I was thinking about lower cost store brand synthetic oil like WM ST, Car Quest, etc. and I was wondering if they can compar in cleaning ability to name brand synthetics like M1, PP, VSP etc? Let's say they all meet the same specification would that include the oils cleaning abality?
What are we loosing performance wise from low cost synthetics compared to the majors?
