Peterbilt 3406 4 ¼ CAT Mechanical

I have a Peterbilt 3406 4 ¼ CAT mechanical. Been using the No-Mor Friction for almost a year and a half. It will be two years in June. My fuel economy has gone up. My heat in my gear box and transmission has gone down, and my engine has gotten smoother. I’ve gained almost a full gear on the hills since I started using the No-Mor Friction with the power.
