GBHonestly it's not made a difference… Honestly it's not made a difference city or highway drivng. I'm on my third full tank starting out at 17.2 highway in my 2021 Yukon Denali. City I dropped to 16.4 which is normal. I made two 300 mile trips to Pa on two full tanks and I remained at 16.4 mpg. So not sure If I'm doing something wrong but it's not working...TK

GBGet More Tank Works for both of our cars I have 2012 Cadillac DeVille and my wife drives a 2022 Chevy Equinox. Both the Cadillac and the Chevy are getting 15% more mileage on each tank. My wife told me that we are never to be without this product as she doesn't have to fill-up as often. Since I'm saving real money, there no argument with the boss!
