2015 Honda CR-V Fluid Type Specs

The fourth-generation Honda CR-V, particularly the refreshed 2015 model, is known for its reliability and efficiency. This is due in large part to its "Earth Dreams" K24W9 engine and its Continuously Variable Transmission (CVT). To maintain that legendary Honda dependability, using the correct fluids is not just recommended—it's critical. Using a "universal" fluid or the wrong specification can lead to accelerated wear, poor performance, and even catastrophic failure of major components.

As an ASE-certified master technician, I’ve seen firsthand how a simple mistake like using the wrong transmission fluid can result in thousands of dollars in repairs. This guide will provide a comprehensive, factory-spec reference for every fluid your 2015 Honda CR-V requires. Always cross-reference with your owner's manual, but this sheet will serve as a detailed guide for you or your trusted mechanic.

Quick Reference

Fluid	Type/Spec	Capacity
Engine Oil	API Certified 0W-20	~4.6 qt (4.4 L) w/ filter
Engine Coolant	Honda Long Life Type 2 (Blue)	~6.5 qt (6.2 L)
Transmission Fluid	Honda HCF-2	~4.0 qt (3.8 L)
Transfer Case (AWD)	Honda HGO-1 (SAE 75W-85)	~0.5 qt (0.45 L)
Rear Differential (AWD)	Honda Dual Pump Fluid II	~1.5 qt (1.4 L)
Brake Fluid	Honda Heavy Duty DOT 3	~1.0 qt for flush
Power Steering	None (Electric Power Steering)	N/A
Washer Fluid	Commercial Solvent	~2.5 qt (2.4 L)

Engine Oil

The 2015 CR-V's 2.4L Earth Dreams engine is designed with tight tolerances to maximize efficiency. Because of this, it exclusively requires a low-viscosity oil.

• Specification: SAE 0W-20 that is API Certified.
• Capacity: Approximately 4.6 quarts (4.4 liters) with a filter change.

Notes: Using a heavier weight oil like 5W-20, 5W-30, or 10W-30 can impede oil flow on startup and interfere with the proper function of the VVT (Variable Valve Timing) system, potentially leading to performance issues and engine damage over time. Always look for the API "starburst" seal on the bottle. Honda does not have its own proprietary oil specification number like GM or Ford; adherence to the API certification and 0W-20 viscosity is key. Follow the vehicle's Maintenance Minder system for oil change intervals.

Engine Coolant

Honda's cooling systems are sensitive, and using the right coolant is essential to prevent corrosion and ensure proper heat transfer.

• Specification: Honda Long Life Antifreeze/Coolant Type 2.
• Capacity: The total system capacity is approximately 6.5 quarts (6.2 liters).

Notes: This is a blue, pre-diluted 50/50 coolant. It is a non-silicate, non-borate formula specifically designed for Honda’s aluminum engines and cooling system components. This is a P-HOAT (Phosphated Hybrid Organic Acid Technology) coolant. Never mix it with other colors or types of coolant (green, orange, yellow). Doing so can cause the coolant to gel, clogging the radiator and heater core and leading to overheating. If you cannot find the OEM Honda fluid, use a quality aftermarket Asian vehicle blue coolant that explicitly states it is a phosphate-based, silicate-free replacement for Honda Type 2.

Transmission Fluid (CVT)

This is the single most critical fluid for the 2015 CR-V. All 2015 models are equipped with a CVT, not a traditional multi-gear automatic.

• Specification: Honda HCF-2 Transmission Fluid.
• Capacity: A standard drain and fill requires approximately 4.0 quarts (3.8 liters).

Notes: Under no circumstances should any other fluid be used. Do not use universal CVT fluid, multi-vehicle ATF, or even other Honda transmission fluids like ATF-Z1 or ATF-DW1. Using the incorrect fluid will quickly destroy the steel belt and pulley system of the CVT, leading to a complete transmission failure. A drain and fill only replaces about half the fluid in the transmission, so sticking to a regular 30,000-mile service interval is crucial for longevity.

AWD System Fluids (If Equipped)

If your CR-V is an All-Wheel Drive model, it has two separate driveline components that require their own specific fluids.

• Transfer Case Specification: Honda HGO-1 Hypoid Gear Oil (SAE 75W-85). Capacity: ~0.5 quarts (0.45 liters).
• Rear Differential Specification: Honda Dual Pump Fluid II. Capacity: ~1.5 quarts (1.4 liters).

Notes: These two units are not connected and cannot share fluid. The transfer case, located at the front of the driveshaft, requires a specific hypoid gear oil. The rear differential contains a multi-plate clutch system that engages the rear wheels, and it requires the proprietary Dual Pump II fluid. Using standard gear oil in the rear differential will ruin the clutch packs and disable the AWD system. These are often overlooked services but are vital for the proper function of the AWD system.

Brake Fluid

Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This moisture lowers the boiling point of the fluid and can corrode internal brake components.

• Specification: Honda Heavy Duty Brake Fluid DOT 3.
• Capacity: A full system flush and bleed will require approximately 1 quart.

Notes: While DOT 4 fluid has a higher boiling point and is technically compatible, it is not necessary for a stock vehicle and is typically more expensive. The most important factor is not the number (3 vs 4) but the freshness of the fluid. Always use fluid from a new, sealed container. Plan on flushing the brake fluid every 2-3 years, regardless of mileage, to maintain peak braking performance and safety.

Power Steering Fluid

The 2015 Honda CR-V uses an Electric Power Steering (EPS) system. There is no hydraulic pump, no hoses, and no fluid to check or change. This is a maintenance-free system.

Windshield Washer Fluid

• Specification: Any good quality commercial windshield washer solvent.
• Capacity: Approximately 2.5 quarts (2.4 liters).

Notes: For regions with freezing winter temperatures, be sure to use a fluid with a de-icing agent and a low freezing point to prevent the reservoir and lines from cracking.

Adhering to these factory fluid specifications is the most effective way to ensure your 2015 CR-V runs smoothly and reliably for many years to come. When in doubt, defer to the OEM-branded fluid.
