Today I changed the oil to Pennzoil ultra 5w30 (I was convinced carmax used cheap oil they had in bulk) boy was i right. The car feels very very different in engine sound and is tons smoother in transition gears. Carmax had also filled my tank for free which i would have refused too, but i was unaware they changed oil and gas. So once again i put 93 fuel and again big big difference. Pedal feel and acceleration are on a whole new level.
DANG. The day i drove my Z off the lot i thought it was smooth and quick... Changing out the oil to synthetic and 93 octane fuel only made me enjoy my car for real now!
