Basically can I use Chevron Techron Concentrate Fuel System Cleaner (12 oz.) on my monte even though i have a supercharged one? is it safe will it hurt anything? does it work? i have about 74k on my monte and just want to clean her all up so she runs at her best performance for this summer, I have big plans with suspension and mods and just want to clean everything up first!

 

There is a GM TSB (I can't actually find it) encouraging the use of Chevron Techron Concentrate Fuel System Cleaner in the gas tank to clean up the sending unit in vehicles that are having problems with the gas gauge reading incorrectly.

If you can track down the TSB perhaps it will shed some light on whether its safe for a supercharged vehicle or not? Sorry I couldn't be of more help but that is all I could find on the subject.

 

i dont have the supercharger but i use the 20 oz bottle on mines and i get like 30 more miles out of a tank for a while

 

Perfectly safe to use.
