MERCEDES 229.51 5W30 is a fully synthetic engine oil engineered specifically for Mercedes-Benz high-performance engines. This oil meets the stringent MB-Approval 229.51 standard and is suitable for both diesel and gasoline engines that require this specification.

Key Performance Benefits:

• Reduces engine friction and wear, extending engine life
• Improves fuel economy and reduces CO2 emissions
• Keeps engine components clean and prevents harmful deposit buildup
• Maintains consistent performance in demanding driving conditions
• Compatible with modern emissions systems including diesel particulate filters (DPF) and catalytic converters

Operating Temperature Range: Performs reliably from -39°C (cold start) to 220°C (flash point), ensuring safe lubrication in both winter and high-temperature driving conditions.

When to Use / Replace?

Use this oil in any Mercedes-Benz engine requiring MB 229.51 specification. Follow your vehicle manufacturer's recommended oil change intervals, which typically range from 15,000 to 50,000 km or annually (whichever comes first), depending on your specific model and driving conditions. Extended oil change intervals up to 50,000 km are possible with this fully synthetic formulation when approved by your vehicle manufacturer.

Storage: Keep in a cool, dry, well-ventilated area away from direct sunlight. Shelf life is typically 3-5 years when stored properly.

Frequently Asked Questions

Q: Can I use this oil in both petrol and diesel Mercedes engines?
A: Yes. MERCEDES 229.51 5W30 is approved for both gasoline and diesel engines that require MB 229.51 specification. Always verify your vehicle's owner manual to confirm the correct specification.

Q: Is this oil suitable for vehicles with diesel particulate filters?
A: Yes. This is a Low SAPS (Sulphated Ash, Phosphorus, Sulfur) oil, making it fully compatible with modern emissions control systems including DPF and SCR technology.

Q: How does 5W30 viscosity work?
A: The '5W' means the oil flows easily at cold temperatures (winter starts), while '30' indicates it maintains proper thickness at normal engine operating temperatures. This balance ensures reliable protection year-round.
