BARDAHL ALL-U-NEED! B2 Oil Treatment is engineered for older, higher mileage engines that are burning oil or operating under heavy loads or in extreme high temperature conditions. Using proprietary 'polar attraction' technology, B2 Oil Treatment provides a triple layer of anti-wear and anti-friction protection that extends the effectiveness of the lubricant. By adding a tough lubricating film to metal parts, it will remove deposits, reduce corrosion and restore power. This ALL-U-NEED! solution also provides extra lubrication for city driving and during cold start-ups to minimize wear.
