5 Facts About Automobile Fuel Pumps

Did you know that the first fuel pumps were operated by hand? That’s right! People had to put their hand in a metal box and turn a crank to pump the gas. While today’s modern pumps are easy to use, there are plenty of people who still don’t know about them. So, let’s take a look at some of these interesting fuel pump facts to keep in mind while driving around in an Empire Rent A Car rental.

5 Facts About Automobile Fuel Pumps

1. Stations Only Stock Two Grades of Gas

Gas stations typically only stock two grades of gasoline-regular and premium. This is because not all vehicles can run on premium gasoline. So, while you might have three or four options at the pump, only two sources are underground. The pump simply mixes the correct ratio of each, depending on your selection.

2. Fuel Pumps Know When the Tank is Full

Thanks to a small tube near the nozzle tip, fuel pumps are typically smart devices and can tell when the tank is full. As the pump puts fuel in your tank, air seeps out of that tube. But once the fuel reaches the nozzle tip, a vacuum is created, triggering the switch in the nozzle handle to shut off the pump.

3. E Stands for Ethanol

Ethanol is a plant-based fuel, and almost all of today’s diesel and gasoline mixtures contain some level of ethanol. The name or label at the pump stands for how much ethanol is present in the mix. For example, E10 means 10 percent ethanol and 90 percent gasoline. Remember that not all cars can run off ethanol, so always check the label near the fuel tank cap.

4. Premium Fuel is Worth the Price

While you might think that premium fuel is just a way to get more money out of you, the truth is that it can actually be worth the price. Premium fuel typically has a higher octane rating than regular gasoline, which means the engine runs more smoothly and efficiently. Additionally, other additives can help protect the engine, keeping the vehicle running for years.

5. Octane is Not an Additive

Most people think that octane is an additive that you put in your fuel tank, but it’s actually a measure of the fuel itself. The higher the octane rating, the more compression the fuel can withstand before detonating. This is important because it prevents “knocking” or “pinging” noise in the engine, which can damage the vehicle over time.
