REDUCES EXHAUST SMOKE CAUSED BY OIL BURNING: Specially formulated to address the issue of excessive exhaust smoke, this oil-soluble additive helps reduce smoke emissions caused by oil burning. It works effectively within the engine to stabilise oil consumption, particularly in older or high-mileage engines, where internal components may be worn or degraded. The additive enhances the oil's behaviour under combustion conditions, allowing it to resist being drawn into the combustion chamber. This results in visibly reduced smoke output, making it ideal for improving emissions control and keeping exhaust systems cleaner for longer periods.
