Petrol, diesel, hybrid and refuelling

Road-life decision workshop

Make one decision at a time. Learn from each result, retry mistakes and keep your completed training report.

Change a control and observe why the result changes. These are simplified teaching models, not measurements for a real vehicle.

Petrol engines typically use spark ignition; diesel engines ignite injected fuel through compressed hot air. Use only the fuel specified on the filler flap and handbook.
Stop the engine, keep ignition sources away and follow station instructions. If you add the wrong fuel, do not start the engine; contact assistance. Do not try to dilute it and drive away.
Hybrid and electric vehicles can move silently. A charging connector is not a fuel nozzle: use the correct approved equipment and never touch damaged high-voltage cables after a crash.

Complete every check correctly to master this lesson. Each applied question explains the consequence of your choice.
