Cleans micro passageways to maintain the critical hydraulic function of components such as valve train actuators and turbochargers
Prevents excessive oil loss
Softens and dissolves hard-to-remove deposits from piston rings
Original testing of BG EPR consisted of performing before and after compression tests with an oil change including BG EPR in between. Compression affects the overall power output and drivability of the engine. Results from multiple vehicles proved that BG 109 did raise compression. The results also showed an improvement on individual cylinders that were showing lower compression than the other cylinders of the same engine.
