Castrol EDGE Professional LongLife III 5W-30 - Full Synthetic Engine Oil

Purpose and Specifications

Castrol EDGE Professional LongLife III 5W-30 is a full synthetic engine oil designed for modern gasoline and diesel engines that demand maximum performance under high pressure. This oil is formulated with Fluid TITANIUM technology, which strengthens under pressure to prevent metal-to-metal contact and reduce friction across all driving speeds.

Key Technical Specifications:

• Viscosity Grade: 5W-30 (flows easily at -30°C cold starts, maintains protection at 100°C operating temperature)
• Density: 0.851 g/ml at 15°C
• Kinematic Viscosity at 100°C: 11.6-12.0 mm²/s
• Performance Standard: ACEA C3 certified
• OEM Approvals: VW 504 00/507 00, Porsche C30 specifications
• Micro-filtered for superior cleanliness and verified using Castrol's Optical Particle Measurement System
• CO2 Neutral certified to highest global standards

This oil is engineered for vehicles with variable long drain intervals, meaning it maintains protection for extended periods between oil changes as recommended by your vehicle manufacturer.

When to Use / Replace?

Suitable For: Volkswagen Group vehicles (VW, Audi, Skoda, Seat) and Porsche models requiring VW 504 00/507 00 or Porsche C30 specification oils. Also suitable for any gasoline or diesel engine where ACEA C3 5W-30 is recommended in the owner's manual.

Replacement Interval: Follow your vehicle manufacturer's recommended service schedule, typically 15,000-20,000 km or 12 months for modern engines with long-life oil technology. Always check your owner's manual for exact intervals.

Operating Temperature Range: Provides protection from -30°C to +100°C, making it suitable for year-round driving in most climates.

Shelf Life: Store in a cool, dry place. Unopened containers maintain quality for several years when stored properly.

Frequently Asked Questions

Q: Can I use this oil in my non-VW vehicle?
A: Yes, if your vehicle manufacturer recommends an ACEA C3 5W-30 lubricant. Always verify the specification in your owner's manual before use. This oil is not suitable for engines requiring thicker oils (like 10W-40) or low-SAPS formulations for older vehicles.

Q: What does the 5W-30 rating mean?
A: The 5W indicates the oil flows easily at cold temperatures (5W = flows at -30°C), while 30 means it maintains proper thickness at normal engine operating temperature (100°C). This makes it ideal for both winter starts and summer protection.

Q: How does Fluid TITANIUM technology work?
A: The oil's molecular structure adapts under engine pressure, becoming stronger when pressure increases. This reduces friction, prevents metal-to-metal contact, and helps your engine maintain performance even during demanding driving conditions like acceleration or towing.
