That Ethos must be crap because of this:
They must not understand octane, and if they don't understand that then how can they make my gasoline more efficient? They also say that some percentage of your gasoline leaves your tail pipe. Once the cat is warmed up it's taken care of in there.You Never Have to Buy
Premium Gas Again
All premium fuel is simply gasoline with a higher burning rate and more oxygen. It burns more completely, keeps your engine cleaner and comes with a much steeper price tag!
You'll get the same effects and keep your engine just as healthy when you simply add Ethos to your car with regular gasoline.
