Should Lexus ES Use 92 or 95 Octane Gasoline?

[VonColeman]

Lexus ES manufacturer recommends using fuel with an octane rating of 92 or above, so 92 octane fuel is sufficient. How to choose gasoline octane rating: In fact, higher octane rating doesn't necessarily mean stronger vehicle power or lower fuel consumption. The manufacturer's recommended fuel octane rating can be found on the inner side of the fuel tank cap and on the nameplate below the vehicle's B-pillar (under the front passenger seat). As long as you follow the manufacturer's recommended fuel octane rating, there will be no issues. Gasoline octane rating: It represents the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane rating, the stronger the anti-knock performance. Standard gasoline consists of isooctane and n-heptane. Higher octane rating isn't always better; you should choose the appropriate gasoline octane rating based on the engine's compression ratio.
