2021 Honda Civic Maintenance Schedule
Here are the 2021 Honda Civic's service intervals, drawn from the manufacturer's published maintenance schedule — the key services, when each is due, and what each one does.

Service intervals
| Service | Every (km / mi) | Or every |
|---|---|---|
| Oil & Filter Change | 12,000 km / 7,500 miHonda's Maintenance Minder sets the interval from your driving — often ~12,000 km / 7,500 mi, but as little as 5,000–6,000 mi with cold-weather short trips. Replace at least once a year. | 12 months |
| Tire Rotation | 12,000 km / 7,500 miMaintenance Minder sub-code 1 — usually with each oil change. | — |
| Engine & Cabin Air Filters | 48,000 km / 30,000 miMaintenance Minder sub-code 2. Halve this in dusty conditions. | — |
| Transmission Fluid | —Maintenance Minder sub-code 3. Inspect only under normal use; under severe use plan on a change around 40,000 km / 25,000 mi. | — |
| Spark Plugs | 160,000 km / 100,000 mi | — |
| Engine Coolant | 160,000 km / 100,000 miMaintenance Minder sub-code 5. First change at ~160,000 km / 100,000 mi or 10 years; every ~96,000 km / 60,000 mi thereafter. | 120 months |
| Brake Fluid | —Maintenance Minder sub-code 7 — Honda specifies every 3 years regardless of mileage. | 36 months |
| Rear Differential Fluid (AWD) | 48,000 km / 30,000 miMaintenance Minder sub-code 6 — AWD models only. | — |

Rough estimates in CAD for scheduled-maintenance parts and fluids, based on typical prices — not live retailer quotes, and your costs will vary. Wear/replacement items (brakes, tires, battery) and diagnostics aren't included.
Fluids & capacities
Capacities are "with filter" and vary by engine — check your Honda Civic's engine option below.
| Engine oil | 0W-20 full synthetic — 4.4 qt (4.2 L) |
| Engine coolant | Honda Type 2 (blue) long-life coolant |
| Spark plugs | Iridium, ~100,000 mi service life (factory-set gap) |
| CVT fluid | Honda HCF-2 (CVT) |
| Brake fluid | DOT 3 |
| Engine oil | 0W-20 full synthetic — 3.7 qt (3.5 L) |
| Engine coolant | Honda Type 2 (blue) long-life coolant |
| Spark plugs | Iridium, ~100,000 mi service life (factory-set gap) |
| CVT fluid | Honda HCF-2 (CVT) |
| Brake fluid | DOT 3 |
Confirm the grade and capacity against your owner's manual before servicing — figures can differ by trim, drivetrain and market.
What each service does
Oil & Filter Change
Rather than a fixed mileage, Honda's onboard monitor measures engine conditions and tells you when oil life is low (main code A or B).
Tire Rotation
Rotating tires evens out tread wear. Honda pairs it with the oil-change service.
Engine & Cabin Air Filters
The engine air filter and dust/pollen (cabin) filter are serviced together under sub-code 2, roughly every 48,000 km / 30,000 mi.
Transmission Fluid
Clean CVT/automatic fluid keeps shifts smooth. Honda schedules it by the monitor's sub-code 3 rather than a fixed mileage.
Spark Plugs
Honda's direct-injection engines use long-life plugs rated for roughly 160,000 km / 100,000 mi (Maintenance Minder sub-code 4).
Engine Coolant
Honda Long Life Coolant is built for a long first interval, then more frequent changes to keep the cooling system protected.
Brake Fluid
Brake fluid absorbs moisture, lowering its boiling point. Honda replaces it on a 3-year clock, not by distance.
Rear Differential Fluid (AWD)
On all-wheel-drive Hondas, the rear differential fluid is serviced under sub-code 6 to protect the AWD system.
These intervals are drawn from the 2021 Honda Civic's manufacturer maintenance schedule for normal service. Your vehicle's owner's manual remains the final authority, especially for "severe service" conditions like towing, short trips or dusty roads. BoxKitz links you straight to the manufacturer's manual and live recall data once you add the vehicle.
