Product detailed description

PETRONAS Urania Prime Classic 40

Monograde engine oil for older diesel engines and transmissions - higher viscosity

Product Code: 88061251EU | Packaging: 200 Liters

Product Description

PETRONAS Urania Prime Classic 40 is a high-quality SAE 40 monograde engine oil for heavy-duty diesel engines, specifically formulated for older commercial vehicles and high-speed turbocharged diesel engines. The higher SAE 40 viscosity grade provides optimal lubrication for older engines with larger tolerances and for operation in warmer climatic conditions. Thanks to its versatile usability, it is suitable not only for engines but also for transmissions, differentials, and final drives where API CF SAE 40 specification is required.

Who is it for?

This oil is an ideal choice for:

• Older Commercial Vehicles - where API CF specification is recommended
• High-Speed Turbocharged Diesels - classic designs
• Engines with larger tolerances - worn or older designs
• On-road and Off-road Use - trucks, construction and agricultural machinery
• Drivetrain Systems - transmissions, differentials, and final drives requiring API CF SAE 40
• Operation in warmer conditions - higher viscosity ensures better lubrication at high temperatures
• Universal Application - one oil for multiple uses

Product Replacement: PETRONAS Urania Prime Classic 40 is the successor to the proven Urania 500 SAE 40.

Key Benefits

🧼 Engine Cleanliness and Protection

• Maintains piston cleanliness
• Minimizes deposit formation
• Effective wear protection
• Higher viscosity for better protection of worn engines

🛡️ Soot and Viscosity Control

• Helps disperse soot
• Reduces soot-induced oil thickening
• Maintains stable viscosity during operation
• Resistance to fuel dilution

⚗️ Acid Neutralization

• Excellent TBN Retention (Total Base Number)
• Effectively neutralizes acidic combustion products
• Corrosion protection

🔧 Universal Application

• Suitable for engines and drivelines
• Meets API CF requirements for transmissions
• One oil for multiple applications = simplified storage
• Ideal for warmer climatic conditions

Technical specifications

Physical Properties

When to choose SAE 40 instead of SAE 30?

Choose SAE 40 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
• ✅ The manufacturer recommends a higher viscosity SAE 40
• ✅ You need a stronger lubricating film

Choose SAE 30 if:

• ⚪ You operate the vehicle in a milder climate
• ⚪ The engine is in better technical condition
• ⚪ The manufacturer recommends a lower viscosity

Areas of use

Engine applications:

• Older diesel truck engines with more wear
• High-Speed Turbocharged Diesels
• Construction and agricultural machinery in warm regions
• Stationary diesel units
• Engines with higher oil consumption

Transmission applications:

• Mechanical gearboxes requiring SAE 40
• Differentials
• Final drives
• Equipment with higher operating temperatures

What is a single-grade oil and when to use it?

Single-grade oil has a single viscosity grade (SAE 40) and is designed for:

• ✅ Older engines without modern emission systems
• ✅ Operation in warm climatic conditions
• ✅ Applications where the manufacturer recommends a single-grade oil
• ✅ Drivelines and differentials
• ✅ Stationary engines and generators

Benefits of higher SAE 40 viscosity:

• Stronger lubricating film at high temperatures
• Better protection for worn engines
• Lower oil consumption
• Higher oil pressure in the system

Recommendations for use

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

💡 TIP: Monograde SAE 40 oil is ideal for older equipment with greater wear and for operation in warmer climatic conditions.

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)
