94. Diesel
Diesel is a liquid fuel used in compression-ignition engines. Unlike petrol engines, diesel engines ignite the fuel through the heat produced by compressing air rather than by using spark plugs.
Diesel fuels can contain renewable components such as biodiesel. Drivers should always use a diesel grade that is approved by the vehicle manufacturer, as using an incompatible fuel can damage the engine or fuel system.

Can every diesel vehicle use every type of diesel?
No. Compatibility depends on the vehicle and engine. Drivers should follow the manufacturer's specifications before using fuels such as B10, higher biodiesel blends or synthetic diesel.
