australia even during winter.
Agree with his 0W 40/50 point for he Beemer in those cold conditions.
Well stated Shannow.
