I thought I would share what 39mpg @ 68mph looks like in oz/min in liquid fuel.
This data was from my wife's car from a recent road trip.
If your like me its nice to see a visual of the power of fuel. Then to think it is moving a car at a weight around 3000lbs at a steady speed of 68mph. I know the ICE gets criticized a lot but it is still amazing to me to see that this type of machine can do what it does and last for a long period of time without a whole lot of maintenance.
Now imagine half this amount to achieve 78mpg. "Food for Thought"
