I treated my '03 2500 Ram with your Fuel Treatment, and almost immediately I noticed a smoother idle, better acceleration, and the truck just "ran nicer".
The best bang though came a few days later, when I noticed my MPG (both on the trucks computer and by my own calculations) had actually gone up 1.5mpg!
We get some pretty crappy gas up here...I've tried other treatments but none did anything close to your Fuel Treatment.
I now am running Lucas Oil products in my axles and will be changing my engine and transmission over, too.
You've earned a customer for life!
