Very impressed with gas mileage

Did you verify your speedometer reading was correct with GPS? If that was reading high it would have given false odometer readings as well. Also how did you measure fuel consumptio
2.76 gear most likely, and I bet the tires are a little taller than stock. Sounds reasonable to me. Non A/C car? Power Steering?

I verified the speedometer and odometer reading this evening. Speed is 4mph faster than gps and odometer is dead on mileage wise. And that’s all that matters. So my calculation was spot on.
