The Science Behind Low-Emission Engine Oils

Published by: Chevron Technology | 20-Mar-2025

As the automotive industry increasingly prioritises sustainable and greener transport solutions, the role of low-emission engine oils becomes crucial to attaining these goals. With emission standards becoming stricter, these engine oils contribute to better engine performance, increasing overall fuel efficiency and helping create a greener environment. These advanced lubrication solutions are specifically designed to complement modern emission-reducing technologies used in modern engines.  

Traditional mineral-based high SAPS (Sulfated Ash, Phosphorus, and Sulfur) engine oils might not be suitable for modern engines as they often hinder the performance of advanced emission-control systems such as catalytic converters and diesel particulate filters (DPFs). Low-emission engine oils, however, are specially formulated to work in tandem with these systems, ensuring that minimal harmful deposits are formed in the engine and that it runs cleanly and efficiently, thus contributing to reducing toxic emissions. 

The technology behind low-emission engine oils 

Low emission engine oils are made using advanced formulations designed to reduce the buildup of harmful deposits inside the engine. They are engineered to support the smooth operation of sophisticated exhaust after-treatment systems, which are mandatory for vehicles under the latest and stricter emission standards like BS6. The core of these lubricants is formed using a combination of high-quality synthetic base oils and advanced additives technology. 

The key properties of these engine oils include the reduction of engine friction, leading to lower fuel consumption and reduced emissions. Further, these oils improve engine performance, reducing the strain on emission-control systems. Overall, these lubricants help maintain an optimal balance between engine protection and fuel economy. 

Choosing the right low-emission engine oil 

A great example of low-emission synthetic engine oil is the Caltex Havoline Fully Synthetic LE 5W-30, which is engineered using Chevron's (the parent company of Caltex) patented Deposit Shield technology. This minimises the risk of sludge and carbon buildup inside the engine, providing superior protection for modern engines and emission-control systems used in them. This high-performance lubricant ensures the optimum functioning of catalytic converters and diesel particulate filters, significantly enhancing the environmental benefits of modern-day vehicles. Further, the Havoline engine oil is suitable for use across various automotive platforms, including Indian, European and Japanese vehicles. 

The Havoline Fully Synthetic LE 5W-30 also enables longer oil change intervals, which reduces the need for frequent oil changes. With extended oil change intervals, maintenance costs also get significantly lowered for vehicle owners, making them a more sustainable option. Thus, it is the top choice for environmentally-conscious petrol or diesel vehicle owners.  

Why does Havoline Fully Synthetic LE 5W-30 engine oil stand out? 

This Havoline engine oil has been formulated to meet the requirements of the modern engines that use emission-control systems to meet regulatory standards. The engine oil offers exceptional protection against engine wear and tear, increases engine durability, reduces friction and minimizes sludge formation. It fully optimises engine performance while supporting cleaner emissions.  

This low-emission engine oil is manufactured locally in India in partnership with Hindustan Petroleum Corporation Limited (HPCL) while meeting international quality standards. It is a part of the strategic partnership between Caltex and HPCL to manufacture and distribute engine oils that cater to the evolving industry requirements. The product will be available across the country through authorised automotive lubricant retailers, authorised service centers, and through official distribution channels. 

The Havoline Fully Synthetic LE 5W-30 is a vital product for the Indian automotive industry as it shifts towards sustainability and greener emissions. This engine oil offers comprehensive vehicle performance and protection. Engine oils like this exemplify the future of lubrication technology as we move towards a more sustainable future.
