Frequently Asked Questions

Why is an oil change important for a 2020 Toyota Mirai?

• The 2020 Toyota Mirai is a fuel-cell electric vehicle and does not require a traditional internal-combustion engine oil change; however, proper lubrication and scheduled fluid services for the drive unit, reduction gear, and cooling systems are essential to reduce wear, prevent corrosion, and maintain efficiency.
• Regular fluid and system checks protect fuel cell components and electric drive parts, ensuring consistent hydrogen system performance, avoiding costly failures, and preserving range and responsiveness over time.
• Having these services performed at Herb Chambers Toyota of Boston delivers immediate and long-term savings: factory-recommended fluids, precise service intervals, and diagnostic checks reduce repeat repairs and help maintain resale value.
• Any repairs or fluid services covered under warranty must be completed at a certified dealership; our factory-trained technicians document work to protect your coverage and ensure compliance with Toyota standards.

How long does a 2020 Toyota Mirai oil change take?

• Because the Mirai does not use conventional engine oil, a standard oil-change time does not apply; typical scheduled fluid services or drive-unit inspections at our dealership are completed efficiently, often within an hour to two hours depending on the service scope.
• More involved procedures—such as reduction-gear fluid replacement, coolant service for the fuel cell stack, or additional diagnostics—may require more time; our service advisors provide an accurate time estimate when you schedule.
• At Herb Chambers Toyota of Boston we prioritize quick turnarounds and transparent timing, which yields immediate savings in time and convenience compared with repeat or incomplete repairs from non-certified providers.
• For warranty-covered work, scheduling at a certified dealership ensures correct parts and procedures are used; this avoids delays that can arise when returning a vehicle to address issues from non-certified service.
