Is 250 Lexus fuel consumption?
In short, the Lexus IS 250 typically returns about 23–25 miles per gallon combined, with variations based on model year and drivetrain. Always check the exact EPA rating for your specific vehicle to know its official fuel economy.
The IS 250, powered by a 2.5-liter V6, was offered in rear-wheel-drive and all-wheel-drive configurations over many years. While it remains a solid performer in the luxury-sedan class, its fuel economy is generally lower than many modern turbocharged fours or hybrids. This article explains typical efficiency ranges, what influences those numbers, and practical tips to maximize real-world mileage.
How fuel economy is measured for the IS 250
EPA ratings explained
Fuel economy figures come from the Environmental Protection Agency (EPA) and cover city and highway driving, plus a combined estimate. Drivetrain (RWD vs. AWD), transmission, and model year can shift these numbers by a few miles per gallon.

Drivetrain differences and typical ranges
Before diving into numbers, note that rear-wheel-drive (RWD) and all-wheel-drive (AWD) IS 250s behave differently at the pump. The figures below are representative ranges for common configurations and may vary by year, tire size, and transmission.
- Rear-wheel-drive IS 250 with automatic transmission: roughly 21–23 mpg in the city, 28–29 mpg on the highway, for a combined of about 23–25 mpg.
- All-wheel-drive IS 250 with automatic transmission: roughly 19–21 mpg in the city, 26–28 mpg on the highway, for a combined of about 23–24 mpg.
Note: Early 2006–2008 models tended to cluster in the low-to-mid 20s combined, while later years generally held in the mid-20s for RWD and slightly lower for AWD. Real-world results depend on driving style and maintenance.
Real-world driving and optimization tips
Practical steps to improve mpg
Actual mileage often differs from the EPA numbers due to aggressive driving, climate control use, and trip types. The following tips help maximize efficiency in everyday driving.
- Keep tires inflated to the manufacturer’s recommended pressure; under-inflated tires reduce fuel economy and handling.
- Drive smoothly with gradual acceleration and anticipation of stops to minimize unnecessary braking and throttle changes.
- Follow the maintenance schedule—regular oil changes, air filter replacements, and spark plug checks help sustain efficiency.
- Use the recommended fuel grade and avoid excessive idling; premium gasoline is typically recommended for the IS 250’s V6 for optimal performance and efficiency.
- Lighten the load: remove unnecessary weight and avoid roof racks or carriers on longer highway trips.
- When possible, use cruise control on highways to maintain steady speeds and improve average mpg.
By applying these practices, real-world mileage on an IS 250 can approach the higher end of its typical range, though it’s unlikely to match the efficiency of newer lightweight turbo-four or hybrid rivals.
Is the IS 250 still a practical choice for fuel economy?
Today the IS 250 is largely out of new-vehicle production in most markets, with Lexus focusing on newer IS models powered by turbocharged four-cylinder engines or V6 options in the IS 350 lineup. If fuel economy is a priority, consider newer IS variants, hybrids, or competing luxury sedans with more advanced efficiency tech. For used-car buyers, the IS 250 can still offer reasonable fuel economy for its age, provided it has been well maintained.
Summary
The Lexus IS 250 delivers mid-20s fuel economy in typical driving, with clear differences between RWD and AWD configurations and across model years. For precise numbers, consult your vehicle’s EPA rating and owner’s manual. Real-world mileage benefits from steady driving, proper maintenance, and mindful load management. As today’s lineup leans toward turbocharged and hybrid options, the IS 250 remains a solid used choice for value and performance, but not primarily for top-tier fuel efficiency.
Does a Lexus IS 250 need premium gas?
Yes, the Lexus IS250 recommends premium unleaded gasoline (91 octane or higher) for optimal performance and to prevent engine knocking. While using a lower-octane fuel like regular 87 octane won't cause immediate, catastrophic damage, it may lead to engine knocking and reduced performance over time, and can contribute to faster carbon buildup on engine parts.
Recommended action
- Use premium gasoline: For the best engine performance, efficiency, and longevity, use 91 octane or higher.
- Use regular sparingly: If you must use 87 octane, it's best to do so only in a pinch and to return to premium as soon as possible to avoid potential issues.
- Be aware of performance impact: The engine computer will adjust, but you may notice reduced performance when using lower-octane fuel.
- Prevent long-term damage: Consistent use of lower-octane fuel can lead to persistent engine knocking, which can cause long-term engine damage.
Is the Lexus IS250 engine reliable?
The reliability has been nothing short of incredible - no problems in nearly 20000 miles of driving on some pretty awful roads. No bulb failures at all! The 2.5 litre engine is well-known to burn a little oil, so I check the oil level on a weekly basis. I drive thousands of miles between top-ups, by the way.
Is 250 Lexus 2008 fuel consumption?
Lexus IS250 2008 Fuel consumption
