How big is the gas tank on a 1986 Toyota MR2?

The gas tank in the 1986 Toyota MR2 is about 50 liters (roughly 13.2 US gallons).


In detail, the first-generation MR2 (AW11) uses a compact, mid-engine fuel cell designed to balance weight, space, and performance. Official specifications commonly cite around 50 liters of capacity, with only minor variations by market or production revision. For precise figures on a specific car, consult the vehicle’s data plate, owner’s manual, or a Toyota service manual.


Official capacity and typical figures


Toyota’s specification references for the AW11 era regularly list a fuel tank capacity of about 50 liters (approximately 13.2 US gallons). This figure is echoed across many period brochures, owner manuals, and service sheets for the 1986–1989 MR2 models, particularly in US and European markets.


Market variations and practical context


While the tank size is largely consistent across the 1986 MR2 lineup, there are small regional differences due to measurement conventions and minor engineering revisions. In practice, most AW11s share a fuel capacity near 50 liters, with the vast majority falling within a few liters of that figure. If you’re restoring a specific car or verifying a purchase, check the data plate near the fuel filler neck or consult the exact manual for that chassis.


How to verify your car’s exact capacity


To confirm the precise tank capacity for your particular 1986 MR2, use these steps: check the owner’s manual or service manual for the exact specification; read the data plate located in or near the fuel filler area; and if needed, contact a Toyota dealer or classic Toyota archive with your VIN for the exact figure tied to your chassis.


Summary


The 1986 Toyota MR2’s fuel tank is typically listed at about 50 liters (13.2 US gallons). While this value is broadly consistent across first-generation MR2s, small regional or revision-based variations can occur. For exact figures on a given vehicle, consult the data plate, owner’s manual, or a Toyota service resource.

How much is a 1986 Toyota MR2 worth?


The price for a 1986 Toyota MR2 varies widely, with prices typically ranging from about $4,150 to over $22,000, depending on condition, mileage, and rarity. A good, average example can be expected to cost around $12,000, while well-maintained, low-mileage examples can command prices closer to $17,000–$22,000, and those needing significant work can sell for under $5,000.
 
Price factors

  • Condition: The most significant factor. A well-maintained, rust-free, and highly original car will be worth much more than a project car that needs extensive repairs. 
  • Mileage: Lower mileage, especially on the original drivetrain, increases the value significantly. 
  • Rarity and history: Cars with a detailed maintenance history or desirable original features will fetch higher prices. 
  • Market: Prices can differ based on your geographic location and the current market demand. 

Price ranges
  • Low: In the recent past, the lowest auction sale was around $4,150 for a car with significant maintenance needs. 
  • Average: A good, average-condition car is often valued around $12,000. 
  • High: For exceptional, low-mileage, or rare examples, prices can reach $22,000 or more at auction. 



How many miles per gallon does a 1986 Toyota MR2 get?


The 1986 Toyota MR2's MPG varies by model; the supercharged version gets a combined 25 mpg, while the naturally aspirated model can achieve 29 mpg in the city and 34 mpg on the highway when properly tuned. Factors like engine maintenance, driving style, and vehicle modifications can significantly affect the actual fuel economy.

1986 Toyota MR2 MPG by model 

  • Supercharged: Approximately 25 mpg combined. 
  • Naturally Aspirated: Around 29 mpg city / 34 mpg highway, with potential to get higher on the highway. 

Factors that affect MPG
  • Engine Maintenance: A poorly maintained engine can lead to poor fuel economy. Issues like vacuum leaks or a failing oxygen sensor can negatively impact mileage without necessarily triggering a check engine light. 
  • Driving Habits: Aggressive driving will reduce MPG, while a more conservative driving style will improve it. 
  • Modifications: Aftermarket modifications, such as a bike carb conversion, can significantly impact fuel efficiency. While some conversions might achieve a decent MPG, they are not recommended for daily drivers due to the potential for worse fuel economy compared to a stock engine. 
  • Vehicle Condition: Ensuring the engine is properly tuned and components like the cold start injector are working correctly is essential for optimal performance and efficiency.
