Keeping your used car in top condition is essential for its longevity and performance. One of the most important maintenance tasks is regularly checking and changing the oil. Engine oil lubricates the moving parts of the engine, reduces friction, and helps dissipate heat. Over time, oil breaks down and becomes less effective, making it crucial to replace it at recommended intervals. In this guide, we will walk you through the steps to check and change your car’s oil efficiently.
If you’re considering upgrading to a newer vehicle, don’t forget to explore the latest used car inventory. Ensuring your car runs smoothly can also improve its trade-in value when you’re ready to make a switch. Learn more about the ideal time to trade in your old car.
Why Checking and Changing Your Oil Is Important
Oil plays a crucial role in your car’s engine. Without it, the metal components would grind against each other, causing excessive wear and potential engine failure. Here are some benefits of regular oil maintenance:
- Enhances Engine Performance: Fresh oil keeps the engine running smoothly and efficiently.
- Prevents Overheating: Clean oil absorbs and disperses heat more effectively.
- Reduces Engine Wear: Lubrication minimizes friction and prevents excessive wear.
- Improves Fuel Efficiency: A well-lubricated engine uses fuel more efficiently.
- Extends Engine Life: Regular oil changes prevent sludge buildup and corrosion.

If your oil needs changing, follow these simple steps:
Step 1: Gather Your Tools and Materials
You will need:
- New engine oil (check your owner’s manual for specifications)
- A new oil filter
- A wrench set
- An oil catch pan
- A funnel
- A jack and jack stands (if necessary)
- Gloves and safety goggles
Step 2: Drain the Old Oil
- Run the engine for a few minutes to warm up the oil, making it easier to drain.
- Use a jack to lift the car if necessary and secure it on jack stands.
- Place the oil catch pan beneath the oil drain plug.
- Use a wrench to loosen and remove the drain plug, allowing the old oil to drain completely.
Step 3: Replace the Oil Filter
- Locate the oil filter and unscrew it using an oil filter wrench.
- Apply a small amount of new oil to the rubber gasket of the new filter.
- Install the new filter and tighten it by hand.
Step 4: Add New Oil
- Reinstall the drain plug securely.
- Open the oil filler cap and use a funnel to pour in the new oil.
- Check the oil level using the dipstick to ensure it’s at the correct level.
Step 5: Run the Engine and Check for Leaks
Start the engine and let it run for a few minutes. Check underneath for any leaks. Turn off the engine and recheck the oil level, adding more if necessary.
How Often Should You Change Your Oil?
The frequency of oil changes depends on your car’s make, model, and driving conditions. Generally:
- Conventional oil: Every 3,000 to 5,000 miles
- Synthetic oil: Every 7,500 to 10,000 miles
- Severe driving conditions (e.g., frequent short trips, extreme temperatures): More frequent changes may be necessary

- Dashboard Oil Light: If the oil warning light appears, check your oil immediately.
- Dark or Dirty Oil: Fresh oil is amber-colored, while dirty oil appears dark and sludgy.
- Engine Noise or Knocking: Lack of lubrication can cause unusual engine noises.
- Exhaust Smoke: Excessive smoke from the exhaust may indicate burning oil.
- Poor Performance or Low Fuel Efficiency: Dirty oil can lead to sluggish engine response.
