Key Highlights:


  • Changing your oil and filter is one of the most cost-effective and straightforward ways to keep your car in good condition.
  • Ignoring this can lead to major engine issues, and fixing that could cost lakhs. A ₹3,000 service is better than a ₹1.5 lakh repair later.
  • The car gives clear hints when it requires fresh engine oil. NEVER ignore them.

Why is Engine Oil So Important?


Let's consider a simple analogy. Consider how the human body relies on blood to function properly. For your car, that “blood” is the engine oil. Without it, the engine parts will rub against each other, producing immense friction. And when metal keeps rubbing against metal, you can imagine the damage the parts will incur.


Engine oil keeps everything smooth, reduces heat, and ensures your car doesn’t break down prematurely. If you have ever seen a car broken down on the side of the road with smoke coming out, chances are the owner ignored the oil change interval. So, whether or not you care about all the fancy stuff like a hi-tech music system, at least don’t mess with engine oil.


What is an Engine Oil Filter?


Now here’s the catch. Even if you put fresh, high-quality engine oil in, after some time, it gets dirty. It collects dust, carbon, and various tiny particles from the engine. That’s where the oil filter comes in.


The oil filter’s job is simple. It cleans the oil before it is returned to the engine. If you don’t replace the filter, the dirty filter will spoil the new oil. That’s why when you go for a full service, both oil and filter change are done together. In fact, it can be said that it's a must to change the oil filter every time you replace the engine oil.


Car Oil Change Frequency – How Often to Replace Engine Oil?


Now the big question: What is the right car oil change frequency? Some people say once a year, some say after 10,000 km, and some say every 6 months. Honestly, it depends on how you drive and the type of oil you use. Let's simplify it:


  • If you use synthetic oil and drive mostly on highways, you can expect to go 10,000-15,000 km or one year.
  • If you use regular mineral oil and drive in city traffic, then 5,000-7,000 km or every 6 months is better.
  • In fact, to avoid any confusion, simply check your car’s manual once. No one likes reading that boring book, but it has all the correct info.

Engine oil is cheap compared to engine repairs. It's better to change on time than regret it later.


Signs Your Car Needs an Oil Change


Sometimes the car itself starts showing the signs of oil going bad. Just notice these signs:


  • Strange engine noise, like knocking.
  • A burning smell in the car.
  • Too much smoke from the exhaust.
  • Low oil level when you check the dipstick.
  • Dashboard warning light (that small oil can symbol).

If you see these, don’t wait for the “next service”. Just get it done immediately.


Why Oil and Filter Change is So Important


Here are some of the benefits:


  1. Longer Engine Life - Your car runs smoother and lasts longer.
  2. Better Mileage - Who doesn’t want to save fuel with today’s prices?
  3. Good Performance - You can feel the car accelerate faster and drive more quietly.
  4. Less Pollution - Fresh oil means cleaner emissions.
  5. Peace of Mind - You won’t be scared of sudden breakdowns.

Honestly, it’s such a small thing, but it gives so many advantages.


What Happens if You Ignore It?


If you don’t change the oil and filter on time, the following could potentially happen:


  • Dirty oil turns into sludge and blocks the engine.
  • Metal parts grind against each other, resulting in huge repair bills.
  • The engine overheats and sometimes even seizes.

And the worst part? An engine rebuild can cost lakhs of rupees. Compare that to ₹3,000-₹5,000 for a simple oil and filter change. Do you think it's worth taking the risk?


Some Simple Tips


  • Always use genuine oil and filters. Avoid buying cheap, fake ones.
  • Stick to the recommended car oil change frequency.
  • Check the oil level monthly - takes just 2 minutes.
  • If you drive in extreme heat, dust, or heavy traffic, consider changing your oil more frequently.
  • Never change oil alone - always replace the filter too.

Oil Changes: The Cheapest Insurance for Your Engine


Cars are like humans. If we eat junk food and don’t take care, we fall sick. The same is true for cars; if you don’t perform a timely oil and filter change, the engine will suffer. It may sound like a tedious maintenance task, but honestly, it’s the cheapest way to keep your car healthy for years. Don’t be lazy or miserly here. Spend a little now to save a lot later.


So if you are reading this and can’t remember the last time you changed your oil… maybe it’s already time.
