PETRONAS Urania Prime Classic 20W-50
Premium Engine Oil for Older Generation Diesel Engines with StrongTech™ Technology
Product code: 88058M12EU | Packaging: 5 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.

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
