The dangers of oil spills


Engine oil spills are very serious. Not only can they damage your vehicle, but they can even ruin the environment around it. If you notice an oil leak, you need to get it taken care of right away.

Some of the dangers of an engine oil spill include:

  • Oil is easily flammable making oil spills a dangerous hazard. Starting your car can cause this oil to ignite, risking your safety and the safety of your passengers.
  • Oil leaks are bad for your engine along with your car’s radiator and HVAC system.
  • Oil spills are bad for the environment. Oil can leak into a storm drain where it can reach and harm our lakes, rivers and oceans.
  • Your engine leaking oil is even bad for your health 

What causes oil leaks?

Most oil leaks are caused by 4 common problems:

  • A degraded engine gasket can lead to an oil leak
  • When your oil pan gasket leaks, it can eventually cause the engine to start leaking too
  • Excess oil can cause it to overflow and leak out
  • A failing filler cap that is loose or broken can lead to an engine leaking

How to find an Oil Leak


The first indicator that your oil may be leaking is if your engine oil is low. Use the dipstick to measure your engine’s oil levels to help you spot any leaks.

If your engine’s oil is low, you’ll have to crawl under your vehicle to determine the location of the leak.

You will also need to check if your vehicle emits blue smoke while the engine is running. This usually means that oil is leaking into the engine itself. While the engine is on, check for a burning smell too.

If you notice any of these indicators, then it is likely that your engine is leaking oil.

How to fix an oil leak

There are two main ways to fix an oil leak:

  • By using an additive: this is the easiest way to fix the leak. You’ll need to use a stop leak additive to soften and condition your car’s rubber seals and stop the leak. It may take a few hundred miles before the leak is fully fixed.
  • By using tools: first, you’ll need to jack up your car so that you can safely access the oil pan. Check for loose bolts and tighten them. After tightening all the bolts on the oil pan, be sure to check the timing belt cover and the valve covers too. Check your owners manual for more information.
