Calculate

- Diesel and gasoline prices captured and averaged from EIA.gov (The U.S. Energy Information Administration).
- Miles per gallon figured for gasoline, diesel and propane vehicles are estimates only and variations will occur.
- Propane autogas fuel price is an estimate and is subject to change based on location, fleet size and contract terms.
- The Texas Railroad Commission sites a 50% reduction in maintenance costs by running a vehicle on propane compared to gasoline.
