Yes, but mid-grade works better

My '96 CSE has the ECU from a '98 5-speed car. It runs OK on regular but in less than half a tank I can feel the overall performance drop and can't get the boost gauge as far to the right. It will not quite reach the red and the car just feels "ordinary." Mid-grade gets it just into the red and premium definitely puts it into the red. And the car just feels stronger overall, even at part throttle.
So I don't run regular at all. The 10 cents/gallon more for mid-grade is worth it. I usually run premium in the summer (especially on trips) when temps are higher and knock may be more of an issue. FWIW, I don't find fuel mileage much different between premium and mid-grade.
