How does it differ from regular gasoline? Does your new car require it? We can help you figure that out.

The big difference between regular and premium gasoline is its octane level. You've probably seen those numbers above each pump at the gas station. If the number is above 91, that means it's premium. Higher octane gas can cut down on “engine knock.” Simply put, the engine knocks when it combustion doesn't happen at the correct time. This can reduce the lifespan of your engine if it happens too often.

Higher octane gasoline can prevent engine knock, but does every vehicle need it? The best way to know whether or not your car requires premium gas is by checking your owner's manual. If your new vehicle needs high octane gas, it will let you know.

Sometimes a manual tells you that premium gasoline is simply recommended. That means that filling your car with better gas could improve performance. Some engines only put out their maximum torque and horsepower when you use high octane gasoline. Depending on what kind of car you're driving, it may be worth it to fill up the tank with premium.
