PETRONAS Urania Prime Classic 20W-50

Premium Engine Oil for Older Generation Diesel Engines with StrongTech™ Technology

Product Code: 88058251EU | Packaging: 200 Litres

Product Description

PETRONAS Urania Prime Classic 20W-50 is a top-tier engine oil for heavy-duty diesel engines, developed with advanced StrongTech™ technology. This proven formulation creates an exceptionally durable lubricating film that protects the engine, maintains its performance, and ensures your trucks stay on the road longer. The higher 20W-50 viscosity grade provides optimal lubrication for older engines with larger tolerances and for operation in warmer climatic conditions. The result is a lower total cost of ownership and maximum reliability for your fleet.

Who is it for?

This oil is an ideal choice for:

• Older generation heavy-duty diesel engines - where API CF-4 specification is required
• Engines with larger tolerances - worn or older designs requiring higher viscosity
• Turbocharged and naturally aspirated diesels - classic engine designs
• On-road and Off-road Use - trucks, construction and agricultural machinery
• Operation in warmer climatic conditions - higher viscosity ensures better lubrication at high temperatures
• Classic diesel applications - without modern emission systems

Product Replacement: PETRONAS Urania Prime Classic 20W-50 is the successor to the proven Urania 800 20W-50.

Technical specifications and approvals

Physical Properties

When to Choose 20W-50 Instead of 15W-40?

Choose 20W-50 if:

• ✅ You have an older engine with more wear
• ✅ The engine consumes more oil
• ✅ You operate the vehicle in a warmer climate
• ✅ The engine exhibits greater tolerances between components
• ✅ Manufacturer Recommends Higher Viscosity

Choose 15W-40 if:

• ⚪ You Operate the Vehicle in Colder Climates
• ⚪ The Engine is in Good Technical Condition
• ⚪ You Need Better Cold Start Performance

Recommendations for use

💡 TIP: For maximum vehicle performance, combine PETRONAS Urania with PETRONAS Tutela operational fluids.

⚠️ Important: Always consult your vehicle's manual to verify the recommended viscosity grade and specifications for your specific engine.

Safety and handling

• Avoid skin contact
• In case of contact, wash immediately with soap and water
• Do not discharge into drains, soil, or water
• For detailed information on storage and safe handling, consult the Safety Data Sheet (SDS)
