What happens if you don’t fill a 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.
Do all Lexus vehicles need premium fuel?
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.

Which Lexus vehicles can use regular fuel?
Most Lexus vehicles can operate just fine on ordinary unleaded gasoline and do not require premium fuel. These models consist of:
- 87 IS Octane (Regular Unleaded)
- Octane ES87 (Regular Unleaded)
- Octane CT87 (Regular Unleaded)
- Octane NX87 (Regular Unleaded)
- 87 LX Octane (Regular Unleaded)
- Octane LS87 (Regular Unleaded)

You won’t harm the engine or see a performance drop if you use standard unleaded fuel in these vehicles.
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.
Which Lexus vehicles accept normal fuel?
- RX, NX Hybrid, and UX (regular or hybrid) all require 87 octane (regular fuel)
- Use 91 octane for an NX, RX hybrid, GX, and LX, it is advised (premium fuel).

Does the Lexus RX 350 from 2012 need premium fuel?
The Lexus RX was first introduced in 1999 and most recently revised and reengineered for 2010. There have been few changes subsequently. The 2012 RX 350 has been adjusted, most importantly, to run on standard unleaded (87 octane) fuel. It is advised to use premium (91 octane) gas for the 2012 RX 450h.
(The 2013 Lexus RX models will have new interior materials and updated appearance. In summer 2012, the 2013 RX is anticipated to go on sale. The only significant difference between the 2013 and 2012 versions will be how they look.)
In comparison to comparable SUVs, the 2012 Lexus RX 350 and RX 450h are simple to drive and have a softer ride. Additionally, they use less gasoline than many of their rivals.
The 3.5-liter V6 engine in the RX 350, combined with a 6-speed automated multi-mode transmission, outperforms the Acura MDX, Mercedes ML 350, and BMW X5 xDrive3.5i’s fuel economy figures. The RX 450h hybrid delivers even greater gas mileage and is rated as a Tier 2-Bin 3 emissions vehicle in all other states, as well as a Super Ultra Low Emissions Vehicle (SULEV II) in California.
You can choose between front-wheel drive and all-wheel drive for the 2012 RX 350 and RX 450h. The RX 350 features a central differential-free lightweight all-wheel-drive system that is controlled by an electronic connection on the rear differential. The RX 450h does not require a mechanical connection between the axles because the back wheels are driven by an electric motor. Entire Review

What happens if 87 octane fuel is used in a 93 octane vehicle?
ATLANTA
Half of the east coast is experiencing a fuel scarcity as a result of the Colonial Pipeline cyberattack. Due to this, many gas stations are experiencing shortages, higher gas prices, and gallon restrictions.
Many people have inquired as to the distinction between standard grade and premium fuel as some gas stations only carry standard grade fuel due to fuel shortages.
In order to determine the risks associated with not using the proper fuel in your car, our VERIFY team consulted with the experts.
WHAT WE KNOW
A standard grade 87 or 89 is advised for the majority of vehicles on the road. It’s perfectly fine to fill a normal vehicle with premium gas between 90 and 93. According to auto experts, using premium fuel won’t harm a basic automobile in any way.
Is premium fuel actually worthwhile?
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
What occurs if 89 fuel is used in an 87 vehicle?
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.
