I am a steady user of FP60. When I tried FP3000 there was an immediate difference in how my vehicle sounded under fairly heavy acceleration and at idle. Subtle, but still noticeable.
I had a hard time believing the difference so I performed a little test. I ran one tank of FP3000 to every two tanks of FP60. I did this twice. FP3000 performed better than FP60.
Next test would be to see if I have a mpg increase. However, based on how my car is running, I don't care if fuel economy remains the same. I am already satisfied with FP3000.
I would very much like to see it reoffered at the retail level in the near future.
