Consequences of Using the Wrong Fuel
- Using a lower-octane fuel, such as regular unleaded (87 octane), can lead to engine knocking or pinging, which can cause damage to the engine over time.
- Lower-octane fuel may also result in a noticeable decrease in engine power and acceleration, as well as reduced fuel efficiency.
- In some cases, using the wrong fuel type can trigger the vehicle's engine management system to enter a "limp mode" to protect the engine, further reducing performance.
- Continued use of the wrong fuel type can eventually lead to more serious engine problems, such as increased wear on internal components, reduced engine life, and potentially costly repairs.
It is important for 2014 Lexus IS250 owners to always use the recommended premium unleaded gasoline to ensure their vehicle's optimal performance, fuel efficiency, and long-term reliability.
