Can you use regular gas on a Lexus 350?
No, you should not use regular gasoline in a Lexus 350. The Lexus 350 requires premium unleaded gasoline with an octane rating of 91 or higher. Using regular gas in a Lexus 350 can cause engine damage and negatively impact the vehicle's performance.
Detailed Explanation
The Lexus 350 is a luxury vehicle that is designed to run on premium fuel. The engine in the Lexus 350 is engineered to take advantage of the higher octane rating of premium gasoline, which helps prevent knocking and pre-ignition. Using regular gasoline, which has a lower octane rating, can cause the engine to experience increased knocking and pre-ignition, leading to potential damage over time.
In addition to the risk of engine damage, using regular gas in a Lexus 350 can also result in a noticeable decrease in performance. The engine may feel less responsive, and you may experience a reduction in fuel efficiency. This is because the engine is not able to operate at its optimal performance level when using a lower octane fuel.
Recommendations
- Always use premium unleaded gasoline with an octane rating of 91 or higher in your Lexus 350.
- Avoid using regular gasoline, as it can cause engine damage and reduce performance.
- Check your owner's manual for the recommended fuel type and octane rating for your Lexus 350.
- If you accidentally use regular gas, it's best to fill up with premium fuel as soon as possible to minimize any potential damage.
Following the manufacturer's recommendations for fuel type is important for maintaining the health and performance of your Lexus 350. Using the correct premium fuel will help ensure your vehicle runs at its best and lasts for many years to come.
Which Lexus can run on regular gas?
Several Lexus models use regular 87-octane gasoline, including the Lexus ES (e.g., ES 250, ES 350, ES 300h) and the UX 250h. Some NX models like the NX 250 (for example, the 2024 and 2025 models) also use regular gas. It is essential to check your specific model's owner's manual for the correct fuel recommendation.
Models that use regular gas
- Lexus ES: Models like the ES 250, ES 350, and ES 300h are designed to run on 87-octane regular gasoline.
- Lexus UX: The UX 250h, such as the 2024 model, uses regular gas.
- Lexus NX: Some NX models, such as the 250, use 87-octane regular fuel.
Important considerations
- Consult your owner's manual: The most accurate information for your specific vehicle will always be in the owner's manual.
- Premium is required for some models: Many other Lexus models, especially performance-oriented or turbocharged ones like the IS, GS, LS, and some RX, RC, and LX versions, require a minimum of 91-octane premium fuel.
- Consequences of using the wrong fuel: Putting regular gas in a car that requires premium can potentially cause engine damage over time.
