How Long Can a Car Engine Sit Without Starting It?

The answer to this question depends on a variety of factors, including the age of the car, the type of engine, the climate, and how well the car is maintained.

Factors that Affect How Long a Car Engine Can Sit Without Starting It

Age of the car: Older cars are more likely to have problems with their engines sitting for long periods of time. This is because the seals and gaskets in older engines are more likely to deteriorate, which can lead to leaks and other problems.
Type of engine: Diesel engines are more likely to tolerate sitting for long periods of time than gasoline engines. This is because diesel engines do not require spark plugs to ignite the fuel, so they are less likely to develop problems with ignition.
Climate: Cars that are stored in hot climates are more likely to have problems with their engines sitting for long periods of time than cars that are stored in cold climates. This is because the heat can cause the oil in the engine to break down, which can lead to wear and tear on the engine.
Maintenance: Cars that are well-maintained are more likely to be able to sit for long periods of time without starting them. This is because regular maintenance helps to keep the engine in good condition and prevents problems from developing.

How to Prepare a Car for Sitting for a Long Period of Time

If you are going to store your car for a long period of time, there are a few things you can do to help prepare it:

Change the oil and filter: This will help to keep the engine lubricated and prevent sludge from forming.
Fill up the gas tank: This will help to prevent condensation from forming in the tank and causing problems with the fuel system.
Add fuel stabilizer: This will help to keep the fuel from going bad and causing problems with the engine.
Disconnect the battery: This will help to prevent the battery from draining and causing problems with starting the car.
Cover the car: This will help to protect the car from the elements and prevent dust and dirt from accumulating on it.

How to Start a Car that Has Been Sitting for a Long Period of Time

If you are going to start a car that has been sitting for a long period of time, there are a few things you should do:

Check the battery: The battery may have drained while the car was sitting, so you will need to check it and make sure it is charged.
Check the fluids: The oil, coolant, and brake fluid may have leaked or evaporated while the car was sitting, so you will need to check them and add more if necessary.
Turn the engine over: Before you try to start the car, turn the engine over a few times by hand to help circulate the oil.
Start the car: Once you have checked the battery and fluids, you can try to start the car. It may take a few tries to get the car started, so be patient.
