wind has an exponential effect on mpg, punching a hole through 5mph wind is pretty easy at 35mph, but at 80mph a lot harder!
im just happy to hear someone properly taking care of their car with gear fluid changes  |
The same is true for still air, as speed rises so does wind resistance. This is why cars are designed to be so aerodynamic
