Why Does My Car Release Smoke After Oil Change: Guide to Know

Introduction to the topic

Do you remember the last time you changed your oil before you saw white smoke coming from under the hood of your car? If so, then it’s time to find out what’s producing all that white smoke. What causes white smoke after an oil change, then, in a car?

Using the incorrect oil, leaving too much oil in the sump, or a leaking valve stem are the most common causes of white smoke following an oil change. A blown head gasket or a broken cylinder can also cause white smoke to come out of the exhaust pipe of the vehicle. If any of those things occur, the oil may not burn properly and produce white smoke.

Every automobile owner has experienced their vehicle releasing a cloud of white smoke. Keep reading to learn more about the white smoke’s origins, why it’s so urgent that you get rid of it, and what you can do about it.

Why is smoke dangerous for a car?

There is useful information contained in your car’s exhaust fumes. Exhaust fumes can have a tint, as they contain a variety of combustion byproducts. It’s normal for the exhaust to be slightly visible or slightly grey after a cold start, for example, but under normal conditions, the exhaust should be nearly invisible.

It’s not typical for smoke to be white, blue, and black. It’s an issue, and it suggests that you’re wasting oil at an alarming rate in your vehicle. In and of itself, this is deeply upsetting. As the oil in your engine burns away, the lubrication that protects its parts from wear and heat generated by operation is diminished. However, that isn’t the only thing you should be concerned about.

It doesn’t take much to send your car to the mechanic unexpectedly; damaged cylinders, improper oil, cracked head gaskets, and much more.

After getting the oil changed, my car started releasing white smoke, why?

A valve stem leak, the use of incorrect oil, or an excess of oil in the sump is the most common causes of white smoke following an oil change. Furthermore, if a cylinder or head gasket is leaking, your car may be releasing white smoke. If that happens, the oil won’t burn as efficiently.

You should get your car checked out right away if you see white smoke coming out of the exhaust pipe after you’ve changed the oil. However, on routine drives, especially when it’s cold outdoors, you may notice that your automobile occasionally releases a little number of white vapors that rapidly disappear.

White smoke is a sign that the gasoline in your car’s engine is condensing back into a liquid after evaporating. You need not fret in such circumstances. However, the following problems may be indicated by the smoke’s persistence and intensity:

1. Using the incorrect oil

Using the wrong oil type or viscosity can cause your car’s engine to produce excessive smoke. What causes this is oil that wasn’t burned completely and made its way into the exhaust system. As a result, white smoke is coming out of your tailpipe.

Fortunately, this problem is easily and cheaply remedied by acquiring the appropriate oil type from any auto supplier.

Expert advice: Before attempting to change the oil in your car, always consult the owner’s manual and do everything precisely as it says to do so. White smoke from your tailpipe could be the result of using the wrong type of oil, which is a common mistake when people fix their cars.

2. There’s too much oil in the catch basin

After an oil change, if you see bluish-white smoke coming out of your tailpipe, there may be too much oil in your car’s engine oil sump. Air pressure prevents used oil from leaking out of the engine and into the sump during an oil change.

If this happens, pull over and have a mechanic remove some of the oil from the sump.

3. Damaged seal on valve stem

White smoke could be produced if oil leaked through the valve stem’s seal and into the combustion chamber. The stem seals of the hollow rubber valves on either side of the valves in your vehicle might be replaced to solve this problem.

These BETOOLL Valve Stem Seal Pliers are an excellent choice if they are required for the job at hand (available on Amazon.com). Their adaptability and compatibility with both aftermarket and OEM (original equipment manufacturer) seals make them a desirable option.

4. An incomplete or broken cylinder

The other cylinders in your engine could be harmed by oil leaking from a damaged one. Possible symptoms include a cloud of white smoke coming from the tailpipe of your vehicle. The presence of such noise is indicative of serious engine problems and should be checked out by a professional mechanic.

If you don’t take care of this issue soon, your automobile may shut off.

5. Head gasket has blown

If coolant or water does not enter the combustion chamber, oil leaked from a blown head gasket will be burned instead of gasoline. Your car’s exhaust will be spewing white smoke as a result.

If you detect this issue with your automobile, don’t wait to get it checked out by a professional; ignoring it for too long might cause serious problems with the cooling system and the engine.

What to do if there is white smoke after the oil change?

There are three possible explanations for why your automobile is smoking after an oil change when it wasn’t smoking before: too much oil in the engine, oil spilled on the engine, or an oil leak. In most cases, the source of the trouble may be identified with relative ease.

Step 1

If you notice the scent of burning oil while you’re driving, pop the hood. Check the engine and exhaust manifold for any oil that may have been spilled during the oil change. Using cloths, remove as much of the spill as possible if you come across one. The rest will usually evaporate while driving. At that point, nobody will light up again.

Step 2

Check the engine for leaks if you think they could be causing the smoking. Please ensure that the dipstick is fully inserted. The oil pan and valve covers should both be inspected for leakage. Put a wrench on any bolts that seem a little sloppy.

Step 3

Check for oil leaks at the oil pan, the drain plug, and the filter by getting under the car. Loosen the filter, loosen the plug, or tighten the bolts on the pan. Try using your bare hands or an oil filter wrench.

Step 4

Put the automobile down on a flat surface. Check the oil level by raising the hood. To learn the specific steps for your model, consult the manual that came with it. Depending on the vehicle, the engine should either be chilly or warm when the oil level is checked.

Step 5

If the dipstick indicates that there is too much oil, you should drain it. Put a second pan under the oil one. Pull the plug and let the oil drip into a container. Put in a new oil plug and check sure it’s securely in place.

Step 6

Verify the oil level with the dipstick and top it off if necessary.

Could I still drive with white smoke coming from the tailpipe?

After learning the cause of the white smoke in the exhaust after an oil change, you may be wondering if you can still drive the automobile. Although white smoke may not look threatening at first glance, it is still best to avoid driving through it. The auto shop is the sole recommended destination for your car. If you keep driving your car without fixing the problem, you’re asking for a lot of trouble.

When an automobile is brought in for maintenance, why does it start smoking?

When car engines overheat, smoke can be seen coming from the exhaust pipe. Overheated oil, transmission fluid, or brake fluid are just a few examples of the many substances that can cause this problem, along with damaged wire casings and residues left on the engine block from the heat. It’s also possible that your engine’s lubrication system is broken or that you just need to add more lube to the system.

Does the automobile smoke if the wrong oil is used?

When synthetic oil is used in the wrong engine, it might cause the gaskets and seals to fail, resulting in a leak. Use of the incorrect oil may be indicated by the accumulation of oil leaks under the vehicle and the appearance of white smoke from the tailpipe.

How about a little white smoke in the car?

If you suspect overheating, pull over immediately. If you choose to disregard it, you may do expensive damage to your car. A problem with the coolant exists if the smoke has a sugary odor.

Bottom line:

White smoke is a common sign of trouble in an internal combustion engine and can have disastrous results if not addressed quickly.

Consult your owner’s manual and only use high-quality engine oil to avoid the bother of fixing this problem. In addition, you need to pay attention to the vehicle’s caution lights. If white smoke appears in the tailpipe, you should have your vehicle serviced immediately.
