Why is My Car Leaking Oil?

At Underriner Motors, we often remind our Billings customers that regularly changing your oil is the most crucial thing you can do to care for your new Buick. The purpose of motor oil is to cut down on friction inside your engine. Over time, as you drive around Bozeman, oil becomes dirty and loses its thickness. 

If you wait too long between oil changes, you could get an oil leak under your car. Other factors could also make a car leak oil. If you’re wondering what causes oil leaks in your vehicle, read on or contact Underriner Motors.

Common Signs of a Car Leaking Oil

One of the most common signs of a car leaking oil is seeing a puddle of greasy-looking brownish liquid underneath your car after it has been parked for a while. That’s a sure sign that you have an oil leak under your vehicle. Another thing to look out for is if your engine is covered in oil. 

That’s why it’s a good idea to open your hood every once in a while to look around and check your vehicle’s fluids. Lastly, when oil is leaking, if it comes in contact with hot engine surfaces, it will burn, and you’ll be able to smell it or see smoke.

What Causes Oil Leaks in Cars?

Many Laurel drivers ask our service team what causes oil leaks in cars. Often it is due to degraded engine gaskets or oil seals. Sometimes these auto components will deteriorate over time, but more likely, it’s because of dirty oil due to not having your oil changed frequently enough.

Damaged Oil Gaskets or Pans

Your Buick’s oil pans and gaskets can be damaged by road debris because they are located at the bottom of the engine, underneath the car. Rough roads can cause a hole which will cause an oil pan leak. The oil pan’s gasket can also suffer a lot of wear and tear, or it can be damaged, which leads to an oil gasket leak.

Incorrect Installations

Sometimes if one of the gaskets that keep oil inside is incorrectly installed, you’ll get an oil leak under your car, especially if the oil pan gasket or valve cover gasket is over-tightened. The same thing can happen when tightness is not evenly distributed. Another reason for an oil leak can be the improper installation of the oil filter, as the engine oil flows continuously through it, and if it’s loose, you can get an oil leak there.
