Effects of Using 87 Instead of 91 Octane Gas in a Lexus
If you accidentally put 87 octane gas in a Lexus that requires 91 octane, the effects may vary based on the specific circumstances and the duration of use. Here’s what you can expect:
Immediate Impact:
– The immediate impact of using 87 octane gas in a car that requires 91 octane is not likely to cause significant harm to the engine.

– Continuously using 87 octane instead of 91 octane in a Lexus can potentially lead to serious damage to the engine over an extended period.
Manufacturer’s Recommendation:
– It’s important to adhere to the manufacturer’s recommendation for the octane rating of the fuel. Using a lower octane fuel than recommended may lead to engine knocking and potential damage, which could void the vehicle warranty.
In summary, while using 87 octane instead of 91 octane in a Lexus may not cause immediate harm, it’s crucial to address the situation promptly and avoid prolonged use of the lower octane fuel to prevent potential engine damage.
