If my car is 56% better on fuel than can I say this?

  • #1
If my car goes twice the distance on the same amount of fuel, doing twice the distance the friction and wind resistance is double.

Can I say my engine uses fuel 4 times more efficiently?
Or is it only double?

My thinking behind it comes from Ohms law, if you double the voltage you get 4 times the power to the same load.

It is only double. You are double-booking.
