What's dual-fuel?

What does dual-fuel mean, and how is it used?

Dual-fuel refers to cars that can run on both petrol and LPG. They have independent fuel systems, and the driver can switch from one system to another as needed. The advantages are that LPG is cheaper than petrol, so your running costs are lower, and the range of your car is extended because you have two tanks of fuel, one petrol and one LPG, allowing you to drive further between refills.
