Common Engines Megane:
1.4L (E7J, K7J), 1.6L (K7M), 1.8L (F3P, F4P), 2.0L (F3R, F4R) Petrol; 1.9L (F8Q, F9Q) Diesel.
Common Engines Scenic:
1.4L (K7J), 1.6L (K7M, K4M), 2.0L (F4R) Petrol; 1.9L (F8Q, F9Q) Diesel.
Horsepower Range:
Approximately 75 HP (1.4L Diesel) to 140 HP (2.0L Petrol, depending on variant).
Torque Range:
Varies significantly by engine, e.g., around 115 Nm for 1.4L Petrol to 185 Nm for 2.0L Petrol.
Fuel Injection Type:
Multi-Point Fuel Injection (MPI) for most petrol engines, Direct Injection (DI) on some later variants or specific engines. Diesel engines use indirect injection or common rail (later models).
Oil Change Interval:
Typically 10,000 - 15,000 km or 12 months, whichever comes first, depending on engine and oil type (check manual for specific recommendations).
Timing Belt Replacement:
For petrol engines with timing belts (e.g., F3P, F4P, F4R), replacement is typically recommended every 60,000 - 120,000 km or 5-6 years, depending on engine type and driving conditions.
Engine Oil Specification:
API SJ/SL, ACEA A2/A3/B2/B3/B4. Viscosity grades commonly 5W-40, 10W-40, 10W-50. Refer to manual for precise grade based on engine and climate.
Coolant Specification:
Ethylene glycol-based coolant, typically green or blue. Renault Type D or similar is recommended. Capacity varies, around 5-7 liters.
Brake Fluid Specification:
DOT 3 or DOT 4 brake fluid. Typically replaced every 2-3 years.
Transmission Fluid Manual:
GL-4 rated manual transmission fluid, viscosity 75W-80 or 75W-90. Capacity around 2-2.5 liters.
Transmission Fluid Automatic:
Renaultmatic DPO/AL4 fluid or equivalent (Dexron III/Mercon on older specs). Capacity around 6 liters for a full flush.
