It effectively softens, emulsifies and dissolves even the most stubborn fuel gums that clog piston rings.Engines are operating at higher temperatures than ever before. Combined with prolonged oil change intervals and reduced engine cooling, engine oil is under a lot of stress.Continuous thermal and oxidative breakdown contributes to oil thickening, heat retention and deposit formation. These heavy deposits can impede normal piston-ring function; thus reducing fuel economy, lowering power output, and increasing harmful exhaust emissions and oil consumption.BG EPR®, PN 109:softens and dissolves hard-to-remove deposits from piston ringscleans micro passageways to maintain the critical hydraulic function of components such as valve train actuators and turbochargersrestores fuel economy and powerprevents excessive oil lossProperly sealed combustion chambers improve compression and reduce oil dilution through blow-by.
