Im going to man up and admit I was TOTALLY wrong about this stuff. I never believed it to be any different than Gulf or sonoco or Texaco..ect 93 octane. But Ive been using this stuff for the last 2 weeks now (only cause I was given a gift card) and maybe its somehow a coincidence, but my car is running much better, especially cold starting. Ive never had trouble getting it started, she fires right up even at 5 below, but she sounds smoother and more quiet then ever before, and I havent done anything else that could have affected it. Getting on the highway....she is quicker I know it. Anyone else notice a difference with it?
