What Happens If I Use Premium Gas In My Lexus ES 350?
Since your 2022 Lexus ES 350 is a luxury car and is designed to run on either premium or standard gas with an octane rating of 87 or 91, premium gas can help highlight the features that you want to stand out about your car. You have complete freedom to choose.
For more details on the suggested usage of either premium or ordinary gas and its requirements, we advise reading your Owner’s Manual.
A 2015 Lexus ES350, does it need premium fuel?
No, you are not required to use premium petrol. You are free to use mid-grade, but never regular, when driving a high-performance luxury car. With premium petrol, you will experience higher performance and MPG.
Can normal gas be used in a Lexus IS 350?
Don’t worry if you accidently fill up with regular fuel; just keep driving as usual and use premium fuel when you fill up again.
For its performance vehicles, such the coupes, as well as the more upscale sedans and SUVs in its inventory, Lexus calls for high octane fuel.
These cars’ high compression engines may have problems if you fill them up with fuel of a lower octane.
When an engine has a high compression ratio, more gasoline and air are crammed into the cylinder than when an engine has a low compression ratio, according to Jalopnik.
Your car’s performance and fuel economy will deteriorate if you continue to use ordinary gas. Even worse, conventional gas increases the likelihood of long-term problems with your car’s engine.
What happens if I don’t fill up my Lexus with premium fuel?
If a Lexus model needs premium, it signifies that the car manufacturer designed the engine to run on high-octane fuel. Regular gasoline, which has a lower octane level, raises the possibility of uncontrolled self-combustion, which can result in engine banging.
Fortunately, not all Lexus vehicles require premium fuel to function properly. Depending on what the automaker demands, premium gas may or may not be used.
What occurs though if you continue to use standard petrol even when the automaker demands premium fuel?
For its high performance vehicles, such the coupes, Lexus demands high octane fuel. These vehicles’ high compression engines run on lower octane gas and are prone to detonation. Fortunately, modern computers can modify your car’s ignition system so that it only operates on conventional gas up to a certain degree.
Your car’s performance and fuel economy will deteriorate if you continue to use ordinary gas. Even worse, normal gas increases the likelihood of a detonation in your car’s engine.
The basic line is that you should not use standard gas if Lexus specifies premium fuel or at least fuel with an octane value of 91. You invalidate your warranty if you use normal petrol and your engine gets damaged. This implies that you will be responsible for the damages, which may exceed the money you would have saved by using standard gas.
Will 87 octane gas work in my Lexus?
Only unleaded fuel with an octane level of 87 or higher is permitted in the RX. As the premium octane rating is 91 or higher, the Lexus RX does not require premium fuel. Of course, you are welcome to fill up your Lexus RX with premium fuel if you want better performance, but it is not necessary.
Which Lexus models are fuel-efficient?
- Use 91 octane for an NX, RX hybrid, GX, and LX, it is advised (premium fuel).
- RX, NX Hybrid, and UX (regular or hybrid) all require 87 octane (regular fuel)

What occurs if normal fuel is used in a high-end vehicle?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
91 or higher posted octane premium unleaded gasoline should be used. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
Are Lexus repairs expensive?
In comparison, maintenance and repairs are affordable because Lexus is Toyota’s premium arm. For its low ownership expenses, Lexus received an overall ranking from RepairPal of sixth. Owners of Lexus automobiles pay $551 on maintenance and repairs annually, while expenses rise as cars get older.

The most well-known providers were assessed, and we chose a few that stood out above the others. All of our suggestions for third-party extended auto warranties scored highly in terms of features, plan alternatives, industry reputation, and customer support.
What happens if you round down to 87 from 91?
Do not become alarmed if the manufacturer of your automobile or truck suggests premium fuel for your vehicle but you instead use normal. Even though premium is advised, you are not required to use it; the engine can run just as well on standard gas.
You can run into issues if you use standard fuel when your manufacturer calls for premium. How well your car or truck will handle normal petrol depends on the sophistication of your fuel system as well as other elements like how your engine is tuned, what the timing is, and how hot it runs. Most of the time, the car will run just fine, although you might notice less power and reduced gas mileage. Because the fuel isn’t burning properly in more acute cases, you might hear engine banging or valve chatter. You should take it to your mechanic because these things might harm your engine.
Can 87 and 91 gas be combined?
Yes, drivers are allowed to mix the two fuel kinds. According to The Drive, the mixture of gas types will produce an octane level somewhere in the center, which the vehicle “will survive.
Is premium fuel truly required?
Some high performance and luxury automobiles need premium gas, which is defined as gas having an octane value of 91 or higher. High octane gasoline has a harder time igniting, which helps high performance engines avoid pre-ignition and knocking. If you frequently fill up with ordinary when your vehicle needs premium fuel, the engine could become damaged.
Do I need premium petrol for my 2011 Lexus ES 350?
The Lexus ES 350 enters the 2011 model year using normal fuel that has an octane rating of 87 after receiving amenity upgrades and styling improvements the previous year.
What type of gas is used in a 2009 Lexus ES350?
HI CAR TALK, My Lexus ES350 from 2009 was recently sold. It required premium unleaded fuel, and I never had any issues with it (it was clearly indicated on the fuel cap). I purchased a 2019 Lexus ES350 in March. The dealer advised me to use standard unleaded gasoline (also noted on fuel cap).
Can I fill up my Lexus with 89 gas?
This query is frequently asked, particularly in light of the current fuel shortages. Every model from Lexus is intended to run on unleaded fuel, but the minimum octane rating varies by model and, for select Lexus models, by year. The list of current models that just require normal unleaded fuel with an octane of 87 is shown below. The list of Lexus models has a requirement for premium unleaded fuel with an octane of 91. If your vehicle requires 91 octane but you can’t find a gas station that has premium unleaded fuel, don’t get upset. Your vehicle will function properly if you use fuel with a lower rating as long as it is unleaded. Fill up now so you can travel where you need to go, and when you need gas againor as soon as your preferred station offers itcontinue to use the necessary, higher octane.
Premium Gas Offers Better Performance
This myth is partially true and partially false. The majority of automobiles operate at the same level of performance whether you use standard or premium petrol. You’ll only notice a noticeable difference between the two with particular car models and engine types.
You Need to Use Premium Gas if It’s in Your Car Manual
This myth also rests on circumstantial evidence. Many automakers, like GMC, Ram trucks, and the works, will indicate in the owner’s manual for some of their cars whether they advise or demand the use of premium gasoline. What counts is how these two terms differ from one another.
There are certain advantages to using premium gas when the manual advises against it, but using regular gas won’t hurt your car. It won’t void your warranty in this situation either. Premium gas could potentially improve the performance of these vehicles.
But if the owner’s handbook specifies premium fuel, it signifies the engine does really require higher octane levels to operate properly. Using conventional fuel in these vehicles could potentially harm the engine, and your warranty won’t cover these damages.
Make sure you carefully study your owner’s manual before buying a new or used automobile to make the best decision. Save yourself the money if it’s not necessary.
Premium Gas Lasts Longer
So, is premium fuel more durable? This appears to be a lure of using the ostensibly higher grade fuel for many people. Who among us wouldn’t like to visit the petrol station less frequently?
Regrettably, premium gasoline contains nothing that would extend its shelf life relative to other fuels purchased at the pump. Since the higher octane levels are what set them apart, the only true advantage is a decreased risk of engine knocking, which poses no danger with most contemporary fuel systems.
Premium Gas Cleans Your Engine
This myth is untrue, much like the idea of living longer. The majority of engines are effective in removing residue. You’re in better shape keeping up with routine maintenance checks if you’re worried about the cleanliness of your vehicle’s components.
