Correct.
Gas with 10% ethenol will burn cleaner even though it will reduce MPG slightly.

Another common ingredient in engine treatments is jet fuel (sans the aditives) which is just high grade kerosene. This is what they usually mean by "petroleum distillates"

Let's not forger that IC engine was originally developed to use a throw away by product of the distilling process (gasoline) that was thought to be mostly useless at the time.

I use Seafoam myself but, I do wonder exactly what is in it.
