❓ FREQUENTLY ASKED QUESTIONS ABOUT OILS AND FLUIDS FOR CAPTUR HYBRID
Can I use an engine oil other than 5W-30?
Generally, no. Renault specifies 5W-30 with the C2/C3 standard to ensure engine protection, emissions compliance, and proper hybrid system operation. Using different viscosities or specifications can reduce engine life and cause problems with aftertreatment systems.
How often should I change my transmission oil?
While many hybrid transmissions are labeled "lubricated for life," experience suggests it's prudent to change the oil every 120,000 km or 36 months . Old oil loses its lubricating ability and can increase wear and noise.
Can the coolant be topped up with water?
Best avoided. It's recommended to use only a specific ready-made fluid (RTU) or the correct mixture of concentrate and demineralized water. Adding tap water reduces antifreeze and corrosion protection, increasing the risk of damage to the water pump, radiator, and internal components.
Can I mix liquids from different brands?
It's not recommended. If you need to top up and don't know the type of fluid, it's best to first thoroughly flush the system and switch to a single, certified product, rather than mixing different products with incompatible additives.
📌 LUBRICANT SUMMARY AND FINAL TIPS
To keep your Renault Captur 1.6 E-Tech Hybrid 145 HP efficient and safe, here is a summary of the recommended lubricants:
- Engine oil: 5W-30 (e.g. Valvoline SynPower RNO C3 or SynPower ENV C2/C3 range, according to Renault specifications).
