Frequently Asked Questions

Why is an oil change important for a 2023 Toyota Mirai?

• Although the 2023 Toyota Mirai uses a hydrogen fuel cell and an electric drivetrain rather than a traditional internal combustion engine, certain drivetrain components and accessory gearboxes still require proper lubrication to operate smoothly and last longer.
• Regular fluid inspections and oil service help prevent premature wear, reduce friction, and protect seals and bearings — extending component life and avoiding costly repairs down the road.
• Timely service preserves efficiency and range by ensuring systems that rely on lubrication perform optimally, delivering the immediate and long-term savings that come from fewer breakdowns and better fuel (hydrogen/electric) economy.
• Any warranty-covered repairs or services must be performed at a certified dealership to remain eligible under Toyota’s warranty terms; Herb Chambers Toyota of Boston uses factory-trained technicians and OEM fluids to protect that coverage.

How often should you get an oil change for a 2023 Toyota Mirai?

• Follow the schedule in your owner’s manual for specific intervals — the Mirai’s fuel cell and electric drivetrain have different maintenance needs than a gasoline vehicle, and Toyota’s guidelines should be followed for optimal performance.

• Herb Chambers Toyota of Boston recommends using manufacturer-specified intervals and will notify you of required services during each visit to help maximize the vehicle’s lifetime value and reduce long-term ownership costs.

What type of oil does a 2023 Toyota Mirai take?

• The 2023 Toyota Mirai uses manufacturer-specified fluids and lubricants for any components that require oil; where applicable, Toyota-approved synthetic oils and OEM fluids are used to meet engineering specifications.
• Herb Chambers Toyota of Boston uses only OEM-approved fluids and parts so systems perform as designed and warranty conditions remain intact.
• If you’re unsure which fluid the Mirai requires, our certified technicians will verify the correct specification and apply the right product during service.

How much oil does a 2023 Toyota Mirai need?

• Oil volumes vary by system; because the Mirai’s design differs from a conventional gasoline vehicle, exact quantities depend on the component being serviced.
• Our technicians reference the factory specifications and measure to fill precisely to spec — this ensures optimal lubrication and prevents overfilling or underfilling that can harm components.
• For a precise capacity or estimate, contact Herb Chambers Toyota of Boston or bring your vehicle in for an inspection; any warranty-covered service must be completed here or at another certified Toyota dealership to retain coverage.
