My question is this. Lets say it does clean stuff out. How do you know it cleaned out ALL the junk and not part of it. By the time you do it every 30K, isn't it better labor wise for me to do it all at say 100K and know what the pressure and pattern is instead of guessing what it is after all the cost and work?
