This is only the second week it’s been regularly driven as it sat in quarantine for several months. Possible the gas went bad from barely driven and it’s only just now being cycled. Hard to say. I will say that the car has been fine since it got new gas and that’s all I know for sure. I’ve done some digging and I found this thread interesting.
Guess I’ll find out tomorrow when I start my car on a hill (my driveway is very steep, as is most of SW Portland). My work parking lot is totally flat, so this might be why I had no starting issues there, but I did have a full tank.
