The 2021 Honda CR-V requires 0W-20 full-synthetic engine oil and about 3.7 quarts with a filter for an oil change.
For the 2021 CR-V, which uses the 1.5-liter turbocharged engine in most trims, this guide explains the oil type, capacity, and maintenance intervals, plus tips for buying and changing oil. Always verify the exact specification in your owner’s manual or on the under-hood oil-fill cap.
Oil specifications
Viscosity, standards and capacity
The CR-V’s 1.5L turbo engine requires a light, fully synthetic oil to optimize fuel economy and emissions. The recommended viscosity is 0W-20, and the oil should meet ILSAC GF-6 (or newer) standards.
- Viscosity: 0W-20
- Formulation: Full synthetic (Honda-recommended; compatible with other synthetic 0W-20 oils)
- Standards: Meets ILSAC GF-6 (or newer) specifications and API SN/SN+ compatibility
- Capacity (with filter): approximately 3.7 quarts
Using a 0W-20 full-synthetic oil that meets GF-6 or newer ensures proper lubrication and performance for the turbocharged engine.
Capacity and service intervals
Oil capacity and maintenance intervals depend on driving conditions; for the 2021 CR-V with the 1.5L engine, plan for roughly 3.7 quarts with a new filter. Normal service intervals are designed around typical driving patterns.
- Capacity: ~3.7 quarts with filter (may vary slightly by engine variant)
- Normal-change interval: about 7,500 miles or 12 months, whichever comes first
- Severe conditions: shorten the interval to roughly 3,750–5,000 miles or 6 months
Always check the owner’s manual and the vehicle’s oil-change label for the exact numbers based on your trim and region.
Practical guidance for oil shopping and changes
When shopping, select a 0W-20 full-synthetic oil that carries a reputable brand and meets GF-6 or newer standards. Honda Genuine Oil is the default, but many top brands offer compatible products. Replace the oil filter at every change, and ensure the new oil is added until the dipstick shows the correct level. If you’re unsure, a quick visit to a Honda-certified shop can ensure the correct specification and drain quantity.
Summary
For a 2021 Honda CR-V, use 0W-20 full-synthetic oil, about 3.7 quarts with a new filter. Follow normal service intervals (roughly every 7,500 miles / 12 months) unless you drive under severe conditions, in which case change more frequently. Always verify with the owner’s manual or oil cap, and consider your climate and driving habits when deciding on service frequency. Regular oil changes protect engine longevity and performance.
