How the fuel saver works
Available From :-



Save money and the environment as you drive.

Dyno Testing has confirmed the performance improvement, as stated, which ultimately improves the fuel consumption.

In straight forward terms you do not have to push down on the accelerator as hard, to achieve the same performance, after the Obst Design Fuel Saver is fitted.

The environmentally friendly fuel saver is fitted onto the engine after the air mass metre. We have organized motor mechanics to fit the device at their service centre.


The engine does not have to be adjusted. The air/fuel ratio remains the same. While the cost of fitting the fuel saver is included in the purchase price. Which you will recoup with fuel savings of between 10 -30 %. (Based on feedback from  customers using the Obst Design Fuel Saver over the last two years)

The device rotates the air as it enters the engine resulting more complete combustion which decreases fuel consumption and emissions. It also improved the pulling power and the throttle response. Manual vehicles are capable of pulling up hills one gear higher, while automatic transmission vehicles change down less frequently under load to a lower gear, without laboring the engine. The engine is more flexable which saves gear changing in the hills and around the city with no harm to the engine. The Obst Design Fuel Saver does not have any moving parts and does not move itself.

The device is manufactured from (2 mm. for cars and 2.5 mm. for trucks) galvanized steel and CNC plasma profiled to the required size to suit your vehicle.

The Obst Design Fuel Saver is suitable for vehicles manufactured after the year 2000.  EFI, diesel or gas engines that are normally aspirated, turbo or supercharged.

Price :-  Approximately $150 - $250 Cars  $250 - $350 Trucks depending on model.

Why should people be concerned about fuel consumption?
Cars are not cheap to run. The less fuel you use, the more money in your pocket. Transport accounts for around 44% of Australia’s energy use (with passenger transport making up 57% of that) and 40% of its carbon dioxide (CO2) emissions, and it’s growing fast. There isn’t an endless supply of fossil fuels. Also, the more fuel efficient your vehicle is, the less carbon dioxide it produces. Carbon dioxide is the main greenhouse gas contributing to climate change. It makes financial and environmental sense to own a fuel efficient vehicle, maintain it and drive it well.

9 STEPS TO EFFICIENT DRIVING

1. Ensure your car is tuned and serviced regularly.

2. Reduce your speed. Driving More slowly reduces fuel consumption.

3. Travel lightly and remove Unnecessary items from your car to reduce weight and improve aerodynamics.

4. Consider how much you use your air conditioner - it can use up to 10 per cent extra fuel.

5. Make sure your tyres are inflated to the correct pressure.

6. Avoid peak hour.

7. If you have a manual transmission, fuel economy typically improves when shifts occur at lower speeds.

8. Filling up past the first click of the fuel nozzle means that fuel can be lost through the overflow pipe when you accelerate or go around corners.

9. Drive smoothly, harsh acceleration and braking can use up to 30 per cent more fuel.

Driving Style

Using the brake, accelerating quickly and overloading your car all contribute towards lower gas mileage. Try to drive as smoothly as you can from point to point, using your brake only when necessary. Think ahead – not only is it safer – but your passengers will thank you for the smoother ride.

Checking Fuel Consumption

Before fitting the Obst Design Fuel Saver you should check your current fuel consumption by the trip meter reading and actual fuel used. Many late model cars have a computer readout but this should be checked for accuracy.

Follow these steps.

1. Zero the trip meter and fill the tank to the first click on the petrol bowser nozzle.

2. Use half of a tank of fuel or more on a regular trip. Carrying extra passengers, accelerating harder and towing will alter the result.

3. Make a note of the trip meter reading at the time you refill the tank, up to the first click on the petrol bowser nozzle.

4. Divide the trip meter reading by 100. (250 Kilometers it becomes 2.5.)

5. Divide the fuel used by the above figure obtained. (If you used 30 litres of petrol divided this by 2.5 and the fuel consumption is 12 litres per 100 kilometers)
