What is the Difference Between Regular and Premium Gas?

Gasoline is made from refined crude oil, but the type of gas can vary among vehicles, with some exceptions like diesel, biodiesel, and ethanol alternatives. Octane rating is a measurement that differentiates the types of gas available at the pumps in Weston. The higher the octane rating, the higher the performance yield of the fuel, with high-performance engines usually requiring a premium, high-octane fuel with an octane rating of around 91-94. Lower octane fuel is usually rated around 87.

What is Premium Gas & Does Mercedes Require Premium Gas?

Premium gas has a higher octane level, reducing the chances of engine knocking caused by delayed combustion when vaporized gasoline is compressed by pistons. This is crucial in high-performance engines, producing smooth and quick acceleration for drivers in Weston. If you want to prolong your Mercedes-Benz engine’s lifespan and enjoy better fuel economy, premium gas is the way to go.

Using lower-octane gasoline with a high-performance vehicle can cause short-term and long-term issues. The fuel may ignite too soon in the engine, causing the sound of engine knocking or pinging as you accelerate. If this problem arises, schedule a service appointment with our team at Mercedes-Benz of Fairfield for a solution.
