Driving on E85 Superethanol: All you need to know before filling your bioethanol tank

At a time when the purchasing power of the French and our impact on the environment are questions at the heart of society’s challenges, E85 superethanol is a cleaner fuel and saves some money along the way. If you’re interested in E85, we tell you everything there is to know before filling your tank with this nearly petrol-free fuel.

What is E85 Superethanol?

The so-called superethanol E85 is a fuel that is composed of 65 to 85% bioethanol for 15 to 35% gasoline (unleaded 95To locate bioethanol, it is a green fuel that is made from organic material like rapeseed or corn. In this case, it is sucrose or starch extracted from certain plants then transformed by the effect of fermentation and distillationSucrose is extracted, for example, from sugar cane or beet and starch from wheat or corn.

What is the difference with the SP95-E10 or the SP98-E5?

The letter “E” associated with a number represents the level of ethanol that makes up the fuel. If, for its part, superethanol has a maximum of 85% ethanol as explained above, SP95-E10 therefore contains 10% and SP98-E5, 5%. With a much higher rate of gasoline than d ‘ethanol, SP95-E10 and SP98-E5 can be used on most gasoline cars, unlike E85 Superethanol. In addition, their impact on the environment is proportional to the level of ethanol present in the fuel.

Which vehicles are compatible with E85 bioethanol?

To be able to use E85 superethanol, you need a Flex-Fuel vehicle. The latter is a vehicle that can run indifferently with any kind of gasoline (SP98, SP95, SP95-E10, E85) in the same tank.For example, here is a non-exhaustive list of cars compatible with E85, there are many others. and year after year the list of flex-fuel compatible vehicles grows.

  • Ford Focus 1.6 EcoBoost Flexifuel
  • Dacia E85
  • Logan MCV / Duster / Sandero
  • Ford Flexifuel
  • Focus / C-Max / Mondeo / S-Max / Galaxy
  • Renault Bioethanol eco²
  • Mégane III / Kango II / Scenic III / Laguna III /
  • Clio Rip Curl 1.2 16v75 E85 /
  • Modus and Grand Modus 1.2 16v75 E85
  • Volvo Flexifuel – C30 / S40 / V50 / V70 / S80
  • Citroën – C4 1.6 16v BioFlex Pack
  • Peugeot Bioflex – 308 Bioflex
  • Opel FlexFuel – Insigna
  • SAAB Biopower – 3 / 9.5
  • Jeep grand cherokee
  • Volkswagen Golf Multifuel
  • Volkswagen Golf SW Multifuel
  • Volkswagen Golf Sportsvan Multifuel

Otherwise, it is all the same possible to make your petrol vehicle compatible with superethanol by installing an E85 kit.

How to make your vehicle compatible?

If you do not have a Flex-Fuel vehicle, it is possible to make your petrol vehicle compatible with superethanol by installing an approved E85 box.The box will adjust the volume of fuel to be injected according to the amount of energy required by the engine. It is therefore essential for the engine to function properly. Fitting this type of box can cost several hundred euros, but it will quickly pay off if you drive daily. It also allows you to run on all existing gasoline fuels, such as a Flex-Fuel vehicle, therefore comprising the usual SP95, SP98 and of the coup E85, E95 etc… Here is the list of manufacturers of E85 boxes approved or in the process of being approved that you could install on your car:

  • Bio Motors
  • Flexfuel Company
  • Arm Engineering

Is E85 bioethanol an economical fuel?

It is indeed possible to make some savings by switching to E85 fuel thanks to a specific tax. The latter is indeed less taxed and therefore displays a much lower price at the pump than other fuels., the desire being to reduce dependence on fossil fuels. Is this “the fuel of purchasing power”? Probably. E85 was below 70 cents per liter in July 2018 … we let you make the comparison with the gasoline fuel you usually use.

Superethanol E85: An ecological solution or not?

On paper, Superethanol E85 is presented as an ecological solution due to its hybrid composition, between bioethanol and gasoline. In fact, it effectively reduces CO2 emissions produced by vehicles running on fossil fuels.In 2018, Nicolas Kurtsoglou, manager of the National Union of Agricultural Alcohol Producers (SNPAA) argued that 5% of CO2 emissions were reduced at the exit of the exhaust, but that it rose to 70% on overall fuel production with the CO2 absorbed by crops used to produce it it is also necessary that the cultures used to produce fuel are not at the expense of the production of food for the world.
