Spilled Gasoline on Grass? Here Is What You Should Do!

Gas can on grass

You can’t get rid of bad luck easily; having dead grass on your lawn’s visible sections is painful. Spilled gasoline seems to be the most common cause of such an unfortunate incident, although there could be other reasons for this as well. That being said, what can be done if you spilled gasoline on your grass?

First, you need to dig out the old soil and replace it with fresh soil. You should not go any deeper than 3 to 4 inches when digging the dead patch. Once you’ve replaced the soil, you can plant new seeds into the fresh soil. Water it regularly to obtain the desired results within days.

I thought of using water to wash away spilled gasoline when the same thing happened to me a few years ago. The thing I did, however, did not help me much. You may also have questions regarding its effects on surrounding patches of grass. This blog post aims to discuss these issues in detail to help you deal appropriately with the problem.


What Happens When You Spill Gas on Grass?

A large portion of the gas evaporates into the environment. However, the soil absorbs some of the gasoline. As a result, that soil loses its agricultural and cultivation value. After some time, the grass that sucks the spilled gasoline turns into dead patches that begrime the beauty of the entire lawn.

The problem with this issue revolves around the speed of reaction on the grass. As soon as gasoline gets in contact with the grass, it starts killing it without any delay. The grass immediately turns into dead patches, and even the underlying soil loses its value and gets contaminated.

Luckily, there are many possibilities to fix this issue, depending on the amount of gas spilled and whether or not it was combined with oil. Some people get away with a few gallons of water on the contaminated spot, while the rest of the gardeners seek no other refuge than to replace the damaged soil.

Below are some of the most effective hacks you can use to fix the problem.


A brown or yellowish lawn is definitely not a sight to see, some may even consider it dead. The good thing is, there are a lot of things that you can do to revive your lawn and make the grass green again. If you want to have your lush and green lawn back, here are our tips to bring dead grass back to life


What to Do If You Spilled Gas on Your Lawn?

As already mentioned, the magnitude of spillage determines the most appropriate technique. In the case of a massive gasoline spillage, you need to replace the contaminated soil with a fresher one. On the other hand, you will need a different solution if a few drops of gasoline are spilled from the lawn mower’s gasoline tank.


Will Spilled Gasoline Kill Grass?

As previously mentioned, spilled gasoline is likely to kill grass if you do not employ the appropriate technique. You may consider two options based on the magnitude of gas spillage. You can either wash the gasoline off with water or replace the contaminated soil with fresh soil.


Does Water Wash Away Gasoline?

You can use a few gallons of water to treat the spillage when the quantity of gas spilled is minimal. In general, 4 to 5 drops of gasoline cannot cause any damage to the grass, but if the spillage amounts to 3 to 5 tablespoons, you must clean it up with water.

Try to use an excessive amount of pressure to get rid of the contamination in the first go. The quantity of water also matters a lot in this regard. You cannot rely on 2 to 3 quarts of water for the treatment of contamination. Instead, the quantity required in this situation is in gallons.

All in all, if the spillage is minimal, treating it with water is a good idea.

One thing to keep in mind is that if you do not use this technique appropriately, the problem may worsen. Indeed, if you fail to flush spilled gasoline away, it can spread quickly into more areas due to water pressure. As a result, you will have greater chances of getting more semi-dead patches of grass.

That is why professionals prefer digging, which minimizes gasoline spread by replacing the contaminated soil.


Replacement of Contaminated Soil

The digging technique is more effective to permanently fix the problem. When the quantity of spilled gasoline is in gallons, you will need this solution for sure.

In the beginning, mark the contaminated area that requires treatment. Try to include areas covered with dead and semi-dead patches of grass. Remove the soil by digging 3 to 4 inches of the soil. Dispose of it properly in a safe location. The target place must then be refilled with fresh soil after cleaning out the contaminated soil.

Depending on your environment and requirements, you may use black topsoil or any other suitable soil for this purpose. Once you have successfully replaced the soil, you need to plant new seeds with compost mix. Keep watering the spot regularly to obtain the desired effects within days.

One thing you need to take care of in this regard is selecting the seed. Never use a type of seed that is different from the one already used on the lawn. In this way, all of your grass will have a uniform color.

Is There a Quick Hack?

Luckily, I have an intelligent hack for people who do not like digging or excessively watering their lawns. If you’re one of those, all you have to do is buy a new plant pot. Fill it with beautiful plants to cover the dead patches. In this way, you can get rid of these dead patches within minutes.

The rest will be taken care of by Mother Nature by the following summer. Naturally, new patches of grass will grow over the dead ones. After which you can remove the pot from your lawn.

This hack, however, is only meant for lazy people who don’t want to work through the dirt all day. The tilling technique remains the best choice if you do not want to settle for anything less than the best.
