Yesterday I gave the ride a healthy infusion of PYB SN w/ NAPA\Wix filter. I downgraded\upgraded from QSUD SM 5w-20. I think she likes the PYB just a little bit more than the QSUD. The motor was a bit quieter. At $15 I think I'll stock up on this and save some cash compared to $19-$26 for "synthetics." PYB is the only SN I've seen on a regular basis at my nearby Wally World. Its gonna take forever for synthetic SNs to show up consistently.
