Motor oil is a significant pollutant of stormwater, which is rainfall that flows over the ground and is not absorbed by the soil or evaporated. Stormwater runoff can pick up and transport various pollutants, including motor oil, and carry them into nearby waterways, causing harm to the environment and human health. Used motor oil from a single oil change can contaminate up to one million gallons of freshwater. To prevent motor oil from becoming a stormwater pollutant, it is essential to address oil leaks in vehicles and properly dispose of used motor oil at designated collection centers. Additionally, individuals can take simple actions, such as using drip pans during vehicle repairs and washing cars on permeable surfaces, to prevent motor oil from entering storm drains and contributing to water pollution.

Motor oil leaks from vehicles are a significant contributor to stormwater pollution
Motor oil leaks from vehicles, along with other automotive fluids, can contaminate stormwater runoff. This is because impervious surfaces can accumulate pollutants, including motor oil, which are then picked up and transported by stormwater into nearby waterways. Used motor oil from a single oil change can pollute up to one million gallons of freshwater. This is especially harmful as motor oil may contain toxic substances like lead, benzene, zinc, or magnesium.
To reduce the impact of motor oil leaks on stormwater pollution, it is important to address oil leaks in vehicles and properly dispose of used motor oil. The U.S. Environmental Protection Agency (EPA) recommends keeping up with automotive maintenance to prevent and repair leaks and disposing of used motor oil at designated drop-offs or recycling locations. Some states, like Florida, provide resources to help identify the nearest center for oil collection.
Additionally, individuals can take preventative measures when repairing their vehicles, such as using a drip pan to catch any oil that may otherwise be washed into storm drains. Simple actions such as these can help reduce the amount of motor oil entering stormwater and ultimately polluting our waterways.

Proper disposal of motor oil is essential to prevent water pollution
Motor oil is a major toxic pollutant. It can pick up hazardous waste, including lead, cadmium, chromium, and arsenic, during its use in engines and transmissions. If not disposed of properly, these contaminants are released into the environment, harming plants, animals, and humans. For instance, if poured down drains or sewers, motor oil can pollute groundwater or surface water.
Used motor oil from a single oil change can contaminate up to one million gallons of freshwater—a year's supply for 50 people. This is because motor oil does not wear out; it just gets dirty. Thus, recycling used motor oil saves a valuable resource and prevents contamination.
Recycling used motor oil is preferable to disposal and can provide great environmental benefits. Recycled motor oil can be re-refined into new oil, processed into fuel oils, and used as raw materials for the petroleum industry. In Wisconsin, recycling oil absorbents and used oil filters recovers more than 1.8 million gallons of oil and more than 4.8 million pounds of steel annually.
To properly dispose of used motor oil, it is important to remember to also drain the oil filters. Puncture a small hole in the oil filter and let the vehicle's oil drain into a drip pan. Then, seal the filter in a plastic bag. Some drip oil pans can be sealed, but if not, transfer the oil into a transportation-safe container and ensure it is tightly sealed. Do not use just any container, as the oil may leak and contaminate the environment. A great option is to use the container that the oil originally came in, or, if that is unavailable, a container made of polyethylene. Be careful not to mix used oil with other liquids, including antifreeze, brake fluids, or water, as it becomes unrecyclable. Make sure your storage container of choice has never been used to hold other liquids.
There are several ways to find a recycling center near you. In Wisconsin, the Wisconsin Recycling Markets Directory and county websites may contain contact information for public works, hazardous waste, or public health departments. You can also use Earth911's iRecycleOil feature to find a drop-off location within your neighborhood.

Toxic substances in motor oil, like lead and benzene, pose a threat to marine life
Motor oil is a significant pollutant, with just one oil change capable of contaminating up to one million gallons of freshwater. When motor oil is washed into storm drains, it can have detrimental effects on marine life.
Motor oil contains various toxic substances, including lead and benzene. These toxins pose a severe threat to the health and well-being of marine creatures. Oil spills and leaks can have devastating and long-lasting impacts on the environment and the animals that inhabit it.
One of the most vulnerable groups is fur-bearing mammals, such as sea otters. Oil destroys the insulating ability of their fur, leaving them exposed to the harsh elements. Birds are also at high risk, as oil removes the water-repellent quality of their feathers, making them susceptible to hypothermia.
Additionally, juvenile sea turtles may become trapped in oil and mistake it for food. Dolphins and whales face the danger of inhaling oil, which can lead to impaired lungs, immune dysfunction, and reproductive issues. Furthermore, many birds and animals ingest oil when attempting to clean themselves, resulting in poisoning.
Even when the impacts are not immediately fatal, oil contamination can cause significant harm. Adult fish may experience reduced growth, enlarged livers, changes in heart and respiration rates, fin erosion, and impaired reproduction. Oil can also make fish and shellfish unsafe for human consumption.
It is crucial to address and prevent motor oil pollution to protect marine life and maintain the health of our oceans and waterways.

Stormwater runoff mobilises pollutants, carrying them into nearby waterways
Stormwater runoff is rain that falls on streets, parking areas, sports fields, gravel lots, rooftops, or other developed land and flows directly into nearby lakes, rivers, and other bodies of water. As urbanization continues to increase, the impacts of stormwater pollution on water quality and ecosystems become more significant.
Stormwater runoff collects a toxic mix of pollutants, including sediment, debris, bacteria, microplastics, heavy metals, and nutrients such as nitrogen and phosphorus from fertilizers and animal waste. These pollutants can have harmful effects on water quality, aquatic life, and human health. For example, nutrients from stormwater runoff can lead to eutrophication, an excess of nutrients that causes excessive algal growth and oxygen depletion in water bodies. The harmful algal blooms that impair Florida's coastal waters have been associated with excess nitrogen from stormwater runoff.
In addition, stormwater runoff can carry eroded dirt that blocks sunlight from reaching underwater grasses, smothering the aquatic homes of oysters and other life. As grasses die, fish and other creatures that rely on them are placed in jeopardy. Stormwater runoff can also increase flood damage in urban and suburban areas with many hard surfaces, as the polluted water has nowhere to go and often floods local streets and basements.
To reduce stormwater pollution, individuals can take several actions. These include properly disposing of waste, using organic fertilizers instead of pesticides and harsh chemicals, maintaining vehicles to prevent leaks, and washing cars at commercial car washes or on permeable surfaces with biodegradable soap. Communities can also work to prevent stormwater runoff as development takes place, and residents can reduce their use of single-use plastics and other waste that can end up in waterways.

Preventing motor oil pollution involves regular vehicle maintenance and responsible disposal
Motor oil is a significant pollutant, with just one oil change's worth of used motor oil capable of polluting up to one million gallons of freshwater. To prevent motor oil pollution, it is essential to practice regular vehicle maintenance and to dispose of motor oil responsibly.
Regular vehicle maintenance is key to preventing motor oil leaks, which can result in oil spills that contaminate stormwater. When repairing or maintaining your vehicle, use a drip pan to catch any leaking oil, and be sure to recycle the oil at a certified collection center. Keep your vehicle in good condition by examining it for leaks and ensuring that it is up to date with oil changes.
In addition to proper maintenance, responsible disposal of motor oil is crucial. Used motor oil should never be dumped into the ground, as it can seep into the water supply. Instead, allow the oil to cool, then transfer it to a sealed container for transport to a recycling center. Many auto care facilities offer oil recycling services, ensuring that the oil is disposed of in an environmentally friendly manner.
To further reduce the impact of motor oil pollution, consider taking your car to a commercial car wash, where the water is treated before being drained, reducing potential pollutants. If washing your car at home, use biodegradable soap on a permeable surface to allow the runoff to be absorbed into the ground.
By combining regular vehicle maintenance with responsible disposal and conscious washing practices, we can significantly reduce motor oil pollution and protect our freshwater sources and the environment. These simple actions can make a substantial difference in safeguarding our waterways and the ecosystems they support.
