Does the 2009 Lexus ES350 require premium gas?
As a car owner, understanding the type of fuel your vehicle requires is essential for maintaining its performance and longevity. The 2009 Lexus ES350 is a luxury sedan known for its smooth ride and reliable performance, but does it require premium gasoline? Let’s dive into the details to help you make the best decision for your car.
What Does Lexus Recommend?
The 2009 Lexus ES350 is equipped with a 3.5-liter V6 engine that is designed to deliver optimal performance. According to Lexus, this vehicle is recommended to use premium unleaded gasoline with an octane rating of 91 or higher. This recommendation is based on the engine's design, which is tuned to perform best with higher-octane fuel.
Can You Use Regular Gasoline?
While premium gasoline is recommended, the 2009 Lexus ES350 can technically run on regular unleaded gasoline (87 octane). However, there are some important considerations to keep in mind:
- Performance Impact: Using regular gasoline may result in reduced engine performance, as the engine's timing and fuel injection systems are optimized for higher-octane fuel.
- Fuel Efficiency: You may notice a slight decrease in fuel efficiency when using regular gas, which could offset the cost savings at the pump.
- Engine Longevity: Prolonged use of lower-octane fuel could lead to engine knocking or pinging, which may cause long-term damage to the engine.
Why Does Octane Rating Matter?
Octane rating measures a fuel's ability to resist knocking during combustion. High-performance engines, like the one in the 2009 Lexus ES350, are designed to operate at higher compression ratios, which require higher-octane fuel to prevent knocking. Using the recommended fuel ensures that your engine runs smoothly and efficiently.

What happens if I don't use premium gas in my Lexus?
If you use regular gas, the high-compression engine may become more likely to detonate. While one fill-up with regular gas isn't expected to cause long-term damage, this repeated habit can lead to the need of severe repairs or an entire engine replacement.
Is it worth putting 91 instead of 87?
Does Premium Fuel Make Your Car Run Better? Some drivers swear that using a higher-octane fuel is better for a car's performance, but it's not. Engine computers can usually adjust their timing to account for the increased octane levels, so if you put premium gas in a regular car, you probably won't notice anything.
Which Lexus models do not require premium gas?
A luxury vehicle like Lexus may need premium fuel, but the answer to these questions is actually model-specific. Some vehicles, like the Lexus UX 250h, can utilize regular 87-octane fuel, whereas other models, like the 2022 Lexus GX, require premium 91-octane fuel, so the Lexus gas type depends on the model.
What happens if you accidentally put 87 instead of 91 in a Lexus?
If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you'll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.
