I take it easy driving the car. Not knowing the condition of the rotating assembly or heads, I don't want to blow something up stomping on the accelerator. I use 93 octane premium in the car and recently switched to Valvoline VR1 oil. I believe the PO was pretty hard on it, but it sat for about 4 years before I got it.
