Does the 2017 Lexus NX 200t require premium gas?
Fuel requirements for the NX 200t
Premium versus regular gasoline
The owner's manual specifies premium unleaded gasoline as the recommended fuel for the NX 200t’s turbocharged engine. The recommended octane rating is 91 AKI or higher, though octane labeling varies by market (AKI in North America, RON in many other regions). Regular 87 octane gasoline can be used if premium is unavailable, but performance, throttle response, and fuel economy may decline when the engine operates under boost.
- Recommended fuel: Premium unleaded gasoline with an octane rating of 91 AKI or higher to support turbo performance and engine protection.
- Alternative fuel: Regular unleaded gasoline (87 octane) can be used if premium is not available, but you may experience reduced acceleration and poorer fuel economy, especially under heavy load.
- Market notes: Octane labeling differs by region (AKI in the U.S./Canada, RON elsewhere). When in doubt, follow the octane rating specified for your market in the owner's manual.
In short, premium gas is the intended fuel for the NX 200t to preserve performance and efficiency. If you must use regular gasoline, anticipate a drop in power and responsiveness, particularly during spirited driving or hot conditions.
Practical fueling guidance
To help owners make informed fueling decisions, consider the following guidelines:
- Check the fuel label and choose the octane rating recommended for your region.
- When possible, use premium gasoline to maximize turbo response and avoid potential knock under boost.
- If you only have access to regular gasoline, avoid heavy acceleration and keep an eye on engine performance, especially in warm weather or when the engine is under load.
For most NX 200t drivers, sticking with premium gasoline provides the best balance of performance, efficiency, and reliability.
Summary
The 2017 Lexus NX 200t benefits from premium gas, with Lexus recommending 91 AKI or higher for optimal performance. Regular gasoline can be used in a pinch, but it may reduce power and fuel economy, particularly under boost or harsh driving conditions. In practice, using premium gas ensures the turbocharged engine delivers the intended acceleration and efficiency.
