has anyone used this before? was there improvement?

EEEEEKKKK

 

Back away from the additve .....

 

Anything that says its going to flush or cklean part of your engine is not a good thing. The only thing that seems to work well is seafoam.

If you burn it im all for it, if you add it to one of your liquids that you dont burn i'm not.

what is better to add the seafoam to the gas or to the injector? and how do i add it to the injector?

if you add it to the gas tank it's going to go through the injectors...

 

I seafoamed my car through the pcv and gas tank. It made a lot of white smoke and I think it helped.

how do you do thru the pvc value?
