How fuel efficient is a 2JZ?
The 2JZ engine, a legendary inline-six powerplant produced by Toyota, is renowned for its exceptional performance and durability. However, one question that often arises is how fuel-efficient this iconic engine is. In this article, we'll dive into the details of the 2JZ's fuel efficiency and explore the factors that contribute to its performance.
The 2JZ Engine: A Brief Overview
The 2JZ engine, first introduced in 1991, is a 3.0-liter inline-six engine that was primarily used in Toyota's high-performance vehicles, such as the Supra and Aristo. The engine's design, which includes features like forged internals and a cast-iron block, has made it a favorite among enthusiasts and tuners alike, known for its ability to withstand high levels of power and modification.
Fuel Efficiency of the 2JZ
When it comes to fuel efficiency, the 2JZ engine performs reasonably well, especially considering its high-performance capabilities. According to manufacturer specifications, the 2JZ-GTE (turbocharged) variant of the engine can achieve a fuel economy of around 18-20 miles per gallon (MPG) in city driving and 24-26 MPG on the highway. This is a respectable figure for a high-performance engine, particularly when compared to modern turbocharged engines that often sacrifice fuel efficiency for increased power.
The 2JZ-GE (naturally aspirated) variant of the engine, on the other hand, is slightly more fuel-efficient, with estimates ranging from 20-22 MPG in the city and 26-28 MPG on the highway. This is due to the lack of a turbocharger, which can add complexity and reduce overall efficiency.
Factors Affecting 2JZ Fuel Efficiency
Several factors can influence the fuel efficiency of the 2JZ engine, including:
- Engine Modifications: Extensive modifications, such as the addition of a turbocharger or other performance upgrades, can impact the engine's fuel efficiency, often resulting in a decrease in MPG.
- Driving Conditions: As with any engine, the 2JZ's fuel efficiency can be affected by driving conditions, such as traffic, terrain, and weather. Aggressive driving, for example, can significantly reduce fuel economy.
- Maintenance: Proper maintenance, including regular oil changes and tune-ups, can help maintain the engine's fuel efficiency over time.
It's important to note that the fuel efficiency figures mentioned above are based on manufacturer specifications and may vary depending on the specific vehicle, driving conditions, and the engine's state of tune.
Conclusion
The 2JZ engine, despite its high-performance capabilities, offers respectable fuel efficiency, especially in its naturally aspirated form. While modifications and driving conditions can impact its MPG, the 2JZ remains a well-balanced engine that can provide both power and efficiency. As with any engine, proper maintenance and driving habits are key to maximizing the 2JZ's fuel economy.
What is the fuel consumption of is300 2JZ?
The Lexus IS 300 currently offers fuel consumption from 9.3 to 9.3L/100km.
Is IS300 good on gas?

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 NAT get?
Average mpg is about 22mpg.
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.
How many miles per gallon does a 2JZ Supra get?
Fuel Economy
| City | 17 mpg |
|---|---|
| Highway | 22 mpg |
| Combined | 19 mpg |
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.
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.
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 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.
