Has anyone tried any of those "gasoline additives"? I bought the Ethos a couple months ago after seeing that 3 or 4 news stations had done positive reviews on it - said to lower emissions and increase mileage also. I have not used it yet as I am waiting until I go back to school (a mere 2 weeks away. Ack! Where did the summer go?!) since I know the exact mileage I get on that route everyday.

I have a 1999 Saturn SL2 with 131,000 miles on it, and it usually gets between 28-32mpg. I have an hour drive each way to school and back do if I can do better than that it would be very helpful.

Wondering if anyone has tried these products, especially the Ethos and has any feedback.
