I tried ethos and it did absolutely nothing. I am one of the less sceptacle that will try something once or twice mind you if its cheap or free.

The only additives I've ever found to affect my mileage are

1. Mystery Oil
2. Acetone

Mystery oil (especially the kind that isn't approved) has always had an immediate and noticeable effect, especially in my old junkers and diesels. And obviously my mileage goes up a couple MPG.
