Every fill is treated as a fill to full, so gallons pumped is what the tank was missing. Left-in-the-tank and range are estimates from the rated capacity, not gauge readings.

MPG per tank

Each dot is one tank. The line is the trailing five-tank average; the dashed line is the median over all 78 tanks. Tanks under four gallons are still plotted but never count as a best or worst tank.

Price per gallon

Total paid divided by gallons pumped, one dot per fill-up.

Temperature and mileage

Each tank against the mean temperature over the days it was driven, at Atlanta. Fitted: -0.3 MPG per 10°F over 78 tanks, r = -0.23. Cold, under 50°F: 31.2 MPG (14 tanks). Mild, 50 to 75°F: 30.4 MPG (43 tanks). Warm, over 75°F: 30.2 MPG (21 tanks). Weather data by Open-Meteo.

Avg MPG and Avg $ per gallon are means over tanks, the way the old spreadsheet summarized a year. Cost per mile and miles per day are ratios of the year's totals. A year with a car change counts only this car's tanks.
