Expand your knowledge on compression
Within the internal combustion engine, the compression ratio, as it’s known, is the piston’s movement as it squeezes the fuel/air mixture in the cylinder. BG Products know that sadly loss of compression over time is inevitable. So it’s a good thing BG’s got a product to restore and maintain peak compression! Adding BG EPR to the engine and letting it tick over for at least 15 minutes restores compression by dissolving the deposits that clog rings and seals.
