Motor oil is something that connects both car lovers and everyday drivers. It’s like the lifeblood of your car, helping the engine run smoothly and last longer. Even though it’s super important, there are a lot of myths about motor oil that can confuse even the most experienced car owners.
In this guide, we’re going to clear up those myths and share the real facts about motor oil. As cars get more advanced and there are more types of oil to choose from, it’s more important than ever to know what’s true and what’s not. This is all about helping you make better choices for your car by giving you the right information.
What is Motor Oil and Why Do We Need It?
Motor oil (also called engine oil) is a special liquid that helps your car’s engine work better and last longer. It does a few really important jobs:
- It keeps engine parts from rubbing too hard against each other.
- It helps stop the engine from getting too hot.
- It keeps everything running smoothly.
Motor oil also helps clean the engine by picking up dirt and tiny bits of metal. It protects the engine from rust and damage, too. Think of motor oil as the engine’s helper—it works quietly in the background to keep everything running right.
Without motor oil, the engine could break down quickly, get damaged, and cost a lot to fix. That’s why it’s super important to always have the right oil in your engine.
Now, let’s check out some of the common myths people believe about motor oil—and find out what’s really true.
Myth 1: All Engine Oil is the Same
Some people think that all motor oil is the same and that you can use any kind in any car. But that’s not true—and it can actually damage your engine.
Fact: Different cars need different kinds of oil. Some oils are thicker, and some are thinner. Some have special ingredients that help clean the engine, fight rust, or stop it from overheating. Car makers usually tell you which oil is best for your car. So, always check your car’s manual or ask an expert to be sure you’re using the right one. Using the wrong oil could damage your engine or make it wear out faster.
Myth 2: Dark Oil Means It’s Dirty and Needs Changing
A lot of people see that their engine oil has turned dark and think it’s dirty and needs to be changed right away.
Fact: Motor oil gets darker over time because it’s doing its job—cleaning and protecting the engine. The colour change doesn’t always mean it’s bad or used up. Today’s motor oils have special ingredients that help them last longer and work even when they’re dark. Instead of just looking at the colour, it’s better to follow your car’s recommended schedule for oil changes or get the oil tested if you’re not sure.
Myth 3: Synthetic Oil Can Make Old Engines Leak
Some people say that if you use synthetic oil in an old engine, it will start to leak. They think the oil is too strong and will wash away stuff that was helping to block leaks.
Fact: That might have been true a long time ago, but not anymore. Today’s synthetic oils are made to work safely in both new and old engines. They clean the engine and protect it without hurting the seals. If an engine starts leaking after switching to synthetic oil, it probably already had a problem—the oil just made it easier to see. So don’t worry! Synthetic oil is safe and actually really good for keeping engines clean and running well. Just make sure to check your engine often, especially if it’s older.
Myth 4: You Have to Change Your Motor Oil Every 4,500 Kilometres
A lot of people still believe you must change your oil every 4,500 km, no matter what. It’s something that’s been passed down for years, like an old rule that never goes away.
Fact: That rule is outdated. Today’s engines and motor oils, especially synthetic ones, are much better than they used to be. Many cars can go 12,000 km or more before needing an oil change. Some even go up to 24,000 km! Every car is different, so it’s best to check your car’s manual to see what the manufacturer recommends. Changing oil too soon isn’t just a waste of money—it can also create more pollution. So please don’t change it too early; change it when your car actually needs it.

Myth 5: Thicker Oil Protects Your Engine Better
Some people think thicker oil is always better because it looks stronger and heavier. They believe it can protect the engine more, especially if the car is old or making strange sounds.
Fact: Thicker oil isn’t always better. If it’s too thick, it might not move around the engine fast enough, especially when it’s cold. That means it can’t protect the engine parts properly. On the other hand, oil that’s too thin might not work well when the engine gets really hot. The best oil is the one that your car’s manufacturer recommends—it’s made to match your engine perfectly. If you’re not sure which one to use, ask a mechanic before making changes.
Myth 6: You Can’t Switch Between Synthetic and Regular Oils
Some people think that once you start using either synthetic or regular oil, you have to stick with it forever. They believe switching between the two can damage the engine or make the oil not work right.
Fact: It’s actually fine to switch between synthetic and regular oil as long as the oil matches what your car needs. Both types of oil are designed to work together. Some oils are even made by combining both types! The key is to make sure the oil you choose works for your car. If you’re unsure, ask a mechanic to be sure.
Myth 7: Motor Oil Has to Be Changed When It Turns Black
If the oil turns black, it’s usually a sign that the cleaning additives are working. The best way to know when to change your oil is to follow the guidelines in your car’s manual. For more exact timing, you can even have the oil tested to see when it really needs to be changed.
Fact: Not always. Oil turns black naturally as your engine runs. This happens because the oil gets hot and picks up dirt and debris, which the oil keeps from sticking to engine parts. This means the oil is doing its job!
Key Takeaways on Motor Oil
- Specificity Matters: Not all motor oils are the same. Different cars need different oils. Using the right one makes a big difference in how your car performs and how long it lasts.
- Colour Isn’t Everything: If your oil looks darker, it’s not always a bad sign. It just means the oil is doing its job by cleaning and protecting your engine.
- Modern Synthetics: Today’s synthetic oils are made to work well in all kinds of engines, even older ones. They often protect the engine better than regular oil.
- Re-evaluate Old Rules: The old rule about changing oil every 4,500 km isn’t always needed anymore. Many cars can go much longer before needing a change.
- Viscosity Counts: The thickness of your oil matters. Using the wrong thickness can damage your engine. Always use the oil your car’s manual recommends.
