$9 each or all for $96 BG, part #110 BG MOA is the number one motor oil supplement, chosen 8:1 over the next aftermarket supplier. Engines run at higher temperatures combined with the increasing regularity of stop-and-go driving, creating rapid depletion of critical oil additives. Without protective additives, severe oxidation of the engine oil can occur, reducing the oil to heavy black sludge in the crankcase, oil screens, oil passages, rocker arms and other critical areas of the engine. BG MOA strengthens all qualities of motor oil, providing long-lasting superior engine protection and maintaining peak engine performance. Prevents oxidation and thickening of engine oil even under the most intense driving conditions. Warning: This product can expose you to chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
