final result in accordance with EN 228:2008. 4 The fuel may contain oxidation inhibitors and metal deactivators normally used to stabilise refinery gasoline streams, but detergent/dispersive additives and solvent oils shall not be added. 5 Ethanol meeting the specification of EN 15376 is the only oxygenate that shall be intentionally added to the reference fuel. 6 The actual sulphur content of the fuel used for the Type 1 test shall be reported. 7 There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel. 8 The ethanol content and corresponding oxygen content may be zero for engines of category SMB at the choice of the manufacturer. In this case all testing of the engine family, or engine type where no family exists, shall be conducted using petrol with zero ethanol content. 2.2.

Therefore, the addition of such compounds for the sole purpose of biasing the test method is prohibited. 3 At the request of the engine manufacturer, a higher MON could be used to perform the type approval tests. 3.2.
