Purpose and Specifications

Shell Helix Ultra Professional AR-L 5W-30 RN17 is a fully synthetic premium engine oil engineered for high-performance Renault diesel and petrol engines. This oil meets the demanding Renault RN17 specification and ACEA C3 standard, making it ideal for modern vehicles with advanced emission control systems.

Key Technical Benefits:

• Low-SAPS formulation protects diesel particulate filters (DPF) from clogging, extending filter life and reducing maintenance costs
• Works in extreme temperatures: flows smoothly in cold starts and maintains protection at high engine temperatures
• Reduces engine sludge and varnish buildup, keeping pistons and valves clean
• Compatible with turbocharged and supercharged engines
• Supports fuel efficiency and lower oil consumption between top-ups

When to Use and Replace?

Use this oil in Renault vehicles (and compatible high-performance engines) that specifically require RN17 approval. Check your owner's manual to confirm compatibility before use.

Replacement Schedule: Follow your vehicle manufacturer's recommended service intervals, typically every 10,000–15,000 km or annually, whichever comes first. The 5-liter bottle covers most standard oil changes with room for top-ups.

Storage: Keep unopened bottles in a cool, dry place. Shelf life is typically 3–5 years when stored properly.

Frequently Asked Questions

Q: Can I use this oil in petrol engines?
A: Yes. Shell Helix Ultra Professional AR-L 5W-30 RN17 is approved for both diesel and petrol Renault engines meeting RN17 specifications.

Q: Why is low-SAPS important?
A: Low-SAPS (low ash, phosphorus, and sulphur) protects your DPF system from blockages. A clogged DPF is expensive to replace, so this formulation saves you money on repairs.

Q: Is this oil suitable for older Renault models?
A: No. Always check your vehicle's manual first. This oil is designed for modern Renault engines requiring RN17 approval. Using the wrong specification can damage your engine.
