What fluids need to be changed in a Honda CR-V?
The fluids you typically need to change in a Honda CR-V include engine oil and its filter, transmission fluid (CVT or automatic, depending on the model), engine coolant, and brake fluid. If you drive an all‑wheel‑drive (AWD) CR‑V, you may also service the rear differential fluid and, in some variants, the transfer case fluid. Many newer CR‑Vs use electric power steering, so there is no hydraulic power steering fluid to replace.
Core fluids you should change on most CR‑Vs
These items form the baseline of routine maintenance and are commonly listed in Honda’s maintenance schedules. The exact intervals and fluid types depend on the model year, engine, and driving conditions, so always verify with your owner's manual.
- Engine oil and oil filter
- Transmission fluid (CVT fluid for CVT-equipped models; conventional ATF for non-CVT automatics)
- Engine coolant (antifreeze)
- Brake fluid
These are the core fluids that most CR‑V owners will replace during routine service. Using the prescribed fluids and following the recommended change intervals helps protect the engine, transmission, cooling system, and braking performance across the life of the vehicle.
Drivetrain-specific fluids for AWD and other configurations
AWD CR‑Vs may have additional fluids that require periodic changes. The rear differential holds gear oil, and some models with AWD may also have a transfer case that requires its own fluid. Availability and intervals can vary by year and drivetrain configuration, so consult the manual for your exact version.
- Rear differential gear oil (for AWD models)
- Transfer case fluid (if applicable to your model)
For front‑wheel‑drive (FWD) CR‑Vs, the second list items may not apply. Always confirm which components your particular vehicle has and follow Honda’s guidance or your dealer’s service recommendations.
Power steering and other fluid considerations
Most modern CR‑Vs use electric power steering, which means there is no hydraulic power steering fluid to replace. If you own an older CR‑V or a specific trim with hydraulic power steering, check the owner’s manual to confirm whether a power steering fluid is required and what type to use.
Fluid specifications and typical service intervals
Intervals can vary by year, engine, and driving conditions. The following are general guidelines you may see in service schedules, but always rely on the exact specifications in your owner’s manual.
- Engine oil: roughly every 5,000–7,500 miles for conventional oil; 7,500–10,000 miles or more for full synthetic oil, depending on driving conditions
- CVT/ATF: commonly around 60,000 miles under normal conditions; more frequent changes under severe driving
- Engine coolant: typically every 10 years or about 120,000 miles for Honda long-life coolant; older schedules may differ by model
- Brake fluid: generally every 2–3 years (regardless of mileage) to prevent moisture buildup
- Rear differential fluid: often in the 60,000–100,000 mile range for AWD models; consult the manual for your exact interval
- Transfer case fluid: commonly 60,000–100,000 miles if the model has a transfer case; some CR‑Vs do not have a serviceable transfer case
Because CR‑V generations differ in their drivetrain and fluid specifications, always refer to the exact maintenance schedule for your model year and drivetrain. A dealer or qualified technician can verify the correct fluid type (for example, Honda DW‑1 CVT fluid) and the precise change intervals.
Summary
To keep a Honda CR‑V running reliably, prioritize engine oil and filter changes, regular CVT or ATF service, coolant renewal, and brake fluid maintenance. If the vehicle is AWD, plan for rear differential fluid changes and, where applicable, transfer case fluid. Electric power steering on modern CR‑Vs means no power steering fluid in most cases. Always follow the specifics in your owner’s manual or consult your dealer for the exact fluid types and service intervals for your year and drivetrain.
How often should I change the differential fluid on my Honda CRV?
You should change the differential fluid on an AWD Honda CR-V approximately every 30,000 to 60,000 miles. The first change is often around 15,000 miles, as recommended by the maintenance minder, and then every 30,000 miles thereafter. For FWD models, the differential fluid is typically changed with the transmission fluid because they are a single unit.

Factors that influence the interval
- Maintenance Minder: Your car's maintenance minder will alert you when a change is needed, often at an earlier mileage for the first service (around 15,000 miles) to account for break-in material.
- Driving conditions: If you frequently tow or drive in severe conditions, you may need to change the fluid more often.
- Owner's Manual: Always consult your owner's manual for the most accurate recommendations for your specific model year.
- Friction: The fluid is subject to friction and heat from the metal-on-metal contact in the gears, which can cause wear over time. Changing it helps prevent costly damage to the differential.
What fluids need to be changed in a Honda CRV?
WHAT COUNTS AS SEVERE & WHAT CHANGES
| AREA | NORMAL | SEVERE ADJUSTMENT |
|---|---|---|
| Engine air & cabin filters | 15,000–30,000 miles | 10,000–20,000 miles |
| Transmission / e‑CVT fluid | As Minder indicates | Sooner under heat/grades |
| Rear differential fluid (AWD) | As Minder indicates | Sooner with mountain driving/towing |
| Brake fluid | ~3 years | ~3 years (time‑based) |
What is included in a Honda CR-V tune up?
Engine vacuum test to detect air leaks and broken seals. Exhaust emissions check to find issues that were not uncovered in baseline assessments. Inspection/replacement of spark plugs, caps, filters, and other components as needed. Inspection/replacement of belts, hoses, fluids, and connections.
How often should Honda CR-V transmission fluid be changed?
The Honda CR-V transmission fluid change interval is typically every 30,000 miles for hard driving or 50,000 to 60,000 miles for normal driving conditions, but you should always consult your owner's manual for the most accurate recommendation for your specific model year and driving habits. Transmission filters may need to be replaced every other fluid change.

Factors affecting the interval
- Driving conditions: If you frequently tow, drive in mountainous areas, or experience severe conditions, change the fluid more often, around every 30,000 miles.
- Normal driving: For everyday driving, you can extend the interval to 50,000 to 60,000 miles.
- Filter replacement: Some sources recommend replacing the transmission filter roughly every second or third fluid change, as Honda sometimes considers the filter to be a "lifetime" component, though many mechanics advise against this.
How to check your transmission fluid
- Warm up the engine for 10-20 minutes.
- Check the fluid level and condition. The fluid should be reddish and not dark brown or black, which can indicate it's time for a change.
- Look for warning signs, such as a burning smell, difficulty shifting, or slipping gears, which may mean it's time to change the fluid sooner.
