Here are the key things that happen when there is no gas in a car:
1. Engine Misfiring: As the car starts to run low on gas, the fuel pump may struggle to deliver an adequate supply of fuel to the engine. This can cause the engine to start misfiring. You may notice a rough running engine, engine knocking, and reduced engine performance.
2. Engine Shut Off: When there's no gas left, the engine can no longer run, and it will eventually shut off. This can happen suddenly or gradually, depending on how quickly the car is using the remaining gas.
3. Fuel Pump Damage: Running a car on empty might cause damage to the fuel pump. As the fuel pump operates without being properly cooled by the surrounding gas, it can overheat and fail. This damage may require expensive replacements or repairs.
4. Loss of Steering and Braking: Some vehicles use power steering and power braking systems that rely on the engine running. Without gas, the engine-driven vacuum pump powering these systems cannot operate, leading to reduced or inconsistent power assistance for the steering and brakes.
5. Catalytic Converter Damage: In some modern cars, running out of gas can damage the catalytic converter, a vital component of the exhaust system. This happens when the unburned fuel enters the catalytic converter, damaging its catalytic coating.
6. Stranded Vehicle: If you run out of gas in an inconvenient or unsafe location, you may be stranded until you can get assistance, such as having the vehicle towed to a gas station or having someone bring gas to you.
It's important to avoid running out of gas whenever possible as it can cause problems for the engine, fuel system, and your overall safety on the road. Always keep an eye on your fuel gauge and refuel before the fuel level gets too low. If you're ever worried about running out of gas, consider buying a gas can and keeping it in your vehicle for emergencies.
