The motorcycle market is still expanding, and increasing demand for high-quality lubricants designed to meet the requirements of modern four-stroke engines under demanding operating conditions continues to grow. Advanced additive technology is needed to create motorcycle oils that offer engine protection, transmission durability, and wet-clutch performance for motorcycle manufacturers, private-label oil brands, and blending companies.
One of the most critical decisions in developing a motorcycle oil is the selection of API SL Engine Oil Additive package. Passenger car lubricants do not have to perform the same functions as four-stroke motorcycle oils, which are typically used in a shared sump and thus must protect the engine, gearbox, and clutch.
Today’s motorcycle oils must have a precisely formulated additive package to ensure the correct balance of detergency, dispersancy, anti-wear properties, oxidation stability, and friction control. Improper selection of additive systems can affect engine cleanliness, gear protection, and clutch operation.
CHEMPOL 66025 from Chempol is a special additive technology product developed for four-stroke motorcycle engine oil formulations. It is designed to support the formulation of four-stroke motorcycle oils targeting API SL/SJ/SG/SF performance levels and their application as JASO MA and MA2 lubricants, assisting lubricant manufacturers in producing high-quality motorcycle oils for various markets.
Chempol offers technical consultation, formulation assistance, product recommendations, samples, and bulk supply solutions for companies seeking a reliable additive supplier.

An API SL Engine Oil Additive Package is a balanced mixture of performance chemicals that enhances the properties of base oils and improves the protection of lubricants. While base oil provides lubrication, additive chemistry delivers the advanced performance needed for modern engines. A complete additive package may include:
Many four-stroke motorcycles use the same oil for engine lubrication, gearbox operation, and wet clutch lubrication, which is why special chemistry is required for motorcycle lubricants.
Motorcycle transmissions are mechanically stressed, unlike auto transmissions, since the gears share the same lubricant environment. Thus, the balance of protection and friction properties in a motorcycle engine oil package is important.
A special API SL Engine Oil Additive Package assists manufacturers in developing lubricants that keep the oil clean, minimize wear, and provide reliable operation during the oil service life.
The 4-stroke motorcycle engine must be capable of running at high RPMs, accelerating rapidly, fitting into small engines, and withstanding high temperatures. Advanced lubricant technology is needed for these conditions.
It is common for motorcycle engines to produce a lot of heat during regular rides, long distances, or under performance conditions. A high temperature is likely to increase the rate of oxidation and deposit formation.
A high-temperature detergency additive prevents deposits from forming on critical engine components, helping control deposits and keep engines clean.
Many road bikes share an oil system with the engine, clutch, and transmission. These pose special formulation problems. A wet-clutch-compatible oil additive should offer the right friction properties to ensure smooth clutch operation and help avoid clutch slippage.
High loads and mechanical stress are encountered in gear systems during operation. Hard lubricant protection is needed to minimize wear on transmission components. An effective anti-wear lubricant additive can protect gears and engine components in heavy-duty motorcycle engines.
Temperature changes, short trips, and longer running cycles can contribute to sludge formation and contamination. Low-temperature dispersant technology helps maintain contaminant suspension, aiding cleaner oil flow during engine start-up. The oxidation-resistant engine oil package also helps to keep lubricant stable at high temperatures.

CHEMPOL 66025 is a high-grade motorcycle oil additive developed by Chempol for manufacturers of 4-stroke motorcycle oils. The CHEMPOL 66025 API SL Engine Oil Additive Package is intended for use by the formulator to attain balanced performance in applications that require:
The additive package is suitable for manufacturers developing motorcycle lubricants across various market segments, including premium motorcycle oils, private-label products, and export-oriented lubricant brands.
Additionally, CHEMPOL 66025 is suitable for formulations in other early API categories, such as API SJ engine oil formulations, API SG motorcycle lubricant additive packages, and API SF engine oil additive applications.
Chempol collaborates closely with lubricant blenders and technical teams to gain insight into formulation objectives and offer appropriate additive solutions to meet them.

As lubricant performance depends on engine cleanliness, it becomes crucial. CHEMPOL 66025 is a detergency additive for high-temperature applications that helps control deposits under severe operating conditions.
This facilitates cleaner engine areas and helps manufacturers develop reliable four-stroke motorcycle lubricants for demanding applications.
There may be sludge and contamination issues during short cycles and cold starts. The use of CHEMPOL 66025 enhances low-temperature dispersant technology. This will help keep lubricant systems clean and ensure consistent oil performance across various operating conditions.
Motorcycle engines and transmissions experience tremendous amounts of mechanical strain. The anti-wear lubricant additive technology in CHEMPOL 66025 provides lubrication to critical engine and gearbox parts. It is suitable for applications that demand good engine and motorcycle transmission lubricating properties.
Oxidation may reduce the lubricant’s effectiveness by forming deposits and altering the oil’s properties. CHEMPOL 66025 is designed for use in an oxidation-resistant engine oil package for extended service and high-temperature applications that promote oil oxidation.
In wet clutch systems, you need to get the right amount of friction. If there is excessive friction reduction, clutch slippage can occur, and if there is insufficient friction, smooth clutch engagement can be adversely affected. CHEMPOL 66025 supports JASO MA and JASO MA2 lubricant additive package applications by helping manufacturers formulate oils suitable for wet clutch motorcycles.
To achieve success, the motorcycle lubricant should protect the three interconnected systems:
CHEMPOL 66025 provides balanced additive chemistry designed to support all three lubrication requirements.
