Review on Red Hound Auto 2013 2019 Compatible by Broderick Shetler

Can't say for sure. But every day I drive to and from work the same way. I average less mpg. I usually average close to 24mpg. Because if you add them, it's difficult to average over 23 without an absolute nanny. There were also bumps on the back that needed to be cleaned with sandpaper. They appear to be durable but upon closer inspection I'd give the fit a 5 out of 10. Having said all that, I would dry another brand if I were to buy them again. Not that another brand would have influenced the MPG any differently if they came close to the same design. I would switch manufacturers based on the fit and finish of the product alone.
