To calculate how much you'll save in fuel*, enter the number of vehicles in your fleet, the average kilometres you drive annually per vehicle, and the petrol and LPG prices you think are most appropriate (we recommend using average prices from a reasonable period of time such as one year rather than current actual prices). The default petrol** and LPG*** prices in the calculator come from the current price section of the table below. You can modify the price and other fields in the calculator to suit your specific vehicle or driving style, such as fuel consumption per 100km usage****

* Savings shown are approximate and will vary according to fuel and petrol discounts available to fleet operators, fuel consumption of individual vehicles, driving style and road conditions.

** Based on current MED weekly average retail price for 91 petrol - see table below. MED data comes from www.med.govt.nz/templates/Page____38622.aspx

*** Based on current Rockgas Fuelcard price for a 500 litre plus discount at red dot sites – see table below. Fuelcard prices rather than retail pump prices are used as the Fuelcard is available to the general public with no minimum usage requirements although credit requirements do apply. If you do not qualify for the 500 litre plus rate it is unlikely that converting to LPG will offer any financial savings.

**** Fuel consumption figures are based on AS2877 tests for Falcon Forté 6-cylinder auto sedan, which indicate that an LPG vehicle will use 28.6% more fuel than a petrol vehicle to travel the same distance.

By using a Rockgas Fuelcard to purchase automotive LPG the price you pay is determined by your pricing plan with Rockgas and not linked to the retail price shown on the LPG dispenser. Fuelcard prices are lower than the recommended retail prices for automotive LPG at Rockgas supplied Service Stations
