If you suspect an oil leak under your car, it’s essential to address it promptly to prevent potential damage to your vehicle. Checking for oil leaks involves a few straightforward steps that you can perform at home before consulting a professional mechanic.

How to Check for Oil Leaks Under Your Car

To check for oil leaks under your car, start by parking your vehicle on a flat surface and placing a clean sheet of cardboard under the engine area. Leave it overnight, then inspect the cardboard for any oil spots. Additionally, visually inspect the engine and surrounding components for oil residue or drips.

Step-by-Step Guide to Identify Oil Leaks

1. Prepare Your Vehicle

   • Park your car on a flat, dry surface.
   • Ensure the engine is off and cool to prevent burns.

2. Use a Cardboard Test

   • Place a large piece of cardboard or newspaper under the engine area.
   • Leave it overnight to check for any oil drips.

3. Inspect the Engine Bay

   • Open the hood and use a flashlight to look for oil residue.
   • Pay attention to the oil pan, valve cover gasket, and oil filter area.

4. Check Oil Levels

   • Use the dipstick to check if the oil level is lower than usual, which might indicate a leak.

5. Look for Oil Spots

   • Examine the ground where your car is usually parked for any oil spots.
