Your own average replaces the EPA laboratory values — never averaged together with them — and the driving-mix setting stops applying, because a figure you measured already contains your own mix.
Notes & official EPA estimate
Official FuelEconomy.gov estimate: $2,650/year — assumes 15,000 miles/year and EPA price assumptions. The figures above use your inputs instead.
Cost per mile vs. its segment (2025 Compact Cars, 27 vehicles, default assumptions)
43% above the segment median — a measured energy-cost difference only.
