High Aluminium + Silicon (Catfines) Levels in Fuels from Singapore

Recently FOBAS tested several residual fuel samples from Singapore, that exceeded the 60 mg/kg limit, for Aluminium + Silicon as stipulated in the ISO 8217:2010/12/17 specification. The fuels tested had values of these catfines, ranging between 74 to 97 mg/kg.

Al+Si content at these concentrations may not readily reduce to acceptable levels (< 15 mg/kg at the engine inlet) by means of normal onboard treatment.

Please find attached a bulletin which provides further information in relation to this.
