EcoPlug - OBD2 Fuel Reducer
EcoPlug - OBD2 Fuel Reducer
Fuel prices have reached a level that seemed unthinkable two years ago. Super E10 and diesel now cost significantly more than usual at many gas stations. Regular commuters today pay 150 to 300 euros more per month than they did a year ago – for fuel alone.
The ongoing conflict in the Middle East is keeping global crude oil markets under constant pressure. Experts agree: As long as the situation remains tense, prices will stay high – or continue to rise.
What is EcoPlug?
EcoPlug is a compact OBD2 plug, developed in Berlin. The device connects to the engine control unit via the OBD2 port and optimizes in real time:
- Fuel injection
- Ignition timing
- Engine load maps
Manufacturers calibrate these parameters at the factory for a compromise between performance, emissions, and durability – not for maximum fuel efficiency. EcoPlug closes precisely this gap.
Easy to use – no app, no instructions
- Locate the OBD2 port (usually under the dashboard, driver's side)
- Plug in EcoPlug
- Turn on the ignition – green LED lights up
- Wait 5 minutes
The device calibrates itself automatically to your vehicle within the first 150–200 kilometers. After that, it runs continuously in the background.
Compatible with all vehicles from model year 1999 onwards with an OBD2 port – petrol and diesel, all brands (VW, BMW, Mercedes, Audi, Toyota, and many more).
Our test results
We tested EcoPlug on two very different vehicles on identical routes: 100 km highway (130 km/h) and 100 km city driving in Berlin.
VW Golf 4 (2001, petrol, 1.6L, 105 hp)
- Highway: 8.4 L → 4.4 L/100 km (−48 %)
- City: 11.2 L → 5.4 L/100 km (−52 %)
BMW 5 Series (2023, diesel, 2.0L, 190 hp)
- Highway: 6.1 L → 3.4 L/100 km (−44 %)
- City: 8.8 L → 4.7 L/100 km (−47 %)
Particularly impressive: The driving behavior did not change – no loss of performance, no different throttle response. The savings come exclusively from the optimized engine control.
Our conclusion
We approached this test with skepticism. The results proved us wrong.
For an average commuter driving 80 km daily, a saving of 48–52% means a monthly saving of 80–110 euros. EcoPlug thus pays for itself in less than a month.
Our recommendation: Anyone who drives regularly and feels the current fuel prices should try EcoPlug.
❓ Frequently Asked Questions
The most important questions from our customers – answered concisely.
Does EcoPlug also work with my older vehicle?
Yes. EcoPlug is compatible with all vehicles from model year 1999 that have an OBD2 port – this applies to almost every car on German roads, regardless of make or engine type.
Do I have to install or configure anything?
No. Simply plug it in, turn on the ignition, and wait. No app, no software, no settings. The device calibrates itself automatically within the first 150–200 kilometers.
Does EcoPlug change driving behavior or engine performance?
No. In our tests, no change in driving behavior was noticeable. No loss of performance, no different throttle response – just lower consumption.
How quickly does EcoPlug pay for itself?
For an average commuter driving 80 km daily and with a saving of 48–52%, the device pays for itself in less than a month.
Does EcoPlug work for both petrol and diesel vehicles?
Yes. Our tests with a VW Golf 4 (petrol) and a BMW 5 Series (diesel) showed similarly strong savings of 44 to 52 percent in both vehicles.
Can I leave EcoPlug plugged in permanently?
Yes. The device is designed for continuous operation and runs completely in the background after calibration.
