Gasoline combustion in an engine always produce carbon particle which then agglomerate, precipitate, and degrade the engine performance. In this research PIB amine, a surfactant having PIB as the hydrocarbon nonpolar tail and TEPA as polar head, is prepared and tested as deposit controlling agent (DCA) f or gasoline. This reaction product is a viscous liquid with density 0,8566 g/ml and kinematic viscosity @40°C of 75,16 cSt, and on its FTIR spectrum shows peak at 3200-3500 cm-1 (amine group). Its anti-deposit performance has been tested using single cylinder gasoline engine, at concentration 300 ppm PIB amine can significantly reduce deposit, comparable to that of the commercial PIBA. The 300 ppm PIB Amine gasoline is also pass gum test, with unwash gum value <75mg/100mL and wash gum value <5 mg/100mL.
