Before I decked my block with new combo, I had decided to run only the GOOD STUFF. The car ran like sh@#t. It stumbled, hesitated and performance seemed off, and was not responding to jet changes. Never thought about the fuel. As fate would have it, I was out street racing one weekend and ran low on fuel. I popped into the Chevron and topped off on premium. By the time I got back on the main road, the car smoothed out and ran like it had in the past.
