Sep 9, 2023 · If you put higher octane fuel in your car, it will run more efficiently and produce less emissions. The higher the octane rating, the more compression the fuel can withstand before detonating. This means that higher octane fuel can be used in higher compression engines without knocking.

An octane rating, or octane number, is a standard measure of a fuel 's ability to withstand compression in an internal combustion engine without causing engine knocking. The higher the octane number, the more compression the fuel can withstand before detonating.

Nov 17, 2022 · In recent years, car manufacturers have been requiring or recommending premium gasoline (a high-octane grade of fuel) for use in more of their vehicle models. The difference in prices between premium and lower octane grades has also increased. Octane ratings are measures of fuel stability.

Aug 4, 2019 · We tested higher octane fuel than manufacturers require on the Honda CR-V, BMW M5, Ford F-150, and Dodge Charger to see if it impacted acceleration or MPG.

Jun 14, 2022 · High octane fuel is advantageous for high-performance engines and isn’t so helpful to regular engines. Like any other fuel, high octane fuel has its advantages and disadvantages, which we will discuss further in the article.

Octane rating is the measure of a fuel's ability to resist "knocking" or "pinging" during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In the U.S., unleaded gasoline typically has octane ratings of 87 (regular), 88–90 (midgrade), and 91–94 (premium).

In the United States and Canada, octane ratings are in AKI, commonly shown as " (R+M)/2". All states require gas pumps to be labeled with the correct octane level and nearly all states do regular testing to make sure gas stations are in compliance.
