Castrol synthetic or Valvoline?

My last two oil refills (2 Liters total) where done with 0w20 synthetic.
Engine had some mixed 30 weight oil in it.

After a long drive with highway and city driving, my hot oil pressure still hovers at 30psi with 500-550rpm in drive, and close to 60psi when driving.

The 0w20 oil bottles read 'For hybrids' on the label. Since my Dart uses oil and burns propane, I find that classifies it as a hybrid nicely... :D
