I’m doing an experiment for the next week. I want to know how much gas I save by slowing down a little on the highway.
I usually cruise at around 85-95 mph, but this week I’m topping out at 70. Because I’m only doing 70, I don’t have to speed up and down as much to get around the morons driving slow in the left lane. This may affect my mileage more than the extra wind drag created by the speed.
Driving into work today sucked. I’m just so used to driving at a higher speed that it felt like I was putting along. I don’t think I arrived much later at work though. Granted, I don’t work that far from my home. A longer trip could definitely affect the time it takes when moving a slower rate of travel.
I imagine that I’ll get used to traveling at just the speed limit after a while. At the end of the week I’ll fill up and calculate my mileage. I’m starting out @ 23 MPG combined city and highway. I won’t be changing my routine so the results should be comparable.
