The Lexus IS 300 can use different types of fuel depending on the generation of the vehicle. In the first generation (2001-2005), the Lexus IS 300 used a 3.0L engine and required premium 91 octane gasoline. In the second generation (2016-present), the Lexus IS 300 is equipped with a 2.0L engine and can use regular unleaded gasoline with an octane rating as low as 87 . It’s important to note that using a lower octane fuel may result in reduced performance and fuel mileage.

Can I put 87 gas in my Lexus IS300?
The IS really isn’t running high enough compression to where putting 87 octane will be detrimental to the engine. I personally just alternate between 91 octane when gas prices are not as high and 87 octane when gas prices go crazy.
So, do you have to put premium in a Lexus? The answer depends on the specific model you’re driving. Some vehicles like the 2022 Lexus ES can utilize regular 87-octane fuel whereas other models like the 2022 Lexus GX require premium 91-octane fuel to provide you with optimal performance on the St. Petersburg roads.
First, using too low of a grade of gas can lead to engine knocking, which can cause long-term damage to your engine. And second, using regular gas when you should use premium could void your warranty, meaning you would have to pay for any costly repairs out of your own pocket.
What kind of gas does the 2018 Lexus IS 300 take?
So all grades (87, 89 and 91) octane are E10. You vehicle requires a minimum of 91 octane. So 91 or higher octane is what to use. Using a lower octane under hard acceleration could do serious damage to your vehicle.
Can you put 89 gas in a Lexus?
The 2023 Lexus ES 350 needs a minimum octane rating of 87, although you can use premium gasoline if you want. When you go to the gas station, you’ll generally see octane ratings of 87, 89, and 91. You might see 93 as super-premium.
Most Lexus models require you use at least 91 octane (premium) gasoline, while there are a few that can use 87 octane regular unleaded.
Can you put 87 in a IS300?
If you make a habit of using 87 octane instead of 91+, you run the risk of wearing your pistons and rod bearings quickly. The IS has a higher than normal compression engine (normal is 10:1 but the IS300 runs 10.5:1) so that’s why they ask for the extra octane.
First, using too low of a grade of gas can lead to engine knocking, which can cause long-term damage to your engine. And second, using regular gas when you should use premium could void your warranty, meaning you would have to pay for any costly repairs out of your own pocket.
While your Lexus RX uses regular (unleaded) gas with an octane rating of 87, your Lexus SUV can take premium fuel with an octane rating of 91. The use of premium gas may enhance your vehicle’s performance, but the choice to use standard or premium gas is entirely up to you.
