This is one product that actually does what it says it will do.... I put it in my 2013 Elantra that usually gets around 32-33 mpg. Using the prescribed dosage and going thru 2 tanks of gas (20 gallons) my car had more pep, smother exceleration and my average mpg was 40.9 mpg!!! I highly recommend this product.
