Today, I decided to dive into something that’s been on my mind for a while – figuring out what exactly is going on with my car’s fuel consumption. It feels like I’ve been filling up way more often lately, and I wanted to get to the bottom of it.
Getting Started
First things first, I grabbed a notebook and pen. Old school, I know, but it works for me. I needed to start tracking how much gas I was actually using.

I started by filling up the tank completely. Made sure it was clicked full, you know? Then, I reset the trip odometer in my car. That little button that sets the miles back to zero. That’s our starting point.
The Tracking Begins
For the next couple of weeks, I just drove like I normally do. To work, to the store, the usual errands. Every time I needed to get gas, I did a few things:
- Noted down the mileage from the trip odometer.
- Filled the tank all the way up, just like before.
- Jotted down how many gallons it took to fill it up.
I kept doing this every single time I got gas. It felt a little tedious, but I knew it was the only way to get some real data.
Crunching the Numbers
After a few fill-ups, I had enough information to start seeing some patterns. I took my notebook and did some simple math. I divided the number of miles I drove by the number of gallons it took to fill up the tank.
For example, if I drove 300 miles and it took 10 gallons to fill up, that means I was getting 30 miles per gallon (300 / 10 = 30). I did this calculation for each fill-up.
The Results (and Some Thinking)
Looking at the numbers, I could start to see how my driving habits were affecting my fuel economy. When I did mostly highway driving, I got better mileage. City driving, with all the stopping and starting, definitely used more gas.

It wasn’t rocket science, but seeing the numbers laid out like that really made it clear. I also started thinking about other things that might affect fuel consumption – tire pressure, maybe even the kind of gas I was using. It’s a work in progress, but at least now I have a better understanding of what’s going on, and I can try to be more fuel-efficient by making a small adjustion in daily life.
