Lawn Mower Emitting White Smoke – Here’s Probably Why

Image result for petrol lawn mowerIf you have a petrol mower, then you will have already experienced the multiple benefits that come with using one. Not only are they far more powerful, but they also get the job done in a much shorter amount of time. However, because they run on an engine, there is also more of a chance that you might experience problems with them.

One of the most common problems that people report is the lawn mower emitting white smoke. Below we will go through some of the most common causes behind this and what you can do about it.

Using the Wrong Oil for the Mower

Surprisingly, this is one of the most common causes of a petrol mower emitting white smoke. What happens is the user doesn’t realise that specific grades of oil are suitable for specific types of engine.

By using the wrong grade of oil, you run the risk of your mower malfunctioning. If you have accidentally used the wrong oil, then empty it out and refill it with the correct grade. It may still smoke for a second or two but it should go back to normal fairly quickly.

You Are Tilting your Mower too Much

This is something else that many people don’t realise they are doing that can cause a lot of problems. When you are using a petrol mower, it is important that you don’t tilt your engine by more than 15 degrees.

If you do, then you run the risk of oil leaks which more often than not will cause the engine to start emitting white or blue smoke. If you have realised that this is the problem, then simply make sure that your mower is at the right angle before moving forward and it should stop smoking fairly quickly.

Storing your Mower Incorrectly

To avoid running into problems with the engine of your petrol mower, it is important that you make sure that you store it correctly. A lot of people will attempt to tilt the mower on its side so that it is easier to store.

This is fine if the oil and fuel is empty, but if there is oil or fuel in the tank then you will probably end up with leaks, which will cause the engine to smoke when you next start up your mower. This is why it is very important that you store your mower upright so that the engine is not tilted at all.

You Have Added too Much Oil

Because of this, it is really easy to overfill the oil tank which will result in numerous problems, one of them being white smoke coming from the engine when it is started up.

If you have noticed white smoke then it is definitely a good idea to check the oil level on your mower to see if you have accidentally added too much. If you have then it is simply a matter of emptying it a little and starting up the mower again.

Your Mower Needs Replacing

Sometimes, there are simply no issues that can be fixed and the problem is that your mower simply needs replacing. However, this is very unlikely to be the case if your mower is only a couple of years old and doesn’t get much use. If you have tried all of the points mentioned above and you have also checked with someone in the know, then it might be time to get your mower replaced.

Fortunately, there are plenty of affordable mowers out there so you should be able to replace your model for a fairly reasonable price.
