The most effective carbon remover I have found

I have a minor in chemistry and often read MSDS ( some of them I have written). I found over 3 dozen You Tube videos that praised this formula so I gave it a try. I log my fuel, maintenance and additives for my truck 6.7 Cummins. I got a boost of over a mile per gallon of diesel with two consecutive treatments following fill ups. SeaFoam was my historical goto but it never seemed to remove carbon. In olden times, Mercury (outboard) Carburetor cleaner and GM Top Engine cleaner were effective but they had to change their formulas because of restrictions on chlorinated hydrocarbons.

Effective product

Regen reduced and the truck runs smoother. It is not a popular product but cleans the fuel system. Use the entire bottle if there is heavy sooth build up in your diesel truck.

Used the diesel formula to help clean up the tank when my fuel gauge started acting up and after 2 treatments it cleared up.
