Types of Gas for a Car

"Hi! This is Don Wolstenholme on behalf of Expert Village. We are going to show you how to pump gas. In this segment we are going to choose what octane and fuel to use. As you can see, we have three different octanes of gasoline to choose from and each of them perform a different function. This is regular unleaded. It works in most cars today. Super unleaded is for vehicles that have may a high performance engine or a higher octane requirement. Premium is for high performance engines as well as towing vehicles especially in warmer weather. The difference between all these three gasolines is basically they all have the same additives but they just have an extra ingredient in the super unleaded and premium unleaded that allows the slower burn of the gasoline especially under low odor hot conditions so it doesn't cause a ping sensation in your engine. That happens in the summertime usually if you have too low of octane and a heavy load on the engine you get a loud rattle sound such as the vehicle that pulled up next to us."
