How to Remove Thick Old Oil from Car Engine

Safety First

Before you start working on your car, it is important to take some safety precautions. Make sure to park your car on a level surface and engage the parking brake. Allow the engine to cool down completely to avoid burns. Wear gloves and safety glasses to protect yourself from hot oil and chemicals.

Materials You Will Need

• New engine oil
• New oil filter
• Oil drain pan
• Funnel
• Wrench or socket set
• Oil filter wrench
• Rags or paper towels

Step-by-Step Instructions

1. Locate the Oil Drain Plug

The oil drain plug is usually located on the bottom of the oil pan. It is typically a 17mm or 19mm bolt. Use a wrench or socket to loosen the plug, but do not remove it completely yet.

2. Place the Oil Drain Pan

Position the oil drain pan under the oil drain plug. Make sure the pan is large enough to catch all of the old oil.

3. Remove the Oil Drain Plug

Carefully remove the oil drain plug. Be careful not to drop the bolt into the oil pan. Allow the oil to drain into the pan.

4. Replace the Oil Drain Plug

Once the oil has drained out, replace the oil drain plug. Tighten the plug until it is snug, but do not overtighten it.

5. Locate the Oil Filter

The oil filter is usually located near the top of the engine. It is a cylindrical-shaped component with a black cap. Use an oil filter wrench to loosen the filter.

6. Remove the Old Oil Filter

Carefully remove the old oil filter. Be careful not to spill any oil. Dispose of the old filter properly.

7. Apply Oil to the New Oil Filter Gasket

Apply a thin layer of new engine oil to the gasket of the new oil filter. This will help to create a seal and prevent leaks.

8. Install the New Oil Filter

Screw the new oil filter onto the engine by hand. Once it is hand-tight, use the oil filter wrench to tighten it another 3/4 turn.

9. Add New Engine Oil

Use a funnel to add new engine oil to the engine. Add the amount of oil specified in your vehicle’s owner’s manual. Check the oil level on the dipstick to ensure that it is at the correct level.

10. Start the Engine and Check for Leaks

Start the engine and let it idle for a few minutes. Check for any leaks around the oil drain plug and oil filter. If you see any leaks, tighten the plug or filter until the leak stops.

Tips

• If the old oil is very thick, you may need to use a solvent to help dissolve it. You can purchase a commercial oil solvent or use kerosene or diesel fuel.
• If you are having trouble removing the oil drain plug or oil filter, you may need to use a penetrating oil. Apply the penetrating oil to the bolt or filter and allow it to sit for a few minutes before trying to remove it.
• Dispose of the old oil and filter properly. You can take them to a local recycling center or auto parts store.

Conclusion

Removing thick old oil from your car engine is a relatively simple task that can be done in about an hour. By following these instructions, you can save money and keep your car running smoothly.
