I don't know about you, but when I go to the filling station, there are at least three different options of fuels I can put in my vehicle. Some fuels that don't work well in my vehicle come with spouts that don't fit, so I can't even put them in if I wanted to.

There are regulations that state diesel spouts are this size, and regular gasoline spouts are that size. This keeps us from mixing things up and putting the wrong fuel in our vehicles. Besides that, it's really hard to put anything but gasoline in most vehicles due to the design of how the tank is filled.

You'd never put anything but gasoline in your vehicle. If you want higher performance out of your vehicle, you put higher performance gasoline in it. Without the proper fuel, a vehicle won't run well or at all.

Have you ever considered that a grocery store is a filling station for you? Have you ever considered that what you put in your body is fuel? Have you ever considered that you're being sold subpar fuel and paying heavily for it? Have you ever noticed problems with your vehicle's operation?
