The 2018 Honda CR-V typically requires 0W-20 synthetic engine oil. Use Honda Genuine 0W-20 or an equivalent that meets API SN or later and ILSAC GF-5/6 standards.
In practice, the exact specification is designed to optimize fuel economy and engine protection for the CR-V’s common 2018 configuration. Always verify the requirement in your owner's manual or on the under-hood label for your specific trim and market.
Oil type and specifications
Honda standardized on a 0W-20 viscosity for the 2018 CR-V in most regions to balance efficiency and protection. The engine in most US models is designed to run on 0W-20 synthetic oil, and the oil must meet certain industry standards to ensure proper performance and warranty coverage.
Viscosity and approvals
The recommended viscosity is 0W-20. Use an oil that meets API SN (or later) and ILSAC GF-5 (or later) specifications. Honda generally endorses full synthetic or synthetic-blend oils that meet these standards.
Where to find the exact requirement
Always check the owner's manual and the oil-fill cap or under-hood label for the precise grade and specification required for your vehicle’s engine and market. If you’re unsure, ask a Honda dealer or trusted mechanic to confirm before you buy oil.
Practical guidance for selecting oil
To keep your CR-V running as intended, choose a high-quality 0W-20 oil that is specifically labeled as meeting API SN or later and ILSAC GF-5/6. The following options are commonly compatible with the 2018 CR-V's specification.
Common oil options that meet the spec include the following. Choose a reputable brand and confirm the product label shows 0W-20 and API SN or later.
- Honda Genuine 0W-20 Engine Oil
- Mobil 1 0W-20 Advanced Full Synthetic
- Castrol EDGE 0W-20 Full Synthetic
- Valvoline Advanced Full Synthetic 0W-20
All of these oils are designed to meet the 0W-20 specification and API SN or later, and they are widely available. Always check the label to confirm viscosity and certifications before purchase.
Maintenance and oil-change considerations
Follow Honda’s maintenance minder system to determine when an oil change is due. Synthetic 0W-20 oil typically allows longer intervals between changes than older conventional oils, but actual timing depends on driving conditions, climate, and usage. If in doubt, err on the side of earlier oil changes to protect the engine.
Summary
For a 2018 Honda CR-V, the recommended oil is 0W-20 synthetic, with API SN or later and ILSAC GF-5/6 specifications. Use Honda Genuine 0W-20 or an equivalent that meets these standards, and follow the maintenance minder to schedule oil changes. Verify the exact requirement in your manual or on the under-hood label, as specifications can vary by market and trim.
