Motor oil from your lawn tools can sometimes drip onto your lawn. A few drops here and there won't affect your plants, but if you have a large leak or if you spill a lot of motor oil on your lawn, it can harm your soil and kill your plants. You'll need to remove the oil as soon as possible by shoveling it away. You may tear up your lawn a bit in the process, but you'll save your soil from long-term damage.
Things You'll Need
Press a shovel into the ground to remove the top 4 inches of dirt along with any sand and spilled oil. You will have to remove the grass in this process.
Place the dirt, oil and sand into a wheelbarrow and discard the contents.
Reseed or resod the lawn as necessary to blend the area with the rest of the yard.
