Purpose and Specifications

LIQUI MOLY TOP TEC 4400 5W30 5L is a premium synthetic technology engine oil designed for year-round protection in modern diesel and petrol engines, especially Renault models with diesel particulate filters (DPF). Its low-ash formula keeps DPFs clean and extends their life by minimizing ash buildup, while flowing easily at cold starts down to -30°C for instant lubrication and staying thick at high temps up to 150°C to protect turbos and engines during heavy loads.

This 5-liter can delivers outstanding wear protection, reduces fuel use by cutting friction, and prevents sludge for smoother running and longer engine life. Approved for MB 229.51, ACEA C4, MB 226.51, RENAULT RN0720, FIAT 9.55535-S4, it suits common-rail diesels, gas vehicles (CNG/LPG), and those with turbos or catalytic converters.

When to Use / Replace?

Use this oil in Renault diesels requiring RN0720 spec, Mercedes with DPF, Fiat, or any vehicle needing low-ash C4 protection for clean emissions and efficiency. Ideal for all-season driving, from city stop-go to highway cruising.

• Replace every 20,000-30,000 km or 12-24 months per manufacturer guidelines to maintain peak performance and DPF health.
• Shelf life: Up to 5 years unopened in cool, dry storage.
