Frequently Asked Questions

Why is an oil change important for a 2019 Toyota Mirai?

• The 2019 Toyota Mirai is a hydrogen fuel cell vehicle and does not rely on a conventional internal combustion engine; however, proper lubrication and fluid maintenance for the transaxle, cooling systems, and ancillary components remain essential to long-term reliability.
• Regular fluid inspections and scheduled service keep drivetrain components cool and reduce wear, helping maintain performance and preserving fuel cell and electric drivetrain efficiency.
• Certified dealers use Toyota-approved fluids and procedures tailored to the Mirai’s unique systems, protecting components and the vehicle’s resale value.
• Timely maintenance prevents minor issues from becoming costly repairs, delivering immediate and long-term savings when performed by a trained service team.
• Any repairs or fluid replacements covered under warranty must be performed at a certified dealership to preserve warranty coverage and ensure correct parts and labor.

How long does an 2019 Toyota Mirai oil change take?

• Because the Mirai does not use conventional engine oil, typical service for fluids and inspections is often quicker than a traditional oil change; many routine fluid checks or top-offs can be completed in about 30–60 minutes.
• More comprehensive fluid replacements or transaxle service may take longer—often up to 90 minutes or more—depending on the exact service required and any additional inspections.
