What type of oil does an 2021 Toyota Mirai take?

• Nalley Toyota of Roswell uses only factory-approved fluids and parts to meet Toyota specifications and protect vehicle systems.
• If a particular lubricant or fluid change is required, our technicians will reference Toyota service documentation and apply the correct product to preserve performance and warranty coverage.

How much oil does an 2021 Toyota Mirai need?

• Because the Mirai utilizes a fuel cell and electric drive arrangement, there is no standard engine-oil capacity to quote as you would for an internal-combustion vehicle.
• Any required fluid volumes (for cooling systems, reduction gear lubrication, or other services) are specified in the Toyota service manual and are handled precisely by our technicians.
• Nalley Toyota of Roswell will confirm exact fluid requirements and volumes for your vehicle and provide a transparent estimate before performing service.
• Using the correct fluid types and volumes at a certified dealership preserves performance and warranty coverage, delivering better value over time.
