I ran FP60 in my car for about 5000 miles and noticed that after a while, it made my fuel injectors really loud and clicky after a while. I took it into the Acura dealership thinking my motor was knocking but they told me my injectors were really noisy. I discontinued using it and after a few more fillups, the noise stopped. Coincidence? Or perhaps my car just uses a strange type of injector that is incompatible with FP? Anyone else experience anything using FP? Also, after discontinuing the usage, my MPG actually went up (although it could've been many other variables, but my last fillup was 40.4mpg)
