Oil Changes & Fluid Checks

Your engine still relies on clean oil. Honda typically recommends synthetic or a synthetic blend for their engines, and the Civic Hybrid is no exception.

Engine Oil: Follow Honda’s maintenance minder system or change every 5,000-7,500 miles using the specified oil weight (often 0W-20). Use a quality oil filter like a PurolatorONE or Mobil 1.
Transmission Fluid: The CVT transmission requires specific Honda HCF-2 fluid. Do NOT use standard automatic transmission fluid. A drain and fill is recommended every 30,000 miles or as per your owner’s manual. This is a critical step for CVT longevity.
Coolant: The engine and hybrid system have separate cooling circuits. Check both coolant reservoirs regularly. Use Honda Type 2 coolant, which is a long-life coolant.
Brake Fluid: Over time, brake fluid absorbs moisture, reducing its effectiveness. Flush and replace it every 2-3 years. A simple brake fluid tester can tell you its condition.

Tire Care & Rotation

Tires impact fuel economy and safety significantly. Proper tire care is non-negotiable.

Pressure: Check tire pressure weekly, especially before long trips. The correct pressure is listed on a sticker inside your driver’s side door jamb. Proper inflation is crucial for hybrid efficiency.
Rotation: Rotate your tires every 5,000-7,500 miles to ensure even wear. This extends tire life and maintains handling characteristics.
Alignment: Get an alignment check annually or if you notice uneven tire wear or steering pull.

Brake System Maintenance

Hybrids use regenerative braking, which means the conventional brakes aren’t used as much. While this saves wear, it can lead to other issues.

Inspection: Inspect brake pads and rotors at every oil change. Look for uneven wear, rust on the rotors, or sticking calipers.
Caliper Slides: Due to less frequent use, brake caliper slides can seize. Lubricate them annually with high-temperature synthetic grease to ensure smooth operation and even pad wear.

Hybrid Battery Health & Monitoring

The IMA battery is the heart of your hybrid system. Keeping it healthy is paramount.

Warning Lights: Pay immediate attention to any “Check Hybrid System” or IMA warning lights. These often indicate battery degradation or issues.
Driving Habits: Avoid aggressive acceleration and braking. Smooth driving helps prolong battery life.
Storage: If storing your hybrid for an extended period, ensure the 12V battery is charged, and ideally, start the car periodically to allow the IMA system to cycle.
