ARISO SAE 20W-50 API CF-4
Synthetic
Diesel Engine Oil

Synolex Diesel Engine Oils are available in multiple performance grades and formulations—mineral, synthetic, and full synthetic—to meet the demands of various engine types.

Formulated with high quality base oils and advanced additive technologies, these products are engineered for excellence, ensuring superior protection and consistent optimum performance across diverse driving conditions.

Synolex Ariso 20W-50 CF-4/CF is a synthetic diesel engine oil that not only ensures constant oil pressure, but also neutralizes negative effects of high sulfur content of diesel.

Synolex Ariso 20W-50 CF-4/CF has been designed for modern diesel engines when healthy engine performance under extremely high operating temperature and pressure is vital.

Product Information
Description

Key Features and Benefits:

  • Outstanding Engine Protection
  • Provides comprehensive protection against wear, deposits, oxidation, and corrosion. Advanced additives help maintain engine cleanliness, safeguard critical components, and ensure reliable performance under both normal and severe operating conditions.
  • Maintained Oil Pressure
  • Ensures that the lubricant consistently circulates throughout the engine, reaching all critical components such as bearings, pistons, and camshafts. By maintaining optimal oil pressure, the engine experiences reduced friction, improved wear protection, and stable performance under both low and high-temperature conditions. This also prevents damage caused by oil starvation, supports smooth operation, and extends the overall life of the engine.
  • High Detergency Level
  • Effectively cleans and prevents the buildup of carbon deposits, sludge, and other contaminants that can form in engines requiring API CF-4 specification. This helps maintain clean pistons, valves, and combustion chambers, ensures smooth and consistent engine operation, reduces knocking, and prolongs engine life.
  • Outstanding Wear Protection
  • Provides a strong and durable lubricating film that protects critical engine components such as pistons, camshafts, and bearings from metal-to-metal contact, even under high loads and severe operating conditions.
  • Low Evaporation
  • Formulated with high-quality base oils that exhibit low volatility, helping to minimize oil evaporation under high operating temperatures typical of diesel engines. This reduces oil consumption, maintains proper oil level for longer periods, and ensures consistent lubrication. As a result, engine components remain well protected, deposit formation is minimized, and overall engine efficiency and durability are enhanced.

Specification:

Recommended Applications:

Synolex Ariso CF-4 products are recommended for use in high speed four stroke-cycle diesel engines used on both heavy-duty on-highway (less than 0.05% wt. sulphur fuel) and off highway (less than 0.5% wt. sulphur fuel) applications.

Vehicle owners and operators should follow their vehicle manufacturer’s recommendations on engine oil viscosity and performance standard. Synolex  Ariso 20W-50 CF-4 can be used in applications calling for SAE 20W-50 and API CF-4.

Performance Benefits:

  • Helps Extend Engine Life
  • Formulated with high-quality base oils and advanced additive technology, the oil reduces friction, minimizes component wear, and prevents harmful deposits, thereby helping to extend overall engine life and maintain long-term reliability.
  • Reduces Maintenance Costs
  • By providing superior wear protection, controlling deposits and sludge, and maintaining engine cleanliness, this engine oil helps minimize breakdowns and extend service intervals. As a result, it lowers overall maintenance costs and reduces the need for frequent repairs.
  • Excellent Fuel Economy:
  • Optimized friction-reducing properties help improve engine efficiency, contributing to lower fuel consumption and reduced operating costs while maintaining strong engine performance.

Steps to Take When Converting from Other Oils:

If you decide to use Synolex Diesel Engine Oil in vehicles that previously used other lubricants, it is recommended follow the vehicle manufacturer’s recommendations on engine oil viscosity and performance level. Synolex Ariso 20W-50 CF-4 can be used in applications calling for SAE 20W-50 and API CF-4.

Handling and Storage:

Synolex Diesel Engine Oils should not be mixed with other similar lubricants. Prevent the entry of particles such as moisture and dust by closing the product container after each use. Store in a closed container away from heat, sparks, flames and oxidizing agents. Handle with caution and in accordance with authorized instructions.

Health and Safety:

Health and safety instructions are contained in the relevant Material Safety Data Sheet (SDS) which can be obtained from the head office.

Environmental Protection:

To prevent any harm to the environment and human health, it is necessary to dispose of used oil safely. Use a professional oil disposal service and never pour used oil into drains or onto the ground.

Packaging:

  • Plastic bucket- 20 Liter
  • Metal drum- 208 Liter
