What happens if I accidentally put regular gas in my Lexus?
Lexus requires that the minimum gas octane rating be 91, which is premium gas. All Lexus coupes, which are high-performance cars, require high octane premium gas. The engines of these cars run with a high compression ratio to generate more power. Using regular gas will lead to knocking, which results in engine damages.
You should use premium gasoline on the Lexus RX 350 to maintain its performance and longevity. This is a higher-octane fuel, which means it is more resistant to pre-ignition than regular gasoline. It also typically costs more.
What octane gas does a Lexus ISF take?
Most Lexus models require you use at least 91 octane (premium) gasoline, while there are a few that can use 87 octane regular unleaded.
When your car needs a higher-octane gasoline, it means that the fuel can better resist the unwanted combustions that happen when the air and fuel mix in your engine. If you have a higher-performance vehicle, like a Lexus NX, premium gasoline is typically recommended since the engine is specifically designed for it.
Can I put 87 in my Lexus IS250?
Lexus IS250 Owners’ Manual wrote: Premium unleaded gasoline with an octane rating of 91 (Research Octane Number 96) or higher required for optimum engine performance. If 91 octane cannot be obtained, you may use unleaded gasoline with an octane rating as low as 87 (Research Octane Number 91).
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.
