How Can I Find My Oil Leak?

Oil LeakFinding an oil leak can be a difficult task.  Especially in today’s vehicles due to the overwhelming amount of plastic shielding and covers used, oil leaks can disguise themselves and be near impossible to detect.  If you’ve grown up looking under the hood, then you’ve probably noticed the increasing amount of plastic covers and shields being used in the engine bays of new vehicles today.  So what is all the plastic about?  The plastic covers that are new being installed on top of engines are today’s replacements for wire coverings.  Older vehicles would individually cover or hide wires in looms and conduits.  Automobile manufactures have found it’s easier and less expensive to simply put a large cover over the entire motor rather than dressing up or covering individual components.

Besides the plastic covers on top of your engine, many vehicles also have a significant amount of plastic coverings under the car as well.  The main purpose of the under vehicle coverings is to direct air flow.  The plastic shields help direct air flow through your vehicle’s radiator and out of the back of the engine compartment helping to keep your vehicle cool as well as direct air around your vehicle while driving to help increase aerodynamics and reduce drag.  If you have to remove any of this plastic shielding during any maintenance on your vehicle it’s important to replace it once the maintenance is complete to ensure proper cooling and aerodynamics of your vehicle.

Even though the plastic shields under your vehicle are there for a reason, they still can make it extremely difficult to determine the location of an oil leak.  The starting point for discovering the location of any oil leak is by looking at the location of any drips you see on the ground after parking your vehicle.  Plastic shielding under your vehicle may catch these drips and make it difficult to get an accurate idea of the leak location or leak severity.

If you’ve discovered an oil leak, the best way to find its location is to remove all the plastic shielding and climb under your vehicle with a flash light and mechanics mirror.  Before you roll under your vehicle, make sure it’s not running, in park with the emergency brake on, and the wheels securely chocked for your safety.  Once you’re under your engine, start looking for fresh oil.  If oil has been slowly leaking for a long time it will have attracted a significant amount of road dirt and grime and will look more like black mud or dirt stuck to your motor.  A fresh oil leak can be identified by wet, shiny oil spots dripping down your engine block or oil pan.  As oil drips it will drip down your motor but also towards the back of your car as the air blows over your motor while you drive.

oil leakAs you search for fresh oil, start your search at the bottom rear on the engine bay and move your way forward and up.  The highest and most forward point you discover oil will be at the source of the leak.  Don’t be fooled by oil leaking from a higher source down onto another component.  If you have an extremely old vehicle, or dirty engine with multiple oil leaks it may be necessary to clean your engine to remove old oil and leaks to help identify the actual source.  You can clean your engine using engine degreaser available at your local auto parts store or at a carwash using the under carriage cleaning option.  After you’ve cleaned up your motor, go for a quick drive and then start your search for your leak.

If all this sounds like a lot of work and a long time on your back in the driveway, you’re right.  Unless you get lucky and have an oil leak in an easy to identify location such as a valve cover gasket or oil pan gasket, you may be in for a lot of crawling around with dirt and dust falling in your eyes.

The great news is BlueDevil has developed an easier way to find your oil leak.  If you add BlueDevil oil Stop Leak to your engine oil, it will seek out your oil leak from the inside of your engine, and when it finds the leak it will create a permanent seal.  BlueDevil Oil Stop Leak is a liquid leak sealer that will not harm or clog your engine in anyway.  BlueDevil Oil Stop Leak will mix with your engine oil to create a powerful seal conditioner that will revitalize and restore the seals and gaskets in your engine returning them to their original size sealing your oil leak.  BlueDevil Oil Stop Leak can save you the time and discomfort of rolling around in your driveway and help return your car to its normal, reliable operation.

      The BlueDevil Oil Stop Leak is intended for leaks that are dripping or seeping out. If you are losing oil at a rapid rate, you would not be able to keep the product in the system long enough for it to seal.

      Thank you!


  1. I have a Nissan cube 2010, I took my car to have the socks checked, and when they raised it it had a very slow oil leak, it hasn’t hit the ground yet, but it is on the oil pan. I check the motor oil and it’s OK, the color of the motor oil is the same as the oil on the bottom of the oil pan. Can I pour blue devil into it so it will fix it or do I need to know positively if that is the leak

    1. Mercedes-

      Based on your description, it would be safe to use the BlueDevil Oil Stop Leak. Typically, you should start to see results after about 100-200 miles of driving.

      One bottle of the BlueDevil Oil Stop Leak will treat 4-6 quarts of oil. You may check your owner’s manual to find your oil capacity and then you can add the appropriate amount of the product.

      Thank you!

  2. I’m considering buying a car that the owner advised me had a small oil leak. He says he’s pretty sure it was caused by his brother losing the original oil pan plug and replacing it with an incorrect size. When I showed up to test drive the car, the owner informed me he had just used your product, but that it wasn’t supposed to be driven for a particular period of time after your product was added and it had only been about half the time he indicated. It was test driven a few blocks at this time. My first question is will having driven it before the specified time cause it to be ineffective.
    My second question is I’m considering taking it for an oil change after I purchase it (if I go forward with the purchase). How soon is it safe to change the oil. I

      In order to get the benefit of using the product, the vehicle would need to be driven about 100-200 miles before you would start to notice improvement. There is no specified time that the vehicle must rest when the product is added. It does not have to be a continuous drive. You are fine to go 5, 10 mile intervals, it would just be around the 100 mile mark before you would start to notice any kind of results. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!
