A car leaking a small amount of oil when parked is quite normal. It is also not dangerous, but it can cause a mess on the ground. Anything more than a small oil leak visible on the ground may cause you to wonder if your car has a problem and if there is anything you should do to fix the leak. Let’s try to put your mind at ease by looking at this issue a little deeper.
A common reason for an oil leak is worn-out seals. These seals are what keep the oil in and make sure that it doesn’t escape. When they start to wear down, that’s when you might notice an oil leak and this will be most noticeable when you park your car or leave it idle for long periods of time.
There are plenty of homemade fixes available for this issue like using silicone sealant to fill in any gaps around your engine block, but these fixes can be very messy and take a lot of time to complete. There are also car-specific products available at your local auto store that will fix this problem.
However, it is always best to identify why the leak is occurring and replace the faulty part so that the leak stops. This can be as simple as replacing a gasket on your engine so that the oil can no longer escape from the seal. in some cases, though it may not be so simple and you will need to have it looked at by a qualified mechanic.

Why Does My Car Leak Oil When Parked?
This is a question that has plagued so many drivers over the years.
Oil leaks can be very frustrating, because it may not be easy to trace where the oil is coming from especially when the car has been parked for a long period of time. To make it even harder to find the source of the problem, most engines are quite dirty and may have oil covering different parts of the engine.
This is another reason why keeping your car well-maintained and clean is not only good practice, it is very helpful should an oil leak occur.
Oil leaks that drip from a parked car is usually caused by the following:
- A faulty seal on the oil pan, gasket or filter
- A worn valve stem seal or O-ring that is leaking engine oil into the crankcase or camshaft bearing housing
- Worn out engine seals and gaskets causing small amounts of oil to seep past them and drip onto the ground
- Oil pan bolts that are loose or missing, causing an oil leak at the bottom of the vehicle
Some detective work and a good eye may be necessary to locate the source of your oil leak, but this should be quite easy for any mechanic or anyone with experience in fixing cars. If it is just a matter of replacing a worn-out gasket or seal, then it shouldn’t cost much to repair, and depending on which gasket has failed it may be quite a simple job to remove the old gasket and fit another one.
Possible Causes of a Car Leaking Oil When Parked
A car can leak oil because of many possible reasons. The most common way for this to happen is when the oil filter isn’t tightened enough or if there is a crack in the engine or oil pan. There are other possible causes of leaking oil, including faulty hoses, bolts, and seals.
But why do cars leak oil when parked, anyhow?
Many cars leak oil when they are parked because the engine is off and has cooled down. Because it has cooled down the metal shrinks slightly increasing any gap between the metal that is sealed with a gasket. When the engine runs, not only is there oil pressure, there is also the expansion of metal parts which help to push the seals tighter together so less oil escapes.
Oil leaks while parked are not always caused by valve seals and gaskets, in some cases, other engine components can also cause leaks.
If you see oil leaking from your car when it’s parked, there are three things that may be causing it:
– The dipstick tube seal has worn out
– The valve cover gasket has sprung a leak
– A cracked head or blown head gasket
The above are just three possible causes but there are others that may need checking.
How to Solve the Problem of a Car Leaking Oil When Parked
Parking garages are often filled with vehicles leaking oil when parked. This can lead to slippery conditions and result in accidents. The oil can also lead to a fire if it is not properly contained.
The problem of a car leaking oil when parked can be solved by using a car cover or parking the vehicle on an absorbent surface.
How to Prevent Oil Leakage on Your Car
Oil leakage is a serious problem since it can cause some major damage to your engine. Here are a few ways that you can prevent oil leaks on your car.
1) Check the engine for any fluid leaks at least once every week. If you find any, then get them fixed as soon as possible.
2) Change the oil filter of your car at regular intervals. Make sure not to overfill as this can leak out of the engine. You should also ensure that you use the correct oil for your car. It needs a certain viscosity, use the wrong type and your engine performance will suffer and oil leaks can happen more often.
3) Regularly check the battery and air filter of your car to make sure that they are not clogged or dirty.
4) Keep track on the levels of the different fluids in your car and replace them when required.
5) It’s highly recommended that you get a routine inspection done on your car at regular intervals to check that everything is in good condition. If a mechanic does this he may spot something that can prevent an oil leak from happening, or fix it before it gets worse.

Oil Leak Detection in your car
Oil leaks can be a big problem for your car if not detected in time. Oil leak detection is the process of identifying and locating the source of an oil leak. Actually, identifying the exact source of an oil leak in your car can be surprisingly difficult.
When driving any oil that leaks will be blown by air and will eventually go in many directions and cover the engine so detecting an oil leak can sometimes be like looking for a needle in a haystack! There are, however, some handy tips on this page at PopularMechanics.com.
One thing that they advise is the use of dye you place in the oil to trace any oil leak. The color in this dye is fluorescent when you shine UV light on it. This really can help you to see where any oil leak is coming from.
If an automobile’s engine has an oil leak, there are usually three ways to detect it: by looking for signs of leakage, checking for smoke or exhaust fumes, or measuring the level of fluid in the car’s crankcase.
The first step is to figure out if the leak is happening while the car is running, or only when it’s not moving. If there’s a leak that happens just while the car isn’t moving, then it could be that your valve cover gasket needs replacement. If you can’t see any leaks under your hood, but see signs of leaking oil on the ground around the engine area, then it’s likely that an oil pan gasket has failed or been damaged by another part of your engine or drive train.
Parking your car outside for a few days will lead to oil leaking from the engine. Oils are used in the engine for lubrication. Oil being leaked from the engine is one of the most common problems in cars. It may be due to a specific leak, or it may be due to poor-quality oil being used in your car.
Oil leaks can lead to several issues, including mechanical failure of various parts in your car, so it is essential that you take care of any potential cause of an oil leak as soon as you notice it to avoid this escalating into a much more serious problem.
The leaked oil is also very harmful to the environment and hence you should take care of it immediately if you find any leakage in your car.
