Plug Fuelix into your vehicle’s OBD2 port, usually located under the dashboard near the steering wheel. Once connected, simply drive as normal. No tools, wiring, app setup, or mechanic visit required.

2. Will Fuelix work with my car? +

Fuelix is designed for most OBD2-compatible vehicles. Most U.S. cars made from 1996 onward and many EU cars from 2001 onward have an OBD2 port. We recommend checking your vehicle has an OBD2 port before ordering.

3. Do I need a mechanic to install it? +

No. Fuelix is made for simple DIY setup. Just locate your OBD2 port, plug it in, and you’re ready to drive. There’s no wiring, cutting, programming, or workshop visit needed.

4. Can I move Fuelix between cars? +

Yes. Fuelix is compact and removable, so you can unplug it and use it with another compatible vehicle. This makes it a good option for households with more than one car.

5. Will Fuelix drain my battery? +

Fuelix is designed to be used while your vehicle is running. For best results, plug it in before driving and remove it if your car will be parked for an extended period.
