Hello! I saw so many fuel system cleaners in auto store. Which one do you guys recommend or commonly used? Is it going to improve gas milage and give better performance? Thanks!

 

none, no, and no.

I use Techron every other oil change. It seems to help throttle response. It could be psychological but it makes me drive faster. So, I don't get any milage improvement.

 

if you want a better throttle response then take off the TB and clean it, replace paper gasket, take off IACV clean it and replace metal gasket while u r right there anyways.

tighten throttle cables and away you go, best 20 dollars ever spent, i am never buying another bottle of "cleaner" again, i have used many of them from many different brands like STP, Wynn's, Slick 50, penzzoil, canadian tire's mastercraft, and some others i may not remember and none of them show any significant improvement that i can describe or even notice.

 

Too many of these threads. You can google this type of stuff. All info has been given, no need to discuss anymore.
