New Gasoline with 35% Ethanol Raises Concern in Brazil Because It Can Cause Damage to Engines, Just Like the Addition of More Biodiesel to Diesel
Experts warn about the potential impacts on engines and vehicle emissions resulting from the significant change in the percentages of ethanol in gasoline sold in Brazil. The Bill 4516/2023, proposed by Deputy Arnaldo Jardim (Cidadania-SP) and approved in the Chamber of Deputies, raises concerns among industry experts about the possible damage to car engines.
The proposal, which has sparked intense debates, suggests significant changes to the levels of ethanol in gasoline and biodiesel in diesel by the year 2030.
35% Alcohol in Gasoline – How Will Engines Behave? Carburetor and Injection.
The approval of the project raises concerns about the possible effects on engines and vehicle emissions. Experts warn that, although flex-fuel cars are designed for any mixture of gasoline and ethanol, vehicles powered exclusively by gasoline, especially older or imported ones, may face challenges and suffer engine damage.

Increase in Ethanol Content in Gasoline May Result in Increased Fuel Consumption in These Vehicles
Rogério Gonçalves, director of fuels at the Brazilian Automotive Engineering Association (AEA), highlights that the increase in ethanol content in gasoline may lead to higher fuel consumption in these vehicles. Additionally, more sensitive engines may require new calibrations and adjustments to ensure proper functioning.
The use of premium gasoline, with higher octane and lower ethanol content, emerges as a viable alternative for vehicles more sensitive to changes.
New Percentages of Ethanol and Biodiesel in Diesel
Currently, regular gasoline contains an anhydrous ethanol percentage of 27.5%, with a minimum requirement of 18%. With the approved bill, the proposed values change, establishing a minimum of 22% and a maximum of 35% for the addition of ethanol to gasoline.
In diesel oil, the added biodiesel is currently 14%, which may increase up to a limit of 20% by March 2030.
