Ethanol vehicles - Can I use an ethanol blend in my petrol car?
We strongly advise against experimenting with E85 mixes in petrol cars not converted, or manufactured as "Flexifuel".
Even is the car starts and runs on a certain ethanol blend there is a great risk that the engine is not getting enough or the proper amount of fuel in all load situations or rpm. (According to other answers on this FAQ.)
As long as going within the lambda regulated area the risk of damage is small using a 10-15% blend, but using a higher percentage and going outside of this area, the risk for engine damages is greatly increased.
Some emissions are also transformed negatively, such as increased NOx levels, which is negative for the environment since it is very acidy and can create health risks.
