My 2013 Toyota FJ Cruiser with 138,000 miles is getting almost 18% better MPGs. After eight uses, my mileage has increased from 20.4 mpg to 24 mpg. I’m basically getting over 2 free gallons of gas per fill up. My V6 engine now runs like a V8! I had started my car in the garage and I left it running for 15 minutes and when I returned, I could not smell any exhaust emissions which was absolutely incredible.
