I heard some negatives about Power Service a few years back and stopped using it.
Power Service is an emulsifier, so it basically absorbs any moisture that may be in your system and is running it through your injectors (ticking time bomb)
Stanadyne and quite a few others are de-mulsifiers and will separate any moisture out and let your water separator do it's job.
People should drain their fuel bowls now and again prior to a potential water warning in fuel light.
