Product does not work, no call back

Used this product in my OTR truck along with the Efficiamax oil engine additive. No increase in fuel mpg with the fuel treatment and the engine had major issues after adding the oil additive, it looked like honey and was very thick, I had to replace bearings and oil pump within 100 miles. Hurt my engine bad.
