Purpose and Specifications

Castrol GTX 0W-20 RN17 FE 5L is a fully synthetic engine oil designed for specific Renault and Dacia petrol and diesel engines requiring RN17 FE approval. It delivers fast lubrication at cold starts down to -35°C and stays strong up to 150°C, keeping your engine protected in all weather.

This oil fights sludge three ways - against heat, dirt, and short trips - keeping engines up to 35% cleaner than standard. It boosts fuel economy, protects particulate filters (GPF and DPF), and extends engine life with premium anti-wear additives for smooth performance.

• Perfect for Renault Clio V, Captur II, Megane IV, Arkana, Kadjar, Dacia Sandero, Jogger, Duster II, and Nissan Qashqai 1.3 DIG-T MHEV
• ACEA C5 rated for low-viscosity modern engines
• 5L size for full oil changes

When to Use / Replace?

Use this oil in vehicles built since 2018 needing RN17 FE spec (not compatible with older Renault specs like RN0700). Ideal for city driving, short trips, or extreme temps where quick flow and cleanliness matter.

Replace every 15,000-30,000 km or 12 months, or sooner under heavy loads like towing or dusty roads. Shelf life is 5 years unopened in cool, dry storage.
