Save Money (25%) On Gasoline (Really!)

I wanted to dig into my fuel expenses, so I put the graph together below. I already automatically track my expenses is MS Money. A few minutes searching got me to a .gov website with official weekly gasoline prices. And so the graph below:

The green line is the weekly gas price (in cents - right vertical axis). The blue line is my actual expenses. That was pretty volatile, so I added a five week moving average (black line).

You can see in the last 3 months my bills have fallen by almost 25% even as gas prices have continued their upward march.

How?

I've been scrupulously following the speed limit, avoiding 'jackrabbit' starts and trying to keep the engine below 2500 rpm at all times. I also minimize braking whenever possible, allowing friction to slow the car down.

It's doing wonders for my mileage. In an age of rising prices, cutting consumption is the key to holding the line on inflation!
