No. Fuel economy varies by driving habits, road conditions, weather, tire pressure, maintenance, vehicle condition, and other factors. FuelSync is designed as a plug-in driving reminder, not a guaranteed fuel-saving device.

Use one per vehicle. Choose a 2-pack or 3-pack if you have multiple cars in the household.
It plugs into the 12V socket like a small car accessory. Do not use if your socket is damaged or if the device gets hot, smells unusual, or behaves abnormally.
Driving habits, road conditions, traffic, weather, tire pressure, maintenance, vehicle condition, and load weight can all affect fuel economy. Avyroa™ FuelSync is designed as a plug-in vehicle efficiency reminder to help keep fuel-conscious habits top of mind. It is not a replacement for proper vehicle maintenance and does not guarantee specific fuel savings.
