How fuel efficient is a 2JZ?
The Toyota 2JZ engine is legendary among car enthusiasts for its durability, power potential, and versatility. However, when it comes to fuel efficiency, the 2JZ engine's performance can vary significantly depending on the specific model, driving conditions, and modifications. In this article, we’ll explore the fuel efficiency of the 2JZ engine and what factors influence it.
Understanding the 2JZ Engine
The 2JZ engine family consists of several variants, including the naturally aspirated 2JZ-GE and the turbocharged 2JZ-GTE. These engines were produced by Toyota in the 1990s and early 2000s and are most famously associated with the Toyota Supra. While they are celebrated for their performance capabilities, fuel efficiency was not their primary design focus.
Fuel Efficiency of the 2JZ Engine
The fuel efficiency of a 2JZ engine depends on the specific variant and how the vehicle is driven. Here’s a general breakdown:
- 2JZ-GE (Naturally Aspirated): This version is more fuel-efficient compared to its turbocharged counterpart. In stock form, it can achieve approximately 18-24 miles per gallon (mpg) in mixed driving conditions. Highway driving may yield closer to 24 mpg, while city driving can drop it to around 18 mpg.
- 2JZ-GTE (Turbocharged): The turbocharged variant is less fuel-efficient due to its higher power output and increased fuel demands. Expect fuel economy in the range of 15-20 mpg, with spirited driving or modifications potentially reducing this further
As the owner of Kevin's Autos, a trusted auto service provider with years of expertise, I'm often asked about the fuel efficiency of various engine models. One engine that has gained a reputation for its impressive performance is the 2JZ, a legendary inline-six powerplant found in numerous high-performance vehicles. In this article, we'll dive into the fuel efficiency of the 2JZ and explore why it has become a favorite among enthusiasts and car owners alike.
The 2JZ Engine: A Brief Overview
The 2JZ engine, developed by Toyota, is a 3.0-liter inline-six engine that has been used in a variety of vehicles, most notably the iconic Toyota Supra. Known for its exceptional reliability, robust construction, and impressive tuning potential, the 2JZ has become a staple in the world of high-performance and enthusiast-driven automobiles.
Fuel Efficiency of the 2JZ
When it comes to fuel efficiency, the 2JZ engine is often praised for its relatively good performance. According to industry data, the 2JZ-equipped Toyota Supra can achieve an average fuel economy of around 20-25 miles per gallon (MPG) in mixed driving conditions. This is quite impressive, considering the engine's high-performance capabilities and the fact that the Supra is a sports car.
The 2JZ's fuel efficiency can be attributed to several factors:
- Efficient Engine Design: The 2JZ's inline-six configuration and advanced engineering contribute to its efficient combustion and power delivery, which helps optimize fuel consumption.
- Lightweight Construction: The 2JZ engine is known for its lightweight design, which reduces the overall weight of the vehicle and improves fuel efficiency.
- Tuning Potential: The 2JZ's reputation for being highly tunable allows owners to optimize the engine's performance and efficiency through various modifications and tuning techniques.
It's important to note that the actual fuel efficiency of a 2JZ-equipped vehicle can vary depending on factors such as driving conditions, driving style, and any modifications made to the engine or vehicle.
Maintaining Fuel Efficiency in 2JZ-Powered Vehicles
To ensure optimal fuel efficiency in a 2JZ-powered vehicle, it's crucial to maintain the engine and follow recommended service intervals. This includes regular oil changes, air filter replacements, and addressing any issues that may arise, such as faulty sensors or worn-out components. By keeping the 2JZ well-maintained, owners can maximize the engine's fuel efficiency and enjoy the best possible driving experience.
In conclusion, the 2JZ engine is renowned for its exceptional performance and reliability, and it also offers relatively good fuel efficiency, especially when compared to other high-performance engines. By understanding the factors that contribute to the 2JZ's fuel efficiency and following proper maintenance practices, owners can enjoy the best of both worlds – thrilling performance and respectable fuel economy.

What is the fuel consumption of 2JZ GE engine?
You have to search for a good piece, as stated by another pakwheeler 2JZ GE gives around 6-8 KM/L in City keeping in mind the heavy body Crown has. To me, the fuel economy is unbearable especially in todays time with petrol being so expensive so not a good daily driver for me.
How many miles per gallon does a 2JZ NAT get?
Average mpg is about 22mpg.
Why is the 2JZ so reliable?
An engine's power comes not just from its output but from its resilience to handle that power reliably. This is where the 2JZ shines with its cast-iron block construction. This sturdy, high-tensile material was designed to handle immense stress and high-compression forces associated with serious tuning and upgrades.
How much HP is a stock 2JZ?
The 2JZ-GTE is based upon a 3.0L, inline-six, cast-iron short-block with an aluminum head. From the factory, North American versions put down 320hp but leave a whole lot of wiggle room for much more.
What is the highest mileage 2JZ?
The fourth-generation Toyota Supra is a legend for numerous reasons, but one of its defining qualities is its reliability. Its 3.0-liter 2JZ straight-six is especially bulletproof, as this Supra, with a claimed 520,000 miles on the clock, can attest. The owner claims the motor has "never been touched" either.
How many miles per gallon does a 2JZ Supra get?
Fuel Economy
City 17 mpg Highway 22 mpg Combined 19 mpg
How many miles do 2JZ engines last?
If the 2JZ isn't screwed with they've been proven to last for 200k+ miles time and time again. They're super popular for the tuner market because they are massively overbuilt so they can handle a ton of extra power. I daily drove my SC for years and the only issues I had were electrical and never had an engine fault.
How much HP can a 2JZ handle?
The 2JZ-GTE's already proven itself worthy of belting out more than 2,000hp. You'll need more than a 64mm turbo to get anywhere close, though, but it's less complicated than you think. Start with something in the 72mm range, and plan on bulking up the bottom end with forged pistons and rods as well as billet main caps.
