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.

Why is premium fuel required for Lexus?
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?
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.
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.
