Routine Fluid Checks and Changes

Fluids are the lifeblood of your car. Neglecting them can lead to costly repairs.

Engine Oil:
- Check: At least once a month. Park on a level surface, ensure the engine is warm but off for a few minutes. Pull the dipstick, wipe clean, reinsert fully, then pull again to read the level.
- Change: Consult your owner’s manual or follow the Maintenance Minder system. Typically every 5,000-7,500 miles using synthetic blend or full synthetic oil (e.g., 0W-20, as recommended). Always use a quality oil filter (like a PurolatorONE or Fram Ultra Synthetic).
CVT Fluid:
- Check: This is crucial for your 2015 Honda Civic EX Coupe CVT. Check according to your owner’s manual. Many Hondas use a special dipstick or inspection bolt.
- Change: Honda recommends specific intervals, often around 30,000-60,000 miles for severe driving conditions or as indicated by the Maintenance Minder. ONLY use Honda HCF-2 CVT fluid. Using incorrect fluid can severely damage the transmission. This is not a task to skimp on or use generic fluid.
Coolant:
- Check: Inspect the coolant level in the reservoir when the engine is cold. It should be between the MIN and MAX marks.
- Change: Typically every 5 years or 60,000 miles, then every 3 years or 30,000 miles. Use Honda’s long-life coolant (Type 2). Never mix different types of coolant.
Brake Fluid:
- Check: Ensure the level is between MIN and MAX in the reservoir.
- Change: Many experts recommend flushing brake fluid every 2-3 years, as it absorbs moisture over time, reducing braking performance and potentially damaging components.
Power Steering Fluid:
- Your 2015 Civic EX Coupe likely has electric power steering, so there’s no hydraulic fluid to check or change. One less thing to worry about!

Tire Care and Maintenance

Your tires are your only contact with the road, making their condition paramount for safety and efficiency.

Tire Pressure: Check monthly with a reliable gauge. Maintain the pressure recommended on the sticker inside your driver’s side door jamb, not the maximum pressure listed on the tire itself. Proper inflation improves fuel economy and tire life.
Rotation: Rotate your tires every 5,000-7,500 miles to ensure even wear. This extends tire life and maintains balanced handling.
Alignment: Get an alignment check annually or if you notice uneven tire wear or the car pulling to one side.
Tread Depth: Use a tread depth gauge or the “penny test.” If Lincoln’s head is fully visible, it’s time for new tires.

Brake System Inspection

Your brakes are critical for safety. Don’t wait until you hear grinding noises.

Pad Wear: Inspect brake pads visually at every oil change. Look for wear indicators or measure pad thickness. If they’re getting thin (typically below 3mm), it’s time for replacement.
Rotor Condition: Check for deep grooves, cracks, or excessive rust. Rotors can often be resurfaced if wear is minimal, but replacement is necessary for significant damage.
Brake Lines and Calipers: Look for leaks, cracks, or corrosion. Ensure calipers move freely.

Pro Tip: When replacing brake components, consider upgrading to ceramic pads for less dust and longer life, or slotted rotors for improved heat dissipation, especially if you drive aggressively or live in a hilly area. Always ensure components are compatible with your 2015 Honda Civic EX Coupe CVT.
