I never realized how much I strain my eyes when driving in the evening until I tried NachtSight. The lights of oncoming cars don't glow as much with them on, and they make driving much more comfortable.

Oliver L., Verified buyer
"I use my car every day, and FuelSpar has really helped me save on fuel costs. The setup was super simple, and the benefits were almost immediate. I’ll be recommending this to all my friends."
Julia T., Verified buyer
"My 2015 Opel Corsa has always been pretty fuel-efficient, but FuelSpar made it even better! I went from 5.9 liters per 100 km to 4.8. It’s such a simple device, and the savings are real!"
Martin K., Verified buyer
I was hesitant at first, but this device truly works. My fuel efficiency has improved, and I can go further on a single tank. Installation was quick, and I couldn’t be happier with the results.
Adam P., Verified buyer
"FuelSpar has been a great investment. I’ve noticed fewer trips to the gas station, and the savings really add up over time. It’s so easy to install, and I would recommend it to anyone."
Clara S., Verified buyer
"I installed FuelSpar before a road trip in my 2015 Skoda Octavia. My average consumption dropped from 7.2 liters per 100 km to 6.0. I’ve already started saving money on fuel, and I love how easy it was to install. It’s definitely worth the price."
Tomas W., Verified buyer
"I use my 2009 Mercedes Sprinter for deliveries and noticed a big improvement in fuel consumption since installing FuelSpar. My average went from 11.2 liters per 100 km to 9.4. The savings add up quickly when you’re driving all day!"

Frequently asked questions
How does it work?
FuelSave OBD2 funguje na báze zmeny signálu z riadiacej jednotky. Dôsledkom toho sa mení celá mapa vstrekovania pre nízku spotrebu a zníženie emisií. Automaticky rozpozná vaše jazdné návyky a vytvorí novú mapu v riadiacej jednotke pre zníženie spotreby až o 15%.

FuelSave OBD2 works by changing the signal from the control unit. As a result, the entire injection map is changed for low consumption and reduced emissions. It automatically detects your driving habits and creates a new map in the control unit to reduce consumption by up to 15%.
