Methodology: Calculations based on EPA-certified emissions factors for diesel and propane. Fuel economy equivalency uses the established propane energy density ratio (5/3 gal LPG per gal diesel). DEF cost estimated at $0.20/gallon diesel. Emissions: diesel CO₂ 10,459 g/gal; propane CO₂ 5,792 g/gal; diesel NOx 5.756 g/gal; propane NOx 0.105 g/gal; diesel PM 0.111 g/gal; propane PM 0.032 g/gal. Results are estimates and assume standard urban/highway routes with modern Class 5–8 vehicles.

How We Calculate

Transparent, EPA-Based Methodology

Every figure in this calculator is derived from publicly available EPA emissions factors and real-world fleet data.

1

Fuel Volume

Total diesel gallons = fleet size × days × miles ÷ MPG. Propane gallons = diesel gallons × 1.667 (energy equivalency ratio).

2

Cost Comparison

Diesel cost includes both fuel and DEF fluid ($0.20/gal). Propane requires no DEF, no DPF, and no regen cycles.

3

Emissions Analysis

CO₂, NOx, and PM values computed from EPA g/gal emission factors then converted to pounds via unit conversion.

Why Propane

Performance Without Compromise

No DEF. No DPF. No regen cycles. Just lower cost and cleaner combustion, available with existing infrastructure today.

$0

DEF Required

Eliminate diesel exhaust fluid entirely. No more DEF tanks, sensors, or injector maintenance.

97%

NOx Reduction

Propane combustion produces dramatically less nitrogen oxide than diesel — no SCR system needed.

30%+

Lower TCO

Reduced fuel cost, fewer fluid expenses, and lower maintenance burden add up quickly at fleet scale.

Now

Ready Today

No new infrastructure required. Propane fueling stations are already widely available across the U.S.
