What happens when you put regular gas instead of super?
Using regular gas in an engine that requires premium could void your warranty. ... If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.”
Does Super gas 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.
Can I put premium gas in my car if I use regular gas?
Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.

Why do some cars require 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.
Does premium gas last longer?
Sadly, there's nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn't much of a threat on most modern fuel systems.
