I am an Amsoil distributor and I still use Techron in my cars/trucks.http://www.amazon.com/3M-08963-Fuel...47JO/ref=sr_1_1?ie=UTF8&qid=1323943229&sr=8-1
You can do this, which will help keep the TB clean. I'm with Hcvone, I use a bottle of "Techron" from the store or I use the PI fuel treatment from Amsoil.
Here are some links to the products and stuff I use with great results:
If you use a top tier filling station you really shouldnt need it, I add a bottle in my tank about every 5k miles. The product you are asking about is very good. It also keeps the fuel level sensor contacts clean..Do you recommend the use of the ACDelco/GM Fuel System Treatment Plus (for preventative maintenance) If so when/how often should we use it on our vehicles?
