Does buying premium gas make a difference?
So is Higher Octane Fuel More Efficient? In a word, no. On its own paying for premium gasoline does not make your car run better or get greater gas mileage. Giving your car the fuel it requires to run smoothly and efficiently, without damage to the engine, does make a difference in your fuel mileage.

Does higher octane gas really make a difference?
Raising the octane rating (also known as the anti-knock index) doesn't change the energy content of a gallon of gasoline. A higher octane rating indicates greater resistance to knock, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.

What is a mistimed explosion?
A mistimed explosion, also said as “pre-ignition” or engine knock is known by these names because it simply sounds like knock or ping. A high gasoline resists the engine knock.

What makes premium gas different?
But that’s in all gasoline, so what makes premium gas different? At its root, it’s an increase in octane. Octane is one of those hydrocarbons in gasoline, and it increases the resistance of gasoline to detonate prematurely in your engine. The higher the octane content in your fuel, the more resistant it is to predetonation that causes spark knock or pinging.
Why does predetonation cause carbon deposits?
Over time, the predetonation causes abnormal wear in the cylinders, excessive carbon deposits because the fuel isn’t burned cleanly, and can cause damage that requires expensive repairs if left for a long time . In high-compression engines, premium gas waits to ignite until the spark plug fires.

What is the difference between premium gas and regular gas?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates.

What is knock sensor?
The sensor detects the pinging or knocking sound and then relays the information to the rest of the system. The system then delays the spark timing to keep the unwanted flame from happening. This setup usually allows you to use lower octane fuel if you choose to in your higher-performance engine.
