I have used TCW3 in my '95 Chevy truck with noticable results (been too long for specific % or even mpg gains but I got 19.5 mpg on my commute with some ecomodder tips and who remembers what else). I followed a thread on Full Size Chevy forum that got me going. It has been quite some time since I ran it in the truck. I don't commute with it anymore. In the Century, I just added the TCW3 last fillup So, results have yet to be determined.

too new, cannot post the link. The thread is titled "2 cycle oil in your gas" and has a link to the LS1 forum. ^ "Been testing"
