I know the SL version of 5W20 Superflo used a different chemistry and add pack from the 5W30 SL.
Is the add pack the same now in SM, since SM has all the fancy new requirements for performance?
I'm asking because when I ran LC added to my Superflo 5W20 I wound up with kinda' low viscosity in my used oil analysis [1] and I'm considering blending 5 qts 5W20 with one qt 5W30 to keep my viscosity within bounds. I hate to mix oil with different add packs, though..
