I’ve never been confident with technical stuff, but installing this little device was really simple. It only took a few minutes, and everything worked perfectly. After a week, I noticed that my fuel consumption had actually decreased. I highly recommend it to anyone who doesn’t want to pay a fortune for diagnostics at a car service.

As a family, we drive daily to school, activities, and shopping… Fuel is a major expense, but ever since we got this fuel saver, we refuel less often. On our Škoda Karoq, we reduced fuel consumption from 7.4L to 6.1L per 100 km. We’ve truly saved money—thank you!

I have a 2008 Peugeot 307 and always thought that reducing fuel consumption in an older car was impossible. But FuelSpar proved me wrong! The car runs more smoothly, and my fuel consumption dropped from 8.3L to 7L per 100 km. If you have an older car, it’s definitely worth a try!

I’ve tried various ways to reduce fuel consumption—premium fuel, fuel additives—but nothing had the same effect as FuelSpar. On my Opel Astra, fuel consumption dropped to 5.3L/100km without any other changes. Finally, something that actually works!

Verified Customer
I often drive long distances and have been looking for a way to save on diesel for a while. Before my last trip, I installed FuelSpar, and I was amazed! My average fuel consumption from Bratislava to Košice dropped from 6.8L to 5.5L per 100 km. It really pays off on long journeys! 👍

I’m a taxi driver, and every extra liter of fuel means less profit. I bought FuelSpar out of curiosity, but now I recommend it to my colleagues. My Toyota Prius used to consume 5.1L/100km, and now it’s down to 4.2L. With my mileage, I save dozens of euros every month!

Yes, FuelSpar works in all cars equipped with OBD2 port (all manufactured after 2001).
