ACDelco Gold Automotive AGM Batteries
ACDelco Gold Automotive AGM batteries have high-cycling capabilities, are remarkably charge-receptive, and are necessary for start/stop applications. These batteries are also maintenance-free, 100 percent pressure-tested against leaks, and are manufactured to resist corrosion. Best of all, they are backed by ACDelco's outstanding warranty coverage. When reliable starting power is a priority— ACDelco Gold Automotive AGM batteries are the answer! Additional features include: * Absorbed Glass Mat design is 100 percent leak and spill-proof, because the electrolyte is permanently held in the glass mat separator, instead of free flowing within each cell * Oxygen recombination reduces water loss and reassures maintenance-free performance * ACDelco Gold Automotive AGM batteries have longer life expectancy in traditional vehicle applications, due to a maintained pressure on the plates, which significantly reduces the amount of active mass lost from the grid

Royal Purple Premium High Performance Motor Oil
Royal Purple Premium High Performance motor oil combines premium synthetic base oils with proprietary additive technologies to exceed protection and performance requirements of new modern engines. These often include smaller displacements, turbo chargers, gasoline direct injection (GDI), and start/stop systems. Modern gasoline direct injection (GDI) engines have achieved levels of power and fuel economy never before possible in passenger car engines. As a result, smaller engines operate at much higher loads across all engine speeds. This has caused increased wear in critical areas of the engine, and created a destructive phenomenon called low-speed pre-ignition (LSPI). The unique, state-of-the-art additive technology in Royal Purple High Performance engine oils is designed specifically to address these issues, and help engines maintain performance and reliability.
