What is the gas mileage on a Lexus IS300 2JZ?
The Lexus IS300, produced from the early 2000s, uses the 2JZ-GE 3.0-liter inline-six. In typical specifications, the automatic version averages about 20 mpg in the city and around 26–27 mpg on the highway, while the 5-speed manual tends to be around 19–20 mpg in the city and about 25–27 mpg on the highway. Real-world results vary based on year, condition, and driving style.
EPA estimates by drivetrain
The following figures reflect EPA estimates from the 2001–2005 IS300 models and can vary slightly by year, tire size, and transmission choice.
- Automatic transmission: roughly 20 mpg city and 26–27 mpg highway.
- Manual transmission: roughly 19–20 mpg city and 25–27 mpg highway.
These numbers provide a baseline for expected fuel economy, though individual results may differ depending on maintenance and driving conditions.
Real-world performance
Actual mileage often diverges from EPA estimates, especially in city driving with frequent stops, aggressive acceleration, or aging components. The IS300’s weight and gearing also influence efficiency, particularly as the vehicle wears over time.
- City driving: commonly between 15–22 mpg, depending on traffic, driving style, and engine wear.
- Highway driving: typically in the mid-20s to upper-20s mpg, with steady speeds and well-maintained engines achieving around 26–29 mpg.
For best results, ensure regular maintenance (air filters, spark plugs, oil changes) and keep tires properly inflated to maximize mpg for this age‑dated performance sedan.
Factors that affect mpg and how to maximize it
Fuel economy in an IS300 with a 2JZ-GE is influenced by maintenance history, tire condition, alignment, and driving style. Gentle acceleration, steady speeds, and minimizing idling can noticeably improve mpg on older vehicles like this.
Summary: The IS300’s fuel economy sits in the low 20s mpg in city and upper 20s mpg on highways depending on transmission and condition. Automatic versions are typically around 20/26–27 mpg, while manuals run about 19–20 mpg city and 25–27 mpg highway. Real-world results vary with wear, maintenance, and driving habits.
IS300 good on gas?
During the winter, I seem to hover right around 20mpg combined (in normal mode). In the summer, closer to 25, but on road trips, I can break 30mpg pretty easily in Eco mode. It's all in how you drive. For BEST results, use non-ethanol gas, and add a can of Royal Purple Octane Booster at each full-up…
