Changing your car’s oil is one of the most important maintenance tasks to keep your engine running smoothly. Regular oil changes enhance engine performance, improve fuel efficiency, and extend the life of your vehicle. While you can get your oil changed at a mechanic’s workshop, doing it yourself can save money and give you a better understanding of your car.
This guide will walk you through a step-by-step process to change your car’s oil at home in Pakistan. Whether you drive a conventional petrol or diesel car or a modern hybrid, this article will provide you with all the essential details.
Benefits of Changing Your Own Oil
Changing your car’s oil yourself has several benefits:
- Cost Savings – Professional oil changes can be expensive. Doing it yourself can save labor costs.
- Better Vehicle Maintenance – You gain firsthand knowledge of your car’s condition.
- Convenience – No need to wait in long queues at workshops.
- Use High-Quality Oil – You can choose the best oil and filter rather than relying on what the mechanic provides.
Tools and Materials Needed
Before you start, gather all the necessary tools and materials to make the process smooth.
Essential Tools:
- Oil drain pan – To collect old oil
- Socket wrench – To remove the drain plug
- Oil filter wrench – To remove and tighten the oil filter
- Funnel – For pouring new oil
- Jack and jack stands – To lift the car safely
- Gloves and rags – To keep your hands clean
- Empty container – For old oil storage and disposal
Materials:

Choosing the Right Engine Oil for Pakistan’s Climate
Pakistan has extreme weather conditions, ranging from hot summers to cold winters. Choosing the right engine oil is crucial for engine protection.
| Climate Condition | Recommended Oil Type |
|---|---|
| Hot summers (above 30°C) | 10W-40 or 20W-50 |
| Moderate temperature (15°C – 30°C) | 5W-30 or 10W-30 |
| Cold winters (below 10°C) | 0W-20 or 5W-30 |
It’s also important to check if your vehicle requires synthetic or mineral oil. Most modern cars prefer synthetic oil for better performance and longevity.
Step-by-Step Guide to Changing Your Car’s Oil
1. Prepare Your Vehicle
Make sure your car is parked on a flat surface and let the engine cool down if it has been running. Engage the handbrake and place wheel chocks behind the tires for safety.
2. Lift the Car (If Needed)
If your car has low ground clearance, use a jack to lift it up and place jack stands under it for stability. Never work under a car supported only by a jack.
3. Drain the Old Oil
- Place the oil drain pan under the oil drain plug.
- Use a socket wrench to loosen the drain plug and let the oil flow into the pan.
- Allow all the oil to drain completely (this may take 5-10 minutes).
- Replace the drain plug washer (if applicable) and tighten the drain plug back.
4. Replace the Oil Filter
- Use an oil filter wrench to remove the old oil filter.
- Before installing the new filter, apply a thin layer of fresh oil to the rubber gasket for a proper seal.
- Screw the new filter in place by hand (do not overtighten).
5. Add New Oil
- Use a funnel to pour new oil into the engine through the oil filler cap.
- Check your car’s manual for the exact oil quantity needed.
- After pouring, wait a few minutes and check the oil level using the dipstick.
6. Start the Engine and Check for Leaks
- Start your car and let the engine run for a few minutes.
- Check under the car for oil leaks around the drain plug and oil filter.
- Turn off the engine and check the oil level again using the dipstick. Top up if needed.
How to Dispose of Old Oil Properly
Never pour old engine oil down the drain or into the ground, as it is hazardous to the environment. In Pakistan, you can dispose of old oil at local auto workshops, service stations, or designated waste collection centers.
Signs That Your Car Needs an Oil Change
Apart from following the recommended oil change intervals (usually every 5,000 – 10,000 km depending on your car and oil type), here are some signs that your car may need an oil change sooner:
- Dark or dirty oil – Fresh oil is amber-colored; dirty oil is black.
- Engine noise – Unusual knocking or grinding sounds.
- Decreased fuel efficiency – Dirty oil can cause reduced mileage.
- Oil change warning light – Modern cars have sensors to detect oil condition.
Common Mistakes to Avoid
Even though changing oil is simple, many beginners make the following mistakes:
- Using the wrong oil type – Always check your car manual.
- Over-tightening the oil filter or drain plug – This can cause leaks or damage.
- Not replacing the oil filter – A clogged filter can cause oil contamination.
- Not checking the oil level after filling – This can lead to engine problems.
