Question about the miscible oils.
As I understand, oils if one line of the oil can be blended regardless of viscosity (0W-20, 5W-20, 5W-30, 10W-30, 10W-40). But sometimes there is a need to mix oils of different viscosities, for example (0W-20) + (10W-40) - will this mixture be completely equivalent in properties to the oil 5W-30?
Question 1: How will differ in their properties:
1) oil SAE30 (one single oil viscosity)
2) a mixture of 50/50 oils: SAE20 (50%) + SAE40 (50%) - a mixture of two oils of different viscosities.
Question 2. Spectrasyn4+Spectrasyn8=Spectrasyn6? Or there will be some new properties of such mixture?
QUestion 2. 0W-30 + 10W-30 = 5W-30 ? Or there will be some new properties of such mixture?
p.s. One interesting table:
