Modern LPG Autogas engine technology provides performance and fuel economy comparable with contemporary petrol-powered engines. On Autogas, torque is available at lower engine revs, which aids driveability – particularly in stop/start city driving. In some cases total torque is actually increased.
The power output of engines with Electronic Fuel Injection (EFI) is, when converted to run on Autogas, usually only slightly lower than on petrol. Where possible, the Autogas system is interfaced with the original EFI computer. While top speed may be marginally reduced and acceleration times cut by fractions of a second, most drivers would be unlikely to detect the difference.
The fuel economy of Autogas-powered vehicles depends on a range of factors but on average, late model vehicles running on Autogas use approximately 30 percent more fuel than petrol-powered equivalents. However, some high consumption petrol vehicles may in fact use only 20 percent more autogas.
Remember, however, that this is more than offset by the much lower cost of Autogas, which is typically half the price or less of unleaded petrol. The introduction of improved performance Autogas injection systems will see this 30 percent figure reduced even further.
Most vehicles will run effectively on Autogas but you must ensure that the equipment installed is suitable for your vehicle. New vehicles that are fitted with Autogas systems adhere to strict guidelines and any conversions should only be performed by a licensed installer.
You can enjoy the performance and low running costs of an Autogas engine system secure in the knowledge that Australian standards governing the safety of such systems is the most stringent in the world
