How Long Can a Car Sit Before Engine Goes Bad

A lot of people think that when it comes to cars, the engine only lasts for a certain amount of time. In reality, this isn’t always the case. A car’s engine can last for anywhere from 100,000 miles to upwards of 300,000 miles or more! So if your car is nearing the end of its life, don’t panic – there are still plenty of things you can do to extend its lifespan.

What Causes a Car Engine to Go Bad?

A car engine can go bad for a variety of reasons, but the most common cause is fuel injection issues. If the fuel injectors are not functioning properly, the car’s engine will not be able to ignite the proper amount of fuel, which will eventually cause it to fail. Other causes of car engine failure include worn or broken parts, clogged filters, and incorrect timing.

How to Check for Engine Problems

If you’re like most drivers, you probably don’t give your car’s engine much thought. But a faulty engine can quickly become a major problem, and not just because it’ll slow you down. Here are four simple ways to check for engine problems:

1. Listen for strange noises. If you hear unusual sounds from your car’s engine, there’s a good chance it’s in trouble. For example, if it’s making a high-pitched noise, or if the engine starts making weird knocking noises, your car may have a problem.

2. Check the oil level. If your car has an oil gauge, make sure it’s at the top of the “full” range. If it’s low or empty, that means your engine may not be getting the lubrication it needs to run smoothly.

3. Check the coolant level. Just as important as oil is coolant; if it gets too hot, the metal parts in your engine can start to burn. Make sure the coolant level is full and not leaking.

4. Check the brakes and tires.

How to Fix a Car Engine That Has gone Bad

If you have a car that is not running right, the first thing you should do is try to determine why it’s not running. If you can’t find the problem, then it might be time to take your car to a mechanic. However, if you can determine the reason your car isn’t running, then you can try to fix the issue yourself. Here are some tips on how to fix a car engine that has gone bad:

1. Check the Battery

If your car won’t start, one of the first things you should do is check the battery. Is there power going into the battery? If not, then your alternator might be broken or your battery might be defective. You can test your battery by turning on your car and seeing if it starts. If it does, then your battery is probably good. If it doesn’t, then you’ll need to replace your battery.

2. Check for Fuel Issues

Another thing to check is for fuel issues. Make sure there is enough fuel in the tank and that there aren’t any clogs in the system. If there are clogs, you’ll need to clean them out using a plunger or a vacuum cleaner. 

What to Do if You Find a Dead Car Battery

If you find a dead car battery, here are some things to do:
1. Remove the dead battery as soon as possible. A dead battery can cause dangerous conditions if left in a car.
2. If the car has an emergency key system, use the key to start the car and then remove the battery. This will minimize the risk of starting the car with a dead battery.
3. If the car doesn’t have an emergency key system, wait until someone is available to help you remove the battery. The removing of a dead battery can be dangerous if done incorrectly.
4. Call a tow truck to take the car to a nearby service station or mechanic for replacement.


This is a difficult question to answer because there are so many factors that can affect it. Some examples of things that could cause your car’s engine to go bad include: neglect, faulty parts, age, and viruses. However, the most common reason for a car’s engine to fail is due to wear and tear. The normal lifespan of a car engine is around 150,000 miles, but this number can vary depending on how you drive and maintain your vehicle. If you are concerned about your car’s engine going bad sooner than expected, it might be a good idea to have it checked by a mechanic.
