mine smoked alittle bit in the beginning then started to get heavier when I rev'd her abit and then let her run.

 

Looks like rain tommorrow, taking the Blazer to work. Will finally top her off and see if any difference in the fuel economy. Will post up then. By the way according to my gas gauge up till now it seems like an improvement

 

Ended up filling her up 2nite. Squeezed every drop I could in the tank. After doing the math I went from 12mpg to almost 16mpg. That's a 33% increase after only 1 dose. Happy with the $8 investment!!!

 

thats great, already paid for it's self in savings.

 

I seafoamed my '99 that I just purchased a few weeks ago with 97k on it. Pulled off the small vacuum that goes toward the drivers fender and revved it up a bit to suck about 1/2 can in and then let it idle for a sec and then it died. I let it sit about 45 minutes and then started it up and revved it up a few times. Can we say smoke out lol. Took it around the 4 mile block and for the first mile or so there was a smoke screen behind me. Seems more peppy now and more responsive. I then poured the rest of the can in the tank. First road trip with it, i got 19.5 mpg. I then noticed the air filter was a bit dirty so i changed that. It has more power now that it can breathe. I bet it'll get better mileage now too!!
