This is the only Android app that considers so many factors.
The end result is a very accurate calculation.
Apart from the usual variables as:
- the price of gasoline,
- price of LPG,
- the cost of installation,
The application also includes the calculation:
- increase in the price of the vehicle reviewing the assumed LPG
- increased use of spark plugs
- if there is an increased burning car on LPG
- filter costs and a volatile liquid phase
- review of the potential costs of LPG
... and many others.
