Bio-based gasoline grades available
Portugal’s Decree-Law No. Annex III indicates the quality requirements for gasoline, and allows the sale of gasoline grade RON 95 with ethanol content at 5% v/v maximum and RON 98 at 10% v/v maximum.
However, E10 has not yet being implemented in Portugal, therefore two grades are available: RON 95 E5 and RON 98 E5.
