Thank you for your decision to become an eFlexFuel driver. By choosing ethanol fuel you will significantly reduce your emissions.
eFlexFuel has been installed to thousands of different vehicles and our customers drive over 7M miles with the device each month. Furthermore, the E85 ethanol fuel contains additives that make its lubrication and corrosion prevention features on par with regular gasoline. Therefore, you can trust that you can use E85 fuel in your vehicle safely.
eFlexFuel operates completely automatically and after installation it does not required any attention from the user. However, to ensure the optimal functionality of the device the vehicle should be maintained and in normal working condition. In this guide we will briefly tell about using eFlexFuel and ethanol fuel to ensure that you have the best possible driving experience no matter which fuel you use.
When driving with eFlexFuel and ethanol fuel you can still follow the regular maintenance schedule recommended by the manufacturer of your vehicle. We recommend ensuring that the following components especially are in normal working condition:
Please note that besides the mileage and the age of the vehicle the driving circumstances and the way the vehicle is driven has a great impact on the durability and maintenance needs. For instance, if the vehicle is driven for only short distances in cold weather the maintenance intervals should be shorter no matter what fuel is used.
eFlexFuel has been designed, tested and manufactured in one of the coldest countries in the world, Finland. Thus, a lot of emphasis has been put into ensuring that the device and the vehicle will work also in extreme cold. eFlexFuel vehicle will start even in the coldest temperatures. But in the most extreme conditions with pure E85 fuel it might require couple of starts. We highly recommend using an engine heater whenever it is possible.
If the vehicle is properly maintained it can be driven with E85 fuel around the year. If cold starts are sluggish, we recommend adding up to 10% of regular gasoline in the tank. This can be done by for example filling up with 3 gallons of regular in every other fill up.
eFlexFuel enables using both regular gasoline and ethanol (E85) or any mix of these two in the vehicle. We highly recommend using fuel with as high ethanol content as possible (E85) but if it is not available the vehicle will still work perfectly on regular gasoline as well. When E85 is used the consumption of the vehicle compared to regular gasoline is increased by approximately 28% depending on the vehicle. Please note that the onboard computer of the vehicle does not recognize this change.
eFlexFuel App shows the ethanol content of the fuel or the injector duty cycle. eFlexFuel App can be downloaded for free from Google Play store or from iOS App Store. More information about the app can be found here.
