Star Tron : 95% naptha
SeaFoam : 25-35% naptha, 40-60% pale oil
Liqui Moly and StarTron are better at fuel preservation and cleaning the intake path.
Seafoam is more multi-purpose. In addition to fuel preservation and cleaning the intake path, you can safely run it in your oil before an oil change. Ideally you should never have to do this. Run good oil and keep it clean. But if you have high mileage engine that lived a life of neglect, it really can help extend the time before an eventual rebuild.

MORE benefit for port injected engines (HEMI, LS1-9, Pentastar, etc).
For DI engines I run one bottle a tank before the oil change. Kia and Hyundai made this a recommendation long after I started doing it with my DI engine.
