When was the last time you looked at the oil in your car’s engine?
Don’t worry if you’re not sure; you’re not the only one. A lot of car owners forget this simple but important part of taking care of their cars. But not changing the oil can slowly hurt your engine’s health and performance.
Let’s look at the five signs that your car needs an oil change right away. This will help you protect your engine, save gas, and keep your car running better for longer.
1. Your engine is louder than normal
Your car’s engine is a very precise machine, and oil is what keeps it running. It keeps all the moving parts from getting too much wear and tear by reducing friction. But oil loses its ability to lubricate when it breaks down or gets dirty.
What you might hear:
- A knocking or ticking sound when you start the engine
- A louder engine, especially when you speed up
- A rougher, more aggressive idle
This usually means that the oil isn’t doing its job of protecting the engine anymore. It’s time to listen and schedule that oil change if your car is “talking back” louder than usual.
2. Your Oil Change Light or Check Engine Light Is On
There is a reason why modern cars have dashboard alerts. Don’t ignore your oil change reminder or, even worse, your check engine light.
These lights mean that:
- Your oil level is too low
- Your oil is too dirty
- There may be a leak or a problem with the sensor
Tip: Always look in your owner’s manual to see how often the oil should be changed. Many car makers say that you should change the oil in your engine every 5,000 to 7,500 miles, or sooner if the conditions are really bad
3. Dark, Dirty Oil on the Dipstick
Here’s a quick do-it-yourself check:
- Find a flat place to park your car and let the engine cool down..
- Take out the dipstick, clean it, and then put it back in and take it out again.
- Look at the oil’s colour and texture.
If it looks thick, gritty, or black, it’s time to change it.
A clean engine oil makes the engine happy. Oil that is dirty? It’s like asking your engine to run a marathon in sneakers that are full of mud.
4. Excess Exhaust Smoke
It’s normal for your tailpipe to let out a little smoke, especially on cold mornings. If you see bluish or grey smoke, though, it’s a sign that something is wrong.
This could mean that:
- The engine is burning off old oil
- The piston ring or valve seal is worn out
- Oil is leaking into the combustion chamber
This is bad for your engine and makes your emissions worse. It might even fail a smog test. Changing the oil in your car’s engine quickly might fix the problem before it gets worse and costs more to fix.
5. You’ve Driven More Miles Than Recommended
This one is easy to miss, but it’s not hard. Your oil change appointment keeps getting pushed back because life is busy. But if you don’t change your oil for a long time, you could end up with:
- Less fuel efficiency
- Slower acceleration
- An overheated engine
- Even a complete engine failure
Quick rule of thumb:
- Every 3,000 to 5,000 miles for regular oil
- Every 7,500 to 10,000 miles for synthetic oil
Don’t just rely on your memory; write things down or set a reminder on your phone. Your car will run better and break down less often if you do this.
