Purpose and Specifications

Castrol GTX 5W30 RN17 1L is a premium fully synthetic engine oil designed for Renault vehicles requiring RN17 specification and ACEA C3 standards. Its 5W30 viscosity flows easily at cold starts down to -30°C for quick protection, while staying thick up to 150°C to shield your engine from heat damage during long drives or heavy loads.

The 3X-Clean formula fights sludge from short trips, heat, and dirt, keeping your engine 35% cleaner than industry standards for smoother performance and longer life. It provides superior anti-wear protection, resists breakdown, and works safely with diesel particulate filters and gasoline engines.

• Key Benefits: Cleans existing sludge, prevents new buildup, reduces wear, minimizes oil consumption
• Ideal for: Renault petrol/diesel engines (Euro 6d diesel from 2018+), everyday driving, frequent short trips
• Shelf Life: 5 years unopened when stored cool and dry

When to Use / Replace?

Use this oil in Renault models specifying RN17 5W30 for optimal protection. Replace every 10,000-15,000 km or 12 months under normal conditions; shorten to 7,500 km or 6 months for severe use like towing, city stop-go traffic, or extreme temperatures (-30°C to 40°C+).

Check oil level monthly; top up if low. Always follow your owner's manual for exact intervals to avoid engine damage.
