BG Advanced Formula MOA® is formulated with 100 percent synthetic chemistry to protect engine components and fortify all brands of engine oil over extended oil change intervals. Long drain intervals, 10,000 miles (16,000 km) – some as high as 15,000 miles (25,000 km) – are quickly becoming the norm in owner’s manuals. Unfortunately, longer time between oil changes puts a lot more strain on engine oil. Extended oil change intervals provide a lengthy incubation period for carbon deposits. Even high-quality synthetic oils will degrade eventually. Unless the oil is fortified with enhanced protection against high heat, premature and hard-to-remove deposits will form on many engine components. The potent detergency and antioxidant system in BG Advanced Formula MOA® prevents engine oil degradation and thickening under even the most severe stop-and-go, high temperature driving.
