Great! Thanks for posting I have done the exact same thing, went from Castrol syn blend in the KIA to now Magnatec.
A 20 buck UOA is just a small window view into the oil, although yes the common additives appear to be very similar. Just as they essentially are with about every oil posted here.
I do like the Magnatec, IMO this is a good showing for a syn blend in a turbo especially at those miles "wear" numbers (eye roll) are very good and shear resistance here is excellent given we are talking about a turbo.
