Do Lexus Cars Use Premium Gas?


Premium gasoline costs as much as $0.50 per gallon more than regular. This is a significant amount each time you fill up, and if you’re budget-conscious when filling your vehicle, it’s important to note whether or not your vehicle requires premium gasoline.

Lexus Cars Use Premium Gas.Even if cost is not an issue, it’s important to understand the importance of using premium gasoline in vehicles that require it. Failing to use the right quality of gasoline could lead to severe engine problems and other maintenance issues, which will cost you far more than the price of premium gas in the long run.

Do Lexus cars require premium?

Lexus, a luxury brand, makes many models that require premium gas. However, they are making more and more models that function perfectly fine on regular gas, even if the term “luxury vehicle” has misled you.
It’s true that eight years ago, only one Lexus model that used regular gas, the HS 250H. However, this number has steadily increased to six models for 2019, which include the ES 300H, ES 350, NX 300H, RX 350, and RX 350L. The most recent addition is the 2019 UX urban crossover SUV that also uses regular gas.
If you’re looking for a new or used Lexus for sale, this gives you the option of a luxury sedan or spiffy crossover SUV with cheaper gas requirements.

Understanding octane ratings for Lexus vehicles

While this is gentler on your pocket, octane ratings are very important in high-performance vehicles. Experts describe the importance of octane ratings as follows:

Octane ratings indicate the performance capability of the fuel. Higher octane ratings mean that the fuel can be compressed to a higher ratio without detonating. That’s why high-compression engines need the more expensive premium fuel.”

High-performance engines function at a higher compression ratio, allowing more pressure to build up in the chamber before ignition. If the fuel is correct, it burns more efficiently delivering better fuel economy and performance. Should you use a lower octane rating than specified for your Lexus, the fuel will burn too early. This is called “pre-ignition” which leaves a residue on your engine chamber that, over time, can lead to damage which you will later hear as a pinging noise called engine knock.
The issue can happen with any vehicle with a high-octane rating, but it’s more prevalent in turbocharged engines.

“Since the engine doesn’t make quite as much power with low-octane fuels, this translates into slower acceleration in cars for which premium fuel is recommended,” an Edmunds article says. “The performance loss is noticeable in turbocharged gasoline engines, which have become increasingly popular in recent years.”

All Lexus models are manufactured with a minimum octane rating. The more horsepower and torque your vehicle has, the higher the fuel octane requirement. Lexus, however, has allowed drivers in America to enjoy premium luxury and performance without breaking the bank. That is why there are six models on the market in 2019 that offer everything a Lexus owner expects but, use regular gas for optimum performance.

Learn more

Thankfully, there’s a wealth of information regarding the proper fuel and maintenance for every Lexus vehicle out there. You can read blog posts, watch YouTube videos, ask for recommendations on social media, and visit the manufacturer’s website.
You can also ask your dealer or a trusted mechanic for more information about the proper care and fuel requirements for your vehicle.
All of this is great for learning more about your car, but there’s no better place to determine whether or not your vehicle needs premium fuel than the owner’s manual. Every Lexus owner should become familiar with the manual, especially the section that talks about the correct fuel and oil to use.
Knowledge is power in this case, and the more you know, the longer your Lexus will run without a hitch.
