Engine performance is a concern in the modern lubricant market. Another factor playing a significant role in this is the TBN (Total Base Number) booster additives incorporated into engine oils. This is intended to ensure that the engines are not affected by the acidic byproducts generated during combustion. TBN booster additives neutralize acids, prevent corrosion, and extend oil lifespan by raising its alkalinity. For lubricant producers, industrial purchasers, and engine oil formulators, selecting high-quality TBN booster additives is critical to delivering high-quality engine protection and performance.
Chempol offers TBN booster additives that meet the requirements of engine oil manufacturers worldwide. These additives provide reliable protection, even in demanding operating environments. The following provides an overview of the role of TBN booster additives and the capabilities Chempol offers for bulk procurement.

TBN booster additives are chemicals added to engine oils to increase their TBN (total base number). TBN (Total Base Number) indicates how well oil neutralizes acids produced when an engine runs. Combustion, especially in diesel and heavy-duty engines, creates acidic byproducts that can lead to corrosion, wear, and sludge. TBN booster additives enhance the oil's acid-neutralizing capacity, providing longer-lasting protection for engine parts.
TBN measures how well engine oil can neutralize acids. As oil is used, its TBN decreases, making it less effective at protecting against acids. This can cause engine wear and shorten oil lifespan. TBN booster additives help keep oil alkaline, allowing it to keep protecting the engine efficiently over time. TBN is an important part in detergents.
TBN booster additives enhance the performance of oil in the following ways:
They help neutralize acids formed during combustion, preventing corrosion and wear.
By maintaining a stable TBN, these additives protect vital engine components from acid buildup-related damage.
With enhanced acid-neutralizing capacity, the oil will last longer, leading to fewer oil changes and lower maintenance costs.
Engine oils are subjected to severe conditions, especially in diesel and heavy-duty engines, where combustion byproducts, such as sulfur and nitrogen compounds, can form acids. A lack of adequate alkalinity means the engine oil is unable to counter the effects of such acids, and corrosion, rust, and other forms of damage can result. TBN high-performance boosters are essential for maintaining engine health and enhancing performance.
Sulfur and nitrogen in the fuel also form sulfuric and nitric acids during combustion, which gradually reduce the oil's pH. These acids may cause serious damage to engine parts unless they are controlled.
Combustion byproducts are usually high in acidic compounds, which degrade the oil's performance. With the help of TBN boosters, these acids are neutralized, protecting the engine from harmful effects.
TBN booster additives provide anti-corrosion protection. TBN boosters protect engine components against rust, corrosion, and wear caused by harmful acids, and help extend engine life.

TBN booster additives come in various types with different properties to suit different lubrication requirements. Here are the major types:
Calcium-based additives are used for their ability to neutralize acids produced during engine operation. Their detergency effect refers to their capacity to help keep engine surfaces clean, reducing sludge and deposit formation. Calcium TBN (Total Base Number) boosters are particularly suited to diesel engine oils, since these engines tend to produce more soot and contaminants than gasoline engines.
Magnesium TBN boosters neutralize acids more effectively than calcium additives because they offer a higher total base number (TBN). These boosters are most commonly used in marine engine oils and other heavy-duty oils that require enhanced resistance to acid-driven corrosion.

Over-based calcium sulfonate TBN Boosters neutralize acidic compounds that form in oils at high temperatures. These compounds can harm engine parts, so over-based calcium sulfonate additives are commonly included in heavy-duty oils for trucks, buses, and industrial machines to offer protection in harsh conditions. We encourage you to consider our Chempol 5540C for these applications.
The TBN booster additives are used across numerous industries to provide the best protection for engines. The most frequently used applications are as follows:
Diesel engines make more acidic byproducts than other engines. TBN booster additives are therefore critical in ensuring diesel engine oil performs well and protects the engine for longer periods.
Marine engines operate in harsh conditions, and they require TBN booster additives to counteract the corrosive effects of sulfuric compounds and saltwater in the fuel.
The construction, agricultural, and transportation industries use heavy-duty engines that require TBN boosters to neutralize acids and maintain engine efficiency even under extreme stress.
Industrial lubricants also include TBN booster additives for machinery that runs at high temperatures to ensure smooth operation and reduce maintenance costs.
In locomotive engines and railroads, TBN booster additives can be used to counter the corrosive nature of the high-pressure combustion and keep the engine operating efficiently.
