Here you can find out which cars are compatible with biofuels

Today, almost all vehicles that run on petrol can run on SP95, which contains up to 10% ethanol (E10). In fact, biofuels are used in the form of additives or as a complement to fossil fuels. However, the same vehicles are not all compatible with E85 superethanol, a fuel containing between 60% and 85% bioethanol. A conversion box can be installed in non-compatible vehicles, even if not all vehicles are suitable for this conversion.

What biofuels and compatible cars are there?

Let’s start with a quick reminder of the different fuels available at the pump. You might find:

  • unleaded 95 (E10), a fuel containing up to 10% ethanol;
  • out E85 or super ethanol which contains between 65 and 85% bioethanol and which is cheaper;
  • Diesel fuel (B7) intended for diesel vehicles;
  • SP95 and SP98 containing a maximum of 5% bioethanol.

As a reminder, bioethanol is obtained by fermenting sugar or starch, found in particular in beets, wheat, sugar cane or corn. Also worth mentioning is ETBE (ethyl tertiary butyl ether), a biofuel made from ethanol and isobutene, which is incorporated into petrol in varying proportions (maximum 22% in SP95-E10). Put simply, vehicles registered before 2000 are not compatible with the SP95-E10. They must continue to feed themselves in SP95 or even partially in SP98. In fact, 90% of petrol vehicles today can run on SP95-E10.

As for super ethanol, it is suitable for flex fuel vehicles (VMC) that can run on all petrol fuels (but blending more than 10% bio ethanol is not recommended). These vehicles have an injection system, engine settings and special provisions that allow cold starting, making them suitable to run on E85 super ethanol. Similarly, gasoline hybrid cars can run on this fuel.

Cars that can be converted to super ethanol

Among the non-compatible cars, some can be converted to super ethanol thanks to a conversion kit. This kit, which costs between 600 and 1,400 euros, turns a conventional petrol engine into a flex-fuel engine. General, The reprogramming units can be installed in all petrol vehicles approved since 2000. Thus, diesel vehicles cannot be equipped, as well as those with a carburetor. Please note that the installation must be carried out by a professional.
