Does the Lexus Nx 250 require premium gas?
The Lexus NX 250 is a compact luxury SUV that does not require premium gasoline. According to the manufacturer's recommendations, the NX 250 can run on regular unleaded fuel with an octane rating of 87 or higher.
Fuel Requirements for the Lexus NX 250
The Lexus NX 250 is powered by a 2.5-liter four-cylinder engine that is designed to operate on regular unleaded gasoline. Lexus specifically recommends using fuel with an octane rating of 87 or higher for this model.
While premium fuel (91 octane or higher) is not required, Lexus does state that using premium fuel can improve performance and fuel economy slightly. However, the difference is minimal, and regular 87 octane fuel is perfectly suitable for normal driving.
Reasons to Use Regular Fuel
- Lower fuel costs: Regular gasoline is typically 20-30 cents per gallon cheaper than premium.
- No performance loss: The NX 250's engine is designed to run on regular fuel without any significant loss of power or acceleration.
- Manufacturer recommendation: Lexus specifically states that regular 87 octane fuel is acceptable for the NX 250.
Unless you plan to regularly drive the NX 250 in a very aggressive manner, there is no need to pay the premium for higher octane fuel. Regular 87 octane gasoline will provide the optimal balance of performance and fuel economy for most driving conditions.
When to Consider Premium Fuel
- Towing heavy loads: If you frequently tow heavy trailers or haul large payloads, using premium fuel may provide a slight boost in power and performance.
- High-performance driving: For spirited driving on winding roads or the racetrack, premium fuel can help prevent engine knocking and improve acceleration.
- Older engines: Vehicles with higher mileage or older engine designs may benefit more from the increased octane of premium fuel to prevent pre-ignition and engine damage.
However, for the average Lexus NX 250 owner who uses the vehicle for daily commuting and light hauling, regular 87 octane gasoline is the recommended and most cost-effective fuel choice.
