The Lexus brand is known for luxury, style, and performance. Vehicles built to give their best deserve your best in return. Depending on your model, you must ensure that Lexus cars get the proper grade of gasoline, even if that means spending slightly more on a higher-octane formulation.

The Difference Between Regular and Premium Gas

Premium gas has a higher octane rating, typically above 91. It’s specifically formulated for higher-compression engines commonly found in performance and luxury vehicles like Lexus models. Using regular gas in high-compression engines leads to knocking that, besides sounding terrible, causes heavier engine wear.

Lexus Models That Can Take Regular Gas

A few Lexus models suggest but do not require premium gas. All Lexus ES trims (the Lexus ES 250, Lexus ES 350, and hybrid versions) can run on regular, as can the Lexus UX Hybrid and the NX 250 since neither have turbocharged engines.

What Happens if I Use the Wrong Gas in My Lexus Car?

Using regular gas one time in your vehicle won’t do it any favors, but it also won’t cause the engine to fail. Repeated use is different since it will degrade performance, fuel economy, and engine life.

The main reason for premium gas is to eliminate the knocking you will get from regular gas, especially in a turbocharged engine. There is another consequence, however: using regular gas in a vehicle that requires premium could void your warranty, so read – and heed – your owner’s manual.
