What ECO Fuel Is

ECO Fuel is a small plug-in device that connects to your car's OBD2 diagnostic port — the same port a mechanic uses to read fault codes. It requires no wiring, no tools and no workshop visit. According to the manufacturer, once fitted it reads how you drive over roughly the first 150 miles and then works with the engine control unit (ECU) with the aim of improving fuel efficiency.

Key points before you buy

  • Check your port first: most petrol cars sold in the US from 1996, and in the EU from 2001, have an OBD2 port. Confirm yours does before ordering.
  • Reversible: the manufacturer states the device makes no permanent changes to the ECU, and that unplugging it returns the car to its original settings.
  • Results vary: fuel consumption depends on the vehicle, its state of maintenance, tyre pressure, load, driving style, traffic and terrain. This site promises no specific level of saving.
  • Ask for substantiation: where the retailer advertises a percentage figure, ask what testing it is based on before you order.
  • Check your warranty and insurance: before fitting any aftermarket device, confirm the effect on your manufacturer's warranty and your cover.

* Pricing, stock, shipping times and guarantee terms are set by the retailer and shown on their checkout page. Confirm them there before ordering.
