Lexus GX, NX, RX Hybrid, and LX are some other SUVs that need premium fuel. The minimum gas octane level required by Lexus is 91, which is premium gas.
All Lexus coupes, which are high-performance automobiles, need premium gas with a high octane rating. These cars’ engines operate at a high compression ratio to produce more power. Regular gas will cause knocking, which will harm the engine.

What happens if 87 gasoline is placed in a 91 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.
What happens if I don’t fill up my Lexus with premium fuel?
Your Lexus’s performance and power may suffer if you don’t fill it up with premium gas. This can eventually result in engine damage. Lower-octane fuel won’t directly harm the engine, but it can make the engine make knocking and pinging noises as the air/fuel mixture ignites too quickly in the cylinders.
Fortunately, not every Lexus car needs premium fuel. The more entry-level Lexus cars typically don’t need premium fuel.
To be absolutely certain, you can always examine the owner’s manual or your nearby Lexus dealer.
Lexus employs premium?
Do you have to pay more for a Lexus then? The answer is dependent upon the particular model you are operating. While some cars, like the 2022 Lexus ES, can run on standard 87-octane fuel, other cars, like the 2022 Lexus GX, need premium 91-octane fuel to perform at their best on the St.

If I don’t use premium gas, what happens?
Other factors to think about include the possibility of component damage, voiding your warranty, and engine knocking or pinging that sounds like a big woodpecker is under your hood if you don’t use high-octane fuel in your premium vehicle. Ouch.
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.
Does the 93 octane rating matter?
Why spend a lot of money on something you don’t require? Premium petrol costs around 50 cents more per gallon than regular gas and doesn’t affect vehicles that can’t use it in any way. The Federal Trade Commission warns consumers that, “In most circumstances, using gasoline with a higher octane rating than your owner’s manual suggests delivers absolutely no benefit. It won’t improve the efficiency, performance, speed, or mileage of your vehicle.
In order to clean your engine and improve performance, the detergent additives in your gasoline are significantly more significant than the octane rating. Every shop offers a unique mixture of additives that are applied to all grades. For instance, Chevron’s Techron is available in both their normal and premium gas.
Some people hold themselves to a higher standard when it comes to additives. The Top Tier Gasoline standard, which requires a higher-percentage of detergent additive than the EPA minimum criteria, was developed with the assistance of BMW, General Motors, Honda, Toyota, Volkswagen, and Audi. They contend that lesser detergent additive concentrations may cause greater deposits to form on engine parts like the intake valves and fuel injectors. As a result, emissions may rise and engine performance may be affected. j
Why does Lexus require expensive fuel?
When refueling your car, we advise using at least the minimum octane rating. A lower octane level than what is recommended for your model year car may cause engine knocking, which could eventually result in permanent engine damage. Additionally, using the incorrect fuel for your Lexus will violate its warranty, which will ultimately cost you more than the money you initially saved at the pump.
Should You Use a Higher Octane Than Recommended?
It won’t harm your automobile to use higher-octane fuel than is advised, but it also won’t help. High compression ratios or turbochargers are common features of premium gas engines. Regular gas engines lack the appropriate parts to benefit from the increased performance and fuel economy brought on by premium gasoline. Why spend an extra fifty cents a gallon on premium fuel when you don’t need it?
Can I fill up my Lexus IS300 with normal gas?
In order to get the best performance out of your IS300, Lexus does advise using premium unleaded fuel with a minimum octane level of 91 or above. To get the most performance and power out of the engine of your car, this is typically advised. Always fill up your car with higher octane fuel; it’s a smart suggestion.
What vehicles need premium fuel?
If a luxury car has a high performance or turbocharged engine, premium gas may be necessary. More opulent trim levels for a car may provide engine options that require premium gas, even if you’re not buying a luxury vehicle. The make and type of your car ultimately determines whether it requires premium gas or not. Find out more about luxury and sports car insurance.
What happens if you combine gasses 87 and 93?
When it comes to this kind of thing, it’s always better to be cautious than sorry. The answer is that not much happens when you combine 87 and 93 gas.
Regular, midgrade, and premium gas grades are terms used to describe the octane content of the fuel. Those numbers 87 and 93 are measuring the same thing. Gas with an octane rating of 91 or higher is classified as premium gas, whereas gas with an octane rating of 89 or 90 is classified as midgrade gas.
Higher octane gas is generally better for your engine and will produce marginally better performance. On the other hand, you obtain their average when you combine two distinct octane levels.
Then you have a full tank of 90-octane gas if you have exactly half a tank of 87-octane gas and half a tank of 93-octane gas.
It will never be an issue to add higher octane gas to an engine made to use lower octane gas. However, if you use regular petrol in an engine that requires premium, you’ll experience performance troubles.
