Can you put regular gas in a Toyota Mirai?

No, you should not put regular gasoline in a Toyota Mirai. The Mirai is a hydrogen fuel cell electric vehicle (FCEV) that requires hydrogen fuel, not traditional gasoline, to operate. Putting regular gas in a Mirai would damage the vehicle's fuel system and powertrain.


Understanding the Toyota Mirai and Its Fuel Requirements


The Toyota Mirai is an innovative FCEV that uses hydrogen gas to generate electricity through a fuel cell, which then powers the vehicle's electric motor. Unlike traditional gasoline-powered cars or even battery electric vehicles (BEVs), the Mirai does not use gasoline or plug into an electrical outlet to recharge. Instead, it is refueled with compressed hydrogen gas at specialized hydrogen fueling stations.


The Mirai's fuel cell system is designed to work exclusively with hydrogen fuel. Putting regular gasoline into the Mirai's fuel tank would not provide the necessary chemical reaction to generate electricity and power the vehicle. In fact, introducing gasoline into the Mirai's system could severely damage the sensitive fuel cell stack, hydrogen storage tanks, and other critical components.


Consequences of Using Regular Gas in a Toyota Mirai



  • Damage to the fuel cell stack: Gasoline would contaminate and degrade the fuel cell membrane, reducing its ability to efficiently convert hydrogen into electricity.

  • Clogged hydrogen storage tanks: Gasoline residues could block the flow of hydrogen gas into the fuel cell system.

  • Corrosion of fuel system components: Gasoline's chemical properties could corrode and deteriorate various metal and rubber parts in the Mirai's fuel system.

  • Voided warranty: Using the wrong fuel type would likely void the Mirai's manufacturer warranty, leaving the owner responsible for any resulting repairs or replacements.


In summary, it is critical that Toyota Mirai owners only refuel their vehicles with the specified compressed hydrogen gas. Using regular gasoline would cause significant and irreparable damage to the Mirai's unique fuel cell powertrain.

What are the disadvantages of the Toyota Mirai?


Disappointing Cargo Capacity. The Toyota Mirai needs more cargo and personal item storage, which could be a significant downside for those who need ample space. The trunk offers a limited capacity of just 9.6 cubic feet, which is relatively small for a car of its size.



What is the lifespan of the Toyota Mirai?


approximately 150,000 to 200,000 miles
At the end of their lifespan, these fuel cells are designed for the disassembly and recycling of their materials, similar to the process for other vehicle components. With that said, this means that the Toyota Mirai is expected to have a lifespan of approximately 150,000 to 200,000 miles.



Can you put gas in a Mirai?


The Mirai is a hydrogen-powered fuel cell vehicle that must be fueled at hydrogen stations conforming to the latest Society of Automotive Engineers (SAE) hydrogen fueling interface protocol standards or laws that may supersede such SAE standards.



Where do I fill my hydrogen car?


The list of hydrogen refuelling stations in the UK @ April 2021

  • HyFive 2, Rainham, Essex (RM13 8EU)
  • Sainsbury's, Hendon, London (NW9 6JX)
  • Hatton Cross, London (TW6 2GE)
  • HyFive 1, Teddington, Surrey (TW11 0LY)
  • HyFive 3, M25 Cobham Services, Surrey (KT11 3JS)
  • M40 Beaconsfield Services, Buckinghamshire (HP9 2SE)



Is hydrogen cheaper than gas?


Fueling Costs
While the current price of hydrogen is higher than gasoline, fuel cells are approximately 2.5 times more efficient than gasoline engines. An added bonus is that most fuel cell car manufacturers include three years' worth of free fuel with a vehicle.



Why are used Toyota Mirais so cheap?


There are three good reasons why a used Toyota Mirai is so cheap – the spotty fueling infrastructure, poor Mirai sales, and the high cost of hydrogen after your fuel card is used up.



How long do hydrogen engines last?


LONG ANSWER
The automakers also provide warranties for all key fuel cell components, including the fuel cell stack, compressor, hydrogen Page 16 tanks, battery packs, and fueling control units. The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles.



How far will a Toyota Mirai go on a full tank?


Mirai has an EPA-estimated driving range of 312 miles and an EPA-estimated fuel economy of 67 MPGe.



How long does it take to refill a Toyota Mirai?


approximately 3-5 mins
Refuelling the Toyota Mirai at a commercial station takes approximately 3-5 mins from empty to full.
