![My Car's Mileage and Miles (Odometer) Since November 2012 [OC]](https://www.byteseu.com/wp-content/uploads/2025/12/4j3y5smem7ag1-1536x709.png "My Car’s Mileage and Miles (Odometer) Since November 2012 [OC]")
I have been using an app on my phone where I enter Odometer, Gallons of Fuel, and Price per Gallon every time I fuel up the car since I bought my car in November 2012. The left Y-axis is Miles Per Gallon and the right Y-axis is Miles recorded from the Odometer.
I exported the data from the app to a csv file and created the graph with LibreOffice Calc.

Is that a working-from-home elbow on the red line?
You’re incredibly disciplined if you’ve been filling it out manually for so many years
Clearly a downward trend with your MPG. Curious what kind of oil you’re using and if you got regular tuneups completed, i.e. spark plugs, fuel filters, air filter cleaning, etc.
Car details? Year, Make, Model, Trim, Engine, Transmission?
Mind sharing these data? These would be a great case study in Gaussian processes for a class I’m teaching
A better horizontal axis label would help identify patterns. Looks like some seasonal waves each year – more trips in the summers?
Consistent gas supplier/brand? Do you avoid filling up when your station refills their tanks?
My classic (1996) minis service history (red line is when I bought it)
