Synpower API SN looks really good in UOAs posted here.
The main rap on earlier Synpower was weak TBN retention, but this appears to have been remedied.
If I didn't have forty quarts of HGMO SM 0W-20 plus sixteen quarts of SSO 0W-20 plus a jug of FAR QSUD 0W-20, I'd have been all over the NAPA labeled Synpower 0W-20 at $3.49/qt.
Also, while you may have to fudge date in service and mileage a little bit, you can register your car on both the Pennzoil and Quaker State sites and then get MIRs which will make a jug of PP 0W-20 around five bucks after MIR and a jug of QSUD 0W-20 FAR.
This explains the current fill of PP in our '12 Accord.
Had I waited a week, until after I hooked up with the fellow member from whom I bought the HG, it'd be running that now. It will be getting HG in the next few weeks, since the MM will hit 15% over the next few weeks, just in time to get the oil changed before the coming of real cold.
