New synthetic petrol engine oil reduces car exhaust emissions

Supplier News

MOST of today's petrol engines are fitted with three way catalytic converters, which reduce emissions of CO, NOx and unburned carbon. These converters include a reduction catalyst, which converts NOx to harmless nitrogen, and an oxidation catalyst, which burns the CO and hydrocarbons.

Catalytic converters, however, are susceptible to SAPS (sulphated ash, phosphorous and sulphur) that are present in detergent, anti-wear additives and base oils. High SAPS levels are found in most of today’s petrol engine oils.

Catalytic converters often use metals such as platinum or rhodium, which can be deactivated by phosphorus and sulphur and cause irreversible damage that accumulates over time. Contaminants then pass untreated through the engine and enter the atmosphere.

Till now, there were no limits on the levels of SAPS found in petrol engine oils.

AnglomOil has released the RoadMaster 500 Petrol Engine Oil, a fully synthetic lubricant conforming to the American Petroleum Institutes latest petrol engine oil specification, SM.

The SM petrol engine oil specification includes many tough demands including better wear protection and demands of a longer oil life to reduce oil consumption, which will help extend the life of the world’s oil reserves.

The demands are so tough that standard mineral base oils cannot meet them, only synthetic petrol engine base oils can be used, according to AnglomOil.

AnglomOil’s RoadMaster 500 fully-synthetic SM petrol engine oil is available in a viscosity of 10W-40 and meets the API SM petrol engine oil specification.

The RoadMaster 500 is good for the engine and good for the environment, says AnglomOil.
