I actually think that I got better results with Gumout the last time I used that.

I already done on my truck and also few others, and result are positive.
I used it on my chevy 350, with 180k on motor, it cleaned out and have result in power, response, and also gas milege. it cleaned out lot of carbon deposits.

that's why I'm doing it.
