Clean engine oil is essential for the smooth running of your car. Engine oil lubricates moving parts, regulates temperature, and prevents dirt from accumulating in the engine. Many drivers tend to ignore the oil light and wait until it illuminates to turn on the engine.
Your engine will last longer if you change the oil regularly. It also helps to minimize wear and keep your car’s performance consistent. You can take a few steps to take care of your engine and prevent expensive repairs.
This guide covers 5 essential steps to engine oil replacement. It also includes the right type of oil, common pitfalls, and the optimal time to visit a professional mechanic.
Why Engine Oil Replacement Matters for Engine Health
The function of the engine oil is not just to lubricate moving parts. It decreases metal-to-metal contact and keeps engine temperatures under control. It also conveys dirt and fine particles to the oil filter. Oil also aids in creating a proper oil seal clearance between some engine components.
With time, dirt accumulates in the oil, and some of its protective properties are lost. Old oil can also develop sludge that can negatively impact engine performance. It is important for the engine’s parts to stay protected and to prevent these issues with regular engine oil replacement.
Here are some indicators that it’s time to change the oil in your vehicle:
- Inspect for oil condition and adhere to the manufacturer’s recommendations.
- Check for leaks and excessive use of oil, and correct it.
- A knocking or ticking noise can be caused by low oil or inadequate lubrication.
- Stop safely and ascertain the problem. A red oil pressure warning should be attended to immediately.
- Look for leaks and call a professional for assistance if the odor persists.
Do not disregard an oil warning light. A little can go a long way in causing big trouble in the engine.
Step 1: Find the Right Oil and Filter for Your Vehicle
The proper oil lubricates and aids your engine in its performance. Look at your owner’s manual first before purchasing oil. It shows you the type of engine oil replacement that is recommended and the oil specifications your engine requires. Before buying engine oil, check its grade and specifications against your vehicle manufacturer’s recommendations. You can also visit OGRA Pakistan for relevant information about Pakistan’s oil and gas industry.
For instance, you could see a grade like 5W-30 or 0W-20. The numbers refer to the oil’s flow rate as the temperature changes. Do not buy oil based on the lowest price. Always buy according to the manufacturer’s recommendations.
Generally, it is possible to select among 3 primary kinds.
Conventional oil
This is an option for older engines that need traditional oil.
Synthetic blend oil
It’s a blend of conventional and synthetic oils.
Full synthetic oil
This provides excellent performance at various temperatures and can be used for extended service lives as specified by the manufacturer.
Your driving style is also important. Regular maintenance may be necessary more often due to frequent short trips, heavy traffic, extreme temperatures, and dusty roads. Select a good quality oil filter that is compatible with your car. The filter is designed to remove dirt and small particles before they are pumped back through the engine. The use of a bad-quality filter reduces the advantages of fresh oil.

Step 2: Gather Tools and Prepare a Safe Work Area
An engine oil replacement is easier and safer if you are well-prepared. Collect all of the items before starting. Typically, you’ll require:
- The correct engine oil is right and a new oil filter is installed.
- A socket wrench and the appropriate socket.
- An oil drain pan
- A funnel
- An oil filter wrench
- A new drain plug washer (if necessary)
- Gloves, protective glasses
- Properly rated jack stands, if you need to raise the vehicle
Drive on a flat surface. Apply the parking brake and turn off the engine. Allow the engine to cool down sufficiently to avoid burns. Warm oil is easier to work with, but hot oil can severely burn.
Do not use a jack as the only support for a lifted vehicle. Properly rated jack stands and follow the vehicle’s lifting instructions. Call a professional if you can’t support the engine oil replacement safely.
Do not allow children or pets to enter the work area. Before removing the drain plug, put the drain pan under the engine. Also, read local regulations about used oil disposal. Do not pour used oil down the drain or onto soil or regular household trash.
Step 3: Drain the Old Oil and Replace the Filter
To do this, first find the oil drain plug of the engine. If you don’t have an owner’s manual, look at the manuals online. Place the drain pan under the plug. Use the proper wrench to remove the plug gently. Allow the old oil to drain into the pan. Be careful with hot oil. It can still burn.
Check the drain plug and washer. Change any worn washers as necessary. Thoroughly clean the plug before reinsertion. Adjust to the manufacturer’s recommended setting. If too much force is applied, it might harm the threads and cause water to leak. Then, replace the oil filter. During this step, some oil may spill, so ensure you keep the drain pan. Make sure the rubber gasket on the old filter is detached from the filter.
Put a small amount of new oil on the rubber gasket of the new filter. Read the engine oil replacement instructions to install the filter. Many filters require hand tightening, while some designs need a specific tightening method. Before tightening, review the filter directions and the vehicle owner’s manual. Proper installation ensures no leaks and a protected engine.
Always dispose of used engine oil responsibly to protect the environment. Review the Punjab Environmental Protection Department for environmental guidance and information about waste management.
Step 4: Refill, Check Levels, and Test for Leaks
Once the drain plug and new filter are installed, put the recommended oil in the engine. Check your owner’s manual for the correct capacity. Use a funnel and pour slowly to avoid spills. If you are not sure of the capacity of the engine, do not add it all at once. Allow space for checking the level and adding more as necessary.
Park the car on flat land. Use the engine oil replacement procedure outlined in the owner’s manual to check the dipstick. Remove the dipstick, clean it, then put it back in and remove it once again. The oil level should be between the indicated limits. If the oil level is low, add a little oil. Do not exceed the maximum mark. If there is excess oil, the engine may froth and have other issues.
Start the engine and monitor the oil pressure warning light. Check for leaks around the drain plug and filter under the car. Turn off the engine and wait for the manufacturer’s instructions to check the oil level again. If you see a leak or the oil pressure warning stays on, stop the engine immediately. Correct the issue before getting behind the wheel.
Step 5: Record, Dispose, and Maintain Your Schedule
Good records will allow you to monitor maintenance and plan for your next service. Record date, mileage, oil grade, and filter information following each engine oil change. If the work is done at a workshop, retain receipts. Then take the used oil and old filter to a disposal site that recycles them or an approved disposal site. Use a clean, sealed container to store used oil until it can be safely disposed of.
Your engine maintenance intervals are dependent on your car, oil used, and driving environment. Some vehicles require an oil change every 5,000 miles or less. Others can change oil every 7,500 to 10,000 miles or more. Always follow the manufacturer’s instructions. Set a reminder for engine oil replacement depending on mileage or time. Regularly check oil level, particularly before long journeys. Regular maintenance can lead to early detection of issues and prevent costly repairs.
Other critical components are also part of regular maintenance. Inspect your brake pads to make sure they are not worn down, and inspect your tyres for damage. If you want to compare cars before your next purchase, read our guide to the best fuel-average car in Pakistan.

DIY vs. Professional Oil Change: Which Should You Choose?
If you have the proper tools and know how to change the oil, you can save money by doing it yourself. However, you do have to purchase the proper materials, work safely, and dispose of the used oil correctly. Engine oil replacement mistakes can also lead to leaks or engine damage.
A professional service provides ease and professional inspections. A technician can check for leaks, fluid levels, and other maintenance issues. If your car is still covered by its warranty, or if there is a service procedure that you need, you should also seek professional assistance.
When booking, inquire about the type of oil grade the technician will use, if the price will cover the filter, and how the old oil will be disposed of.
