Castrol EDGE Turbo Diesel 5W-40 - Premium Engine Oil for Modern Diesel Engines

Purpose and Specifications

Castrol EDGE Turbo Diesel 5W-40 is a full synthetic engine oil engineered for modern diesel and gasoline engines that demand maximum performance and protection. This 4-liter container provides professional-grade lubrication with advanced deposit control technology.

What makes it work: The oil uses Fluid TITANIUM technology that strengthens the protective film between engine metal parts. This means less friction, better power delivery, and improved fuel efficiency—you get more horsepower from the same amount of fuel.

• Reduces engine deposits that build up in turbo diesel engines, keeping your engine cleaner and more responsive
• Lowers friction across all engine speeds, which improves acceleration and fuel economy
• Maintains viscosity from cold winter starts (5W rating) through high-temperature highway driving (40 rating)
• Protects against wear even under extreme pressure and temperature conditions
• Reduces emissions and helps extend the life of exhaust systems including diesel particulate filters (DPF)

Approved for: Volkswagen PD engines (VW 505.01 specification), Mercedes-Benz, Renault, Fiat, Ford, and other leading manufacturers requiring ACEA C3 or API SN/CF specifications.

When to Use and Replace

Suitable for: Modern turbo diesel engines and gasoline engines operating under high pressure and temperature. Ideal for vehicles with fixed service intervals and those equipped with diesel particulate filters.

Replacement intervals: Follow your vehicle manufacturer's recommended service schedule, typically every 10,000-15,000 km or annually, whichever comes first. Check your owner's handbook for exact intervals.

Operating temperature range: Performs reliably from -30°C (cold start protection) to over 100°C (high-temperature stability).

Storage: Store in a cool, dry place. Typical shelf life is 3-5 years when properly sealed and stored.

Frequently Asked Questions

Q: Can I use this oil in gasoline engines?
A: Yes. While formulated for diesel engines, Castrol EDGE Turbo Diesel 5W-40 is approved for both diesel and gasoline engines where the manufacturer recommends ACEA C3 or API SN/CF specifications. Always verify your vehicle's owner's handbook.

Q: What does the 5W-40 rating mean?
A: The 5W indicates cold-start performance—it flows easily at -30°C for reliable winter starting. The 40 rating means it maintains proper thickness at 100°C engine operating temperature, protecting your engine under load.

Q: Will this oil improve my fuel economy?
A: Yes. The reduced friction from Fluid TITANIUM technology helps engines run more efficiently. Testing shows improved fuel economy compared to standard 5W-40 oils, delivering more power from the same amount of fuel.
