Your car’s engine works hard every day. Inside the engine, many metal parts move fast and create heat. Engine oil keeps those parts smooth and cool. When oil gets dirty, it stops protecting the engine. That is why knowing how to change oil in car is one of the most useful skills for any driver.
Many mechanics say the same thing after years in the garage. Most engine problems start because old oil stayed in the engine too long. Fresh oil protects your engine, improves fuel use, and helps your car last longer.
The good news is that an oil change is simple. With a few tools and some patience, you can do it at home.
What Is an Oil Change and Why It Matters
An oil change means draining old engine oil and replacing it with fresh oil and a new oil filter. This process keeps your engine clean and protected.
Why engine oil matters
Oil performs several important jobs inside your engine.
• Lubricates moving engine parts
• Reduces heat inside the engine
• Removes dirt and metal particles
• Prevents engine wear
When oil becomes dark and thick, it cannot protect the engine well. That is when problems begin. Most cars need an oil change every 5,000 to 10,000 km depending on the oil type and driving conditions.
How to Check Oil in Car Before Changing It
Before you change oil, you should check the oil level. This takes less than one minute.
Follow these steps
- Park your car on level ground.
- Turn off the engine and wait a few minutes.
- Open the hood and find the oil dipstick.
- Pull it out and wipe it clean.
- Insert it again and remove it to check the level.
The oil should sit between the minimum and maximum marks.
