How many miles can the GR86 go?

On a full tank, the GR86 typically travels about 290 to 340 miles, depending on transmission, driving style, and conditions.


The question hinges on two key figures: how much fuel the car can hold and how efficiently it uses that fuel. Different model years and transmissions affect the exact numbers. Below is a detail-oriented look at how range is determined and what you can expect in real-world driving.


Range basics


Fuel tank size


GR86 fuel tank capacity is about 12.3 gallons in most recent models (roughly 46.5 liters). Exact capacity can vary slightly by year and trim.


Fuel economy estimates


EPA-rated fuel economy for GR86 typically falls around 21–21 mpg city and 27–28 mpg highway, with a combined mpg in the low 23s to mid-24s. Manual transmissions often yield slightly lower city mpg than automatics, while highway mpg tends to be similar. Real-world results depend on driving style, terrain, and conditions.


Estimated driving range by configuration


Below are typical ranges for common GR86 setups. These estimates use a 12.3‑gallon tank and EPA-style efficiency figures; real-world results vary.



  • Manual transmission, mixed driving: approximately 280–290 miles

  • Automatic transmission, mixed driving: approximately 290–305 miles

  • Highway-focused driving: up to about 340–345 miles


Note: These ranges assume a full tank and typical driving conditions. Real-world range can be higher or lower based on speed, load, altitude, and weather.


Tips to maximize range


To stretch the GR86’s range per tank, consider the following practical steps:



  • Maintain a steady speed and anticipate traffic to avoid frequent braking and acceleration

  • Use cruise control on highways when safe to keep a steady pace

  • Keep tires inflated to the recommended pressure for optimal efficiency

  • Limit roof rack usage and reduce weight inside the car when possible

  • Warm up the engine efficiently and minimize idling with accessories on


Even with careful driving, range will vary with weather, terrain, and fuel quality. Always plan for a margin in longer trips.


Summary


In practical terms, most GR86 models will cover roughly 290–340 miles on a full tank, with the exact figure influenced by transmission choice, driving style, and road conditions. For precise numbers, refer to the vehicle’s door sticker for tank capacity and the latest EPA fuel economy ratings, and adjust expectations based on your own driving habits.

Can a Toyota last 500,000 miles?


Yes, a Toyota can last 500,000 miles with proper care and maintenance. While the average Toyota lifespan is 200,000-250,000 miles, consistent upkeep, such as regular oil changes, timely fluid replacements, and other preventative maintenance, significantly increases the chances of reaching the 500,000-mile mark. 
Key factors for longevity

  • Consistent maintenance: Following the manufacturer's maintenance schedule for services like oil, transmission fluid, and coolant changes is crucial.
  • Fluid care: Timely replacement of all fluids, including engine oil, transmission fluid, coolant, brake fluid, and power steering fluid, is essential for longevity.
  • Proactive repairs: Addressing small issues, like leaks or a check engine light, promptly can prevent minor problems from becoming major, costly repairs.
  • Driving habits: Gentle driving, including avoiding hard braking and warming up the engine slowly, can help the vehicle last longer.
  • Regular inspections: Routinely checking and replacing parts like filters and the serpentine belt, as well as performing annual wheel alignment checks, helps prevent failures. 



Can an engine last 300,000 miles?


On average, most car engines are designed to last between 150,000 to 200,000 miles. However, with the right care, many engines can last much longer, even up to 300,000 miles or more. In fact, there are numerous stories of vehicles reaching the 500,000-mile mark with their original engine still intact.



How long does a Toyota GR86 last?


A Toyota GR86 can last anywhere from 150,000 to over 200,000 miles with proper maintenance, though this can vary significantly based on how the car is driven. Consistent oil changes, using quality parts, and following the manufacturer's service schedule are key to achieving a long lifespan. Some owners have reported reaching 100,000 miles or more, while others have encountered issues, especially with hard track use. 
Factors affecting longevity

  • Maintenance: Regular oil changes (every 3,500–5,000 miles is recommended) and other scheduled maintenance are crucial. 
  • Driving style: Driving the car aggressively, especially on a track, can increase the risk of engine issues. The engine can be particularly vulnerable to oil starvation under heavy track use. 
  • Modifications: While many owners modify their cars without issue, there are concerns that certain modifications could lead to reliability problems. 
  • Factory issues: There have been reports of excessive RTV silicone from the factory that could clog oil passages and cause engine damage, particularly for cars used for track events. Cleaning out excess RTV is a common preventative measure recommended by some owners. 

How to maximize your GR86's lifespan
  • Follow the maintenance schedule: Adhere to Toyota's recommended service intervals. 
  • Use quality parts: Use OEM oil and filters (like the OEM Subaru Black Filter) to ensure the best performance and protection. 
  • Allow the engine to warm up: Drive for 20–25 minutes to allow all components to reach their operating temperature before driving hard. 
  • Be mindful of track use: If you plan to track your car, consider getting the oil pan checked for excess RTV and consider an oil baffle plate to prevent oil starvation. 
  • Document issues: Keep records of any repairs or maintenance performed on the vehicle, especially if you plan to sell it later.



Is the GR86 a reliable car?


As a whole, consumers found the vehicle's reliability and styling to be its strongest features and performance to be its weakest. 7 out of 10 of owners (70% of them) rank the 2024 GR86 five out of five stars.
