The Subaru has spent most of the past 80K since I got it on PYB, Formula Shell, and QSUD. PYB is the quietest oil in it.
The Olds will be getting the QS green bottle I have on hand, and likely go to QS Defy or PHM once I'm out of it, baring odd consumption or leaks occurring from getting an old low miles low use vehicle back on the road.
