This is dads 99 z71 with 100k + miles

 

lol good stuff though

 

Cough cough.....at how many miles or when do you do this? What are the results?

 

i think every 8 to 10k miles is recommended. I just do it when i can feel the truck running a little rough at idle. (kinda hard to explain) Ya know when you can feel a lot of vibration from the engine, it makes it run a lot smoother. Helps a lot with that and throttle response. Huge difference if you have never done it. If you have ever pulled the intake and throttle body off you can see all the carbon buildup, or whatever it is. I had chunks of it in mine and i run 93 and mobile1 so i dont know what else to do besides this.

 

damn, I've never seen one smoke that much afterward!!!!!!

It either screwed that motor up or cleaned a hell of a lot of gunk out. lol

 

sounds like i need to do that to mine, 160k and i seriously doubt its EVER had anything like that done

 

stuff is fun to play with....the white smoke isnt the junk burning..its just the product itself...no differnet really then other full injector type products..just makes for a good show

 

lol like i said its got i think 110k miles. and its never been done to it. when he was leaving in the pic he was going straight to GA for a business trip and he hasnt called with any problems. Im gona vote it cleaned out a lot of junk.

 

did you put it in the fuel tank?

 

he needs to change the oil SOON
