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.

Does 89 octane fuel work in a Lexus?
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.

Regular fuel works well with the majority of Lexus vehicles. The UX, UX Hybrid, NX Hybrid, and RX Lexus SUVs may all be operated on conventional fuel without causing engine damage. These vehicles need ordinary gas with a minimum suggested octane rating of 87.
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.
The company advises that high performance vehicles should have an octane level of at least 91.

Does the Lexus GX 460 come from Japan?
The Lexus GX is a full-size luxury SUV that is sold in North American and Eurasian markets by Lexus, a high-end branch of Toyota. The Toyota Land Cruiser Prado, from which the GX derives its off-road prowess, serves as its base. In 2002, Lexus debuted the first generation, also known as the GX 470, which later became the third SUV to join the Lexus lineup. With low-range gearing, a full-time four-wheel drive system is standard. The larger LX 470’s 4.7-liter V8 engine was also utilised in the GX 470. The second-generation model was then released by the company in 2009 under the name GX 460 to reflect the upgrade to a 4.6-liter V8 engine. Later, in 2012, Lexus released a GX 400 with a smaller displacement and a 4.0-liter V6 engine for the Chinese market.
The GX is positioned between the RXcrossover and the LX SUV in the Lexus lineup (the Lexus-badged Land Cruiser). The Land Cruiser Prado, the Toyota 4Runner, and the GX have all been produced in the Tahara facility in Japan.
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.
Which Lexus models are fuel-efficient?
- RX, NX Hybrid, and UX (regular or hybrid) all require 87 octane (regular fuel)

Are normal and premium gas blendable?
Can I combine unleaded and premium gas? 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.
Do I actually require premium fuel?
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.
Does premium fuel make your engine cleaner?
There used to be a significant difference in engine performance between cars using standard gas and premium gas. In order to overcome problems brought on by increased compression ratios, premium gas was advised for vehicles with higher performance engines. There were additives in premium gas that let these engines run as they were intended to and endure severe driving. The detergents and additives in today’s premium fuels assist clean fuel injectors and eliminate carbon buildup from inside engines, encouraging drivers of vehicles with regular-fuel engines to occasionally use premium gas to maintain their engines.
Depending on where you live, premium petrol might cost anywhere from 20 to 50 cents more per litre than regular gas today. At the gas pump, this may mount up quickly. While occasionally filling up with premium fuel may seem like a smart idea, it might not provide the benefits you’re after. Let’s talk about whether or not such expensive upkeep is cost-effective.
The main distinction between normal and premium gas is the octane rating. Regular gas has an octane rating of 87, whereas premium gas has a rating of 91 or higher. High octane fuel aids in preventing premature fuel ignition, which causes engine banging and can harm your car. In comparison to conventional fuel, high octane fuel may be heated and compressed more before self-igniting. Because of this, high-octane fuel is only used in high-performance automobiles.
What vehicles genuinely require 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.
