Most 2018 Nissan models with four-cylinder engines require 0W-20 synthetic motor oil, and many with V6 engines follow the same spec, but the exact grade depends on the model and engine. Always verify with the owner's manual or the under-hood oil cap to avoid using the wrong grade.
How to determine the exact oil type for your 2018 Nissan
The following steps help you confirm the correct oil grade for your specific 2018 Nissan model. Because Nissan variants vary by engine, using the right viscosity and specification protects the engine and maintains warranty coverage.
- Check the owner's manual for the exact viscosity (for example 0W-20) and the API/ILSAC specification required by your engine.
- Look at the Oil Filler Cap on the engine; many 2018 Nissan engines mark the recommended grade (often 0W-20) on the cap.
- Identify your engine code or model lineup (for instance, 2.5L four-cylinder vs. 3.5L V6) to cross-check with Nissan's official documentation for your VIN.
- If you still can't confirm, contact a Nissan dealer or a qualified mechanic who can look up your specific VIN.
Note: In general, Nissan's 2018 lineup commonly uses 0W-20 full synthetic oil, but some models or special editions may differ. Always rely on official documentation for your vehicle.
Why using the correct oil matters
The correct oil maintains lubrication, fuel economy, and engine protection. Using the wrong viscosity can affect performance and warranty coverage.
Maintenance tips
Plan to change oil every 5,000 to 7,500 miles or as recommended by Nissan for your driving conditions and model; use a reputable brand that meets ILSAC GF-5 or GF-6 and API SN or newer standards.
Summary
For most 2018 Nissan vehicles, the recommended oil is 0W-20 synthetic. Verify with your owner's manual, the oil cap, or your Nissan dealer to ensure you have the correct grade for your exact engine and model. Regular oil changes with the right oil help protect the engine and maintain warranty coverage.
