I honestly couldn't give you a real accurate number since I haven't really been keeping track. I'm mostly around town and I'm thinking around 20. I drove this car from Orlando to Fayetteville and I think I was around 25, but it was pretty rich. I would think it's doing a little better now, but I will try to keep an eye on it now. It at least doubles my truck so that alone makes it worth it. Plus it has a nice system, so it was a win-win.
