BG ATC Plus Automatic Transmission Conditioner is to squeeze the utmost efficiency out of vehicles, many OEMs are relying on 8-, 9- and even 10-speed automatic transmissions. More gears improve engine efficiency and allow smaller, more economical engines to power larger vehicles. Automatic transmission fluid deteriorates much faster and fluid breakdown causes deposit formation on crucial transmission components. This buildup can cause transmission slipping, erratic shifting and sometimes full transmission failure. BG ATC Plus packs a punch for automatic transmission fluid! It is formulated with the latest chemistry technology to handle the intense environment in new higher gear transmissions. Added to transmission fluid, it helps prevent deposit formation and fluid breakdown. In essence, it helps prevent transmission failure. BG EPR Engine Performance Restoration is a powerhouse of an engine cleaner! It effectively softens, emulsifies and dissolves even the most stubborn fuel gums that clog piston rings. Engines are operating at higher temperatures and a prolonged oil change intervals, 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 softens and dissolves hard-to-remove deposits from piston rings, cleans micro passageways to maintain the critical hydraulic function of components such as valve train actuators and turbochargers, restores fuel economy and power and prevents excessive oil loss Properly sealed combustion chambers improve compression and reduce oil dilution through blow-by.
