Review: Seems to be the Best
Review: Well, i was skeptical, but the treatment works well ! Added 1 can to 20gals in my 2000 7.3 diesel van, and within the 1st 15mi noticed that when i tromp on it from a dead stop, the "black cloud" was about half as dense, and spewed out bout 1/2 the distance (til my speed and motor RPM picked up).... Added another can after i put 15 gals of bio-diesel ina almost empty tank.... "Black Cloud" of soot was still less than after 1st treatment and length of "cloud" was shorter (upon wicked acceleration)...FYI, i have a "performance chip" in it, which spools up the turbo quicker than stock programing.... I'm sold !!! Have not taken a "mileage" check yet, cause i added treatment both times without knowing how many gals i had in the tank.... Will fill her up , do the math, and report back at a later date.... (Lil background-my injectors were replaced 150k miles ago and was getting 16-17-18mpg on the highway-not pulling a trailer). Steve
