Can a Car Using 92 Octane Gasoline Use 95 Octane Gasoline?
1 Answers
A car designed for 92 octane gasoline should not use 95 octane gasoline. Continuously using higher octane fuel than recommended can damage the engine's ignition system, including components like spark plugs, and negatively impact the engine's lifespan. The difference between 92 and 95 octane gasoline lies in the ratio of heptane and isooctane. 92 octane gasoline contains 92% isooctane and 8% heptane, while 95 octane gasoline contains a higher percentage of isooctane and 5% heptane. The higher the isooctane content, the better the anti-knock properties. It is generally advised that car owners adhere to the recommended fuel grade specified inside the fuel tank cap and avoid arbitrarily changing the type of fuel to prevent potential damage to the vehicle. In case of accidentally using the wrong gasoline, do not start the engine and wait for professional assistance.
