What is the difference between Regular and Premium Gas?

Both Regular gas and premium gas are fuels for car engines. The two are similar in terms of their usefulness and there are also differences between the two. Regular gas is the most common fuel for cars because it contains no lead compounds which makes it less hazardous to human health. It is gotten from crude oil. It has an octane rating of 87, this refers to its ability to resist improper combustion in the engine.

Premium gas is also a product of crude oil. It performs relatively functions similar to premium gas. But it has a higher price than regular gas. The octane rating is about 90 and more, this is where it differs from regular gas. The octane rating of 90 in premium gasoline means that it is able to withstand knocking just a little more than regular gas. Because of its high octane ratings it causes less pollution, it will leave your engine very clean and that's why most people go for it.
