Engine oil MANNOL Diesel TDI 5W-30 7909, synthetic motor oil, 10 L

MANNOL Diesel TDI 5W-30 7909 is a synthetic 10 L engine oil developed for modern diesel TDI passenger-car engines. The 5W-30 viscosity class ensures reliable cold-start behavior and consistent film strength at operating temperatures, while the formulation is intended to protect moving parts, reduce wear and help maintain fuel efficiency during everyday and long-distance driving.

Advantages

The synthetic base and additive package provide stable viscosity across a wide temperature range, good shear stability and effective protection against friction and wear. The oil supports engine cleanliness by helping to suspend contaminants and prevent deposits, and it is designed to contribute to smoother engine operation and extended component life under typical driving conditions.

Suitable for

• Passenger cars equipped with diesel TDI engines
• Everyday urban driving and commuting
• Long-distance and highway driving
• Cold climates where low-temperature start performance is required

When it may not be suitable

This oil is formulated specifically for diesel TDI engines and may not meet the requirements of petrol engines, heavy-duty diesel applications, or older engines that call for classic mineral oils or different viscosity grades. Always check the vehicle manufacturer’s engine oil specifications before use.

Key specifications

• Viscosity grade: 5W-30
• Type: fully synthetic motor oil
• Volume: 10 liters
• Designed for diesel TDI passenger-car engines
• Cold-start performance and stable lubrication at operating temperatures

How to use

Use this oil as part of regular engine maintenance following the vehicle manufacturer’s recommended oil change intervals and procedures. Warm the engine to operating temperature where applicable, drain the old oil and replace the oil filter before adding the new oil. Pour the specified quantity into the engine oil fill, check the level with the dipstick or electronic indicator, and run the engine briefly to circulate oil. Recheck the level and top up if necessary.

What to consider before purchase

• Confirm compatibility with the vehicle manufacturer’s oil specifications and recommended viscosity
• Ensure 10 L volume suits your service interval or multiple-top-up needs
• Verify intended use for diesel TDI passenger-car engines rather than petrol or heavy-duty diesel applications

Usage recommendations

For reliable performance, change the oil and oil filter at intervals recommended by your vehicle maker, monitor oil level regularly, and use the full 5W-30 grade specified for your diesel TDI engine to maintain protection and fuel economy.
