Does the Lexus IS300 need premium gas?
The short answer is yes, the Lexus IS300 does require premium gasoline (91 octane or higher). This is because the Lexus IS300 is equipped with a high-performance engine that is designed to run on higher-octane fuel to prevent knocking and ensure optimal performance.
Explaining the Lexus IS300's Fuel Requirement
The Lexus IS300 is powered by a 3.0-liter inline-six engine that produces 215 horsepower and 218 lb-ft of torque. This engine is designed to take advantage of the higher octane rating of premium fuel, which allows for a higher compression ratio and more advanced ignition timing. Using regular gasoline in this engine could lead to knocking, reduced power, and potentially even engine damage over time.
Lexus specifically recommends the use of premium unleaded gasoline with a minimum octane rating of 91 for the IS300. This is a common requirement for many high-performance and luxury vehicles, as the more advanced engine designs often necessitate the use of higher-octane fuel to function properly and deliver the expected level of performance.
Consequences of Using Regular Gasoline
- Reduced engine power and performance
- Increased risk of engine knocking and potential damage
- Lower fuel efficiency and increased fuel consumption
- Possible activation of engine warning lights or other issues
While it may be tempting to save money by using regular gasoline, it is not recommended for the Lexus IS300. The potential consequences of using the wrong fuel type outweigh any short-term cost savings. Lexus engineers have designed the IS300 to perform optimally with premium fuel, and using anything else could lead to long-term issues and decreased vehicle performance.

Fuel economy is not the IS 300's strong suit, with the all-wheel-drive version only EPA-estimated to return 19 miles per gallon in the city, 26 mpg highway and 22 mpg combined. Over the course of a few days, I'm averaging just over 21 mpg.
What happens if I put 87 instead of 91?
If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you'll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.
