I'm talking instant mpg and power just after putting gas in. Which lasts till i park the car and it sits overnight. Normally i do ten miles after a fill before i get home, so i don't know how long it could last. I'm not saying you could improve your mpg for a full tank. But there is definitely something going on with how an engine runs just after putting some gas in.
