The problem with the name-brand Synpower is that it's inferior to M1, Edge, PP, yet it costs more than them.
However, the private label Napa version often goes on sale for $3.79/qt, which is a great deal for it.
We will see as my current fill is with Synpower and I will be doing a UOA @ 6,000 miles which will be 1,000 miles more than the PP that I just had a great UOA with....I am thinking Synpower's UOA should be just as good as PP. Also, I don't think that the Napa house brand is quite the same as Synpower.
