“Used this in a high mileage Prius, in conjunction with the Forte injector cleaner, as recommended. Took the car for about a 100 mile trip, after adding the treatment, and I did notice an improvement. Someone that had been a passenger in a trip before the treatment, and didn't like the car as it was noisy, went for a 2nd. drive with it after the treatment, and confirmed my opinion, that the car is now quieter, smoother, and has a bit more power.”
