The Fuel Angel is a misfuelling prevention device that replaces your existing fuel filler cap.
It uses a precision locking system that only allows the correct fuel nozzle to fit, blocking the wrong one automatically.
No electronics, no maintenance — just 100% mechanical protection.
The Fuel Angel fits the vast majority of modern cars, vans, and SUVs.
