A. BG Advanced Formula MOA is an engine-oil fortifier that prevents sludge, stabilises viscosity, reduces wear and enhances fuel economy retention. The 325ml bottle (115) treats a typical 4–6 litre crankcase.
A. Add to the engine oil after an oil change to fortify it: 177ml per 3–4 litres of oil, 325ml per 4–6 litres, or 650ml per 7–10 litres. Can also be added when oil is low to top up between changes.
A. BG MOA fortifies engine oil with friction modifiers, antioxidants and detergents to prevent sludge and varnish, stabilise oil viscosity, keep piston rings free, reduce wear, and resist evaporative oil loss across the full service interval.
A. Yes. BG MOA is formulated to fortify all major brands and grades of engine oil — fully synthetic, semi-synthetic and mineral — without affecting the base oil specification.
A. BG MOA contains friction modifiers designed to enhance fuel economy and fuel economy retention. Improvement depends on engine condition and driving style — most noticeable on engines previously running on un-fortified oil.
A. BG recommends MOA at every oil change as preventive maintenance to keep the new oil performing at its best across the whole service interval. It is not a one-off treatment like BG EPR.
A. BG MOA fortifies fresh oil to prevent deposits forming. BG EPR is a one-off treatment added before an oil change to dissolve existing ring deposits. MOA = maintenance; EPR = restoration.
A. BG advises against overfilling the crankcase. Use the treat rate matched to your engine's oil capacity — 177ml per 3–4L, 325ml per 4–6L, 650ml per 7–10L. Excess fluid level itself causes engine problems.
A. Yes. BG MOA is compatible with modern engine emissions systems including diesel and petrol particulate filters and turbochargers, and protects the micro-passageways these components depend on.
