Blue smoke coming from your car’s exhaust is generally an indication that oil is seeping into the engine and being burned along with the fuel.¬†

This usually occurs when the engine is low on oil. There is also the possibility that there is an external oil leak, and the oil is dripping onto the exhaust system.

If your car’s engine is smoking after you put oil in it, there are a few possible causes. The most common reason is an oil spill on the engine. 

When too much oil is added to the engine, it can spill onto hot surfaces and begin to smoke. Another potential cause is an oil leak. If there is an oil leak somewhere in the engine, adding more oil can cause it to overflow and smoke.

Finally, if you simply put too much oil in the engine, it can cause smoking as well. In this case, the best course of action is to drain the excess oil and wait for the rest to evaporate. 

Whatever the cause of your smoking engine, a quick diagnosis will help you get back on the road in no time.

Why is my car smoking but not overheating?

The most frequent cause of smoldering smoking is that some sort of fluid has fallen on the engine. This could be oil, fuel, transmission fluid, coolant, or even condensation.

When the fluid is burned off by the engine, it can cause smoke. If you’re not sure what type of fluid is causing the smoke, it’s best to take your car to a mechanic and have it checked out. 

They’ll be able to identify the source of the problem and recommend the best course of action. In some cases, simply changing the oil or replenishing fluids may be enough to fix the issue. 

However, if there is more serious damage, such as a leak in the engine, it will need to be repaired before your car will run properly again.

Can wrong oil cause car smoking after oil change?

Oil leaks can be a serious problem for car owners. If left unchecked, they can cause extensive damage to the engine and other parts of the vehicle. One of the most common causes of oil leaks is using synthetic oil in the wrong type of engine. 

Synthetic oil is designed for use in engines that require a high level of lubrication, such as those found in race cars. However, when synthetic oil is used in an engine that doesn’t require such a high level of lubrication, it can cause gaskets and seals to leak. 

As a result, car owners should be sure to check their owner’s manual before selecting an oil type. Another sign that a car may have an oil leak is white smoke coming from the exhaust. 

This is caused by oil burning off in the engine, and it can be a sign that the engine is running too hot. 

If you notice either of these signs, it’s important to have your car checked by a professional as soon as possible. Left unchecked, oil leaks can lead to serious engine damage.

Can a dirty oil filter cause smoke?

If your oil filter becomes clogged, it will cause the exhaust gases to be redirected back into the engine. 

This can result in a number of problems, the most immediate of which is the production of dark exhaust smoke. 

The smoke will be sooty and very noticeable, especially when the engine has been running for some time. 

In addition to being unsightly, this smoke can also lead to a build-up of carbon deposits on engine parts, causing them to wear out prematurely. 

If you suspect that your oil filter is clogged, it is important to have it replaced as soon as possible. Doing so will help to keep your engine running smoothly and prevent costly repairs down the road.

Increased emission is also a clogged catalytic converter symptom so make sure you check it as well.

Can low coolant cause smoke?

Low coolant can sometimes be the cause of a blown head gasket. 

If this happens, you may notice smoke coming from the engine or tailpipe, a loss of power, engine knocking sounds, or decreased efficiency.

Replacing the head gasket is a major repair that should be done by a professional. 

How long should I wait to drive after adding oil?

Once you have your oil, it is important to ensure that your car is parked on level ground before proceeding. This will allow for a more accurate reading of the dipstick. 

The engine should also be cool to the touch to avoid any potential burns. Allow the oil to drain fully back into the sump by waiting at least 20 minutes before checking the level again. 

Add oil in small amounts until the desired level is reached. Remember to dispose of any used oil in a responsible manner.


When it comes to diagnosing and repairing your car, smoke is rarely a good sign. If you have determined that your car smoking after oil change, it is best to consult with a professional. 

They will be able to accurately diagnose the problem and provide you with a solution.
