Causes Of White Smoke From Your Lawn Mower

There are a few potential causes of white smoke from your lawn mower.

1. Oil Level In The Engine Is Too Low

One potential cause of white smoke coming from your lawn mower is that the oil level in the engine is too low. This can cause the engine to overheat, which will lead to a build-up of pressure inside the engine. The pressure can then force oil into the combustion chamber, where it will be burned along with the fuel. This will produce thick, white smoke.

2. Water In The Gas Tank

Water in the gas tank is one potential cause of white smoke from your lawn mower. This can happen if the gas tank is left out in the rain or if you accidentally fill it up with water instead of gasoline. Water in the gas tank will cause the engine to run erratically and produce white smoke.

3. Air Filter Is Dirty

When you notice white smoke coming from your lawn mower, it may be a sign that the air filter is dirty and needs to be replaced. The air filter helps to keep the engine clean and running smoothly by trapping dirt and debris before they can enter the engine.

If you don’t replace the air filter when it’s clogged, the engine will eventually become damaged. The white smoke is a result of the engine burning oil, which can cause long-term damage to your lawn mower. To avoid this, be sure to check the air filter regularly and replace it as needed.

4. Fuel Mixture Too Rich

A potential cause of white smoke is a problem with the fuel mixture. If there is too much oil in the mixture, it can cause the same issue as mentioned above. The oil will burn along with the fuel and produce a thick, white smoke

5. Faul Spark Plug

Spark plug fouled with oil Another potential cause is that the spark plug may be fouled with oil. Check this by removing the spark plug and checking for oil on it.

6. Engine Fouled With Grass

Fouled engine Another potential cause of white smoke is that the engine may be fouled with grass or other debris. If this is the case, then you should get your lawn mower serviced by a professional lawn mower repair shop.

How Do You Fix The Problem Of White Smoke From Lawnmowers?

Fix The Problem Of White Smoke From Lawnmowers

Lawn Mower White Smoke And Sputtering

When it comes to lawn care, one of the most important pieces of equipment is the lawn mower. A lawn mower can make or break a perfectly manicured lawn. One of the most common problems with lawn mowers is when they begin to sputter and emit white smoke. This can be caused by a number of different things, but the most common cause is a dirty air filter.

A dirty air filter can restrict air flow to the engine, which can cause the engine to run lean. When an engine runs lean, it means that there is not enough fuel being burned in the combustion chamber. This can lead to pre-ignition, which is when the fuel ignites before it should. Pre-ignition can cause serious damage to the engine and will eventually lead to the engine seizing up completely.


White smoke from lawn mowers is dangerous because it contains high levels of pollutants that can cause health problems and environmental pollution. To avoid these health risks, it is important to take steps to reduce the amount of pollution produced by lawn mowers. One way to do this is to switch to an electric lawn mower, which does not produce any emissions. You can choose to use a manual lawn mower, which also emits far less pollution than a gas-powered model.

You should take your lawn mower to a mechanic as soon as possible to get it fixed. Otherwise, you could end up having to replace the entire engine, which is very expensive.
