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?
What kind of fuel can a Lexus run on?
You need to use unleaded fuel with an octane level of 87 or higher in order to comply with Lexus regulations. As the premium octane grade for gasoline is 91, the RX does not require it. It’s not necessary to use premium gas in your Lexus RX, but it can result in greater performance.
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)
- 87 LX Octane (Regular Unleaded)
- Octane NX87 (Regular Unleaded)
- Octane LS87 (Regular Unleaded)
- 87 GX Octane (Regular Unleaded)
- Octane CT87 (Regular Unleaded)
- Octane ES87 (Regular Unleaded)
You won’t harm the engine or see a performance drop if you use standard unleaded fuel in these vehicles.

Do luxuriant cars require premium fuel?
To operate with greater fuel efficiency and to maximize their speed and performance, luxury cars need premium petrol. Even while you may use normal gas in a luxury automobile, doing so frequently will increase engine wear and could violate your warranty.
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.
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.

- 2011 Lexus CT200h: The new Lexus hybrid offers everything you’d want in a posh car without the extra maintenance costs associated with using premium fuel. The vehicle’s incredible performance is made possible by a combination of electric power and a 1.8-liter gasoline engine that runs on ordinary fuel.
- The 3.6-liter V-6 engine or the 2.4-liter four-cylinder engine power the 2014 Buick LaCrosse. Both engine choices, when propelled by ordinary gas, can deliver sufficient performance.
- Volvo S60/S60 Cross Country: Although Volvo suggested premium gas to maximize the engine’s performance, the S60 Volvo vehicles that are powered by the 2.0-liter turbo-four engine may still be driven on regular gas.
- 2013 Infiniti M37: Although premium gasoline is advised for the luxury automobile, ordinary petrol offers the same performance.
- The 2012 Cadillac CTS sedan is another luxury Cadillac vehicle that only needs ordinary gas to operate properly. It has a 3.0-liter engine, and even though it doesn’t have the best fuel economy, using premium gas has no effect on how well it runs.
- 2011 Hyundai Equus: Hyundai isn’t typically associated with luxury cars, but the Equus is the company’s attempt to enter this market by providing a quality interior and standard luxury features. Even with ordinary gas, the 4.6-liter V-8 engine delivers a luxurious level of performance.

What happens if you don’t fill up a fancy vehicle with premium fuel?
The majority of luxury cars have engine-knock sensors, which prevent the engine from knocking even if you use the incorrect gasoline. Because avoiding engine knock prevents engine damage, normal gas rather than premium will probably work just fine in your engine.
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.
