How are Brazillian N54s holding up to the 20% ethanol fuel
People in the US are interested in adding even more ethanol to gas to make, perhaps E20, 20% ethanol and 80% gasoline. Apparently Brazil has been using this gas for many years. I am curious if there are any N54 owners in Brazil who can comment on their experience. Did you have any mechanical problems with your cars because of the higher ethanol amount? Are cars in Brazil modified in some way to handle the 20% ethanol fuel? Thanks.
