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. The FuelEconomy.gov “My MPG” average shared by owners is the same kind of substitution, so only one of the two can apply at a time.
Notes & official EPA estimate
Official FuelEconomy.gov estimate: $3,250/year — assumes 15,000 miles/year and EPA price assumptions. The figures above use your inputs instead.
Cost per mile vs. its segment (2026 Standard Pickup Trucks 4WD, 24 vehicles, default assumptions)
0% above the segment median — a measured energy-cost difference only.
