Fuel & Your Ford

Understanding Fuel Economy

How is fuel economy measured?
Legislators in automotive producing regions around the world have worked with the automotive industry to develop standard tests to measure the fuel economy of all vehicles sold in their local markets. The tests have been created to reflect actual driving conditions so that consumers have realistic and comparable data they can use to assist them in their purchase decisions.

Vehicles are driven through a controlled series of 'drive cycles' set out in the regions standards to obtain an average fuel consumption figure recorded from the drive cycles.

The standards require the 'drive cycles' to follow specified speeds and gear rations for a defined duration. The drive cycles represent typical kinds of use for the region, such as stop-start urban conditions and higher speed motorway driving.

Is there a standardised global fuel economy test?
No. Fuel economy tests have been developed independently in different regions over the past 30 years, reflecting the different driving conditions and vehicle types in each market.

In New Zealand, there is not a standard regional fuel economy test. Because of this, Ford New Zealand uses the fuel economy tests from the region the vehicle has been manufactured in.

Are the results from the different test methods comparable?
No. While given test methods will provide a general indication of a vehicle's likely fuel economy, making direct comparisons between vehicles using data from different regions will be misleading.

Comparisons are misleading because:

  • Vehicle specifications and calibrations differ between markets to suit local regulations and customer requirements
  • Government fuel economy testing methods are different and test results will vary according to the method used.

Please always check the testing method when comparing the fuel economy of the vehicles

Why is real-world fuel economy often different from the published figures?
'Official' figures are based on standardised tests developed to provide customers with reliable information to make comparisons between vehicles. While the tests are designed to reflect real-world conditions, they cannot account for the wide variety of factors which can have a significant effect on fuel economy such as individual driving style, traffic and road conditions, and vehicle load. These factors, along with weather conditions and the use of features like air conditioning, mean that real-world fuel consumption may deviate from the published figures.

Ethanol Compatibility

Will my vehicle run on ethanol-blended petrol?
Ford New Zealand's current petrol range is compatible with E10 fuel.

Make Model E5 Suitable E10 Suitable
Ford Focus (2002 - 2004), F-series (1986-1992), Ka (All),
Mondeo 2.5l (pre-2001),Transit (1996 - 2004)
Yes No
Ford Capri (All), Courier 2.0L & 2.6L (All), Econovan (pre-2002),
Festiva (All), Laser 1.3L, 1.5L & 1.6L (All), Telstar (All)
Sierra (All), Escort (All)
No No
Ford All models post 1986 except above Yes Yes

Please note that no Ford vehicles prior to 1986 are compliant.

Can I use a higher blend than recommended?
We strongly advise that you only use the blend recommended in the table above.

Will ethanol fuel affect my fuel consumption?
Yes. As ethanol produces less energy then traditional fossil fuels, more fuel is required to run the engine. A general rule is your fuel consumption will increase around 3% with an E10 blend.

Biodiesel Compatibility

Will my vehicle run on biodiesels?
New diesel Fords in New Zealand will operate on diesel fuel that contains up to 5% Biodiesel (B5) that meets the specification defined by EN 590, or equivalent.

All vehicles manufactured from 2005 are B5 compatible.

Things to be aware of before filling your vehicle with B5 fuel are:

  • Never use fuel other then specification EN590 or the equivalent for your vehicle. Use of petrol or paraffin in diesel engines will result in engine damage.
  • Never use such fuel with more than 5% concentration of biodiesel in your engine. Use of such fuel could cause low engine performance or serious engine damage.
  • Never add fuel system additives or cleaning agents. These may cause damage to the system.
