Does premium gas last longer than regular gas?

Why do some cars need premium gas?
Simply put, high-octane gasoline can be compressed and heated to a greater degree without self-igniting. That’s why high-performance engines use premium fuel. Since the engine doesn’t make quite as much power with low-octane fuels, this translates into slower acceleration in cars for which premium fuel is recommended.
What happens if you accidentally put regular gas instead of premium?
Using regular gas in an engine that requires premium could void your warranty. That is most likely to happen if using regular causes severe engine knock or pinging (premature ignition of the fuel, also known as detonation) that damages the pistons or other engine parts.

Why is premium gas so expensive?
Q: Why does premium gas cost so much more than regular? A: According to a U.S. Department of Energy website on fuel economy, the fuel components that boost octane are generally more expensive to produce. Most gasoline vehicles are designed to run on 87 octane, but others are designed to use higher octane fuel.
Does 93 gas burn slower?
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.
