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, vehicles running on Autogas use approximately 30 percent more fuel than petrol-powered equivalents. Remember, however, that this is more than offset by the much lower cost of Autogas, which is typically half the price or less than unleaded petrol.

Autogas systems fitted by an installer after new vehicle purchase are generally warranted by the installer. Your insurance company should be informed of the modification to Autogas, and you should ask them to revise the sum insured to reflect the replacement cost of the Autogas system

Autogas reduces engine wear, enhancing the reliability of LPG-powered motor vehicles.
