Should You Change Your Oil? The Next 5 Signs You Need One

If you’re reading this article, it’s likely that you’ve heard about oil changes and are wondering if now is the right time for one. Well, I’m here to tell you: yes, it definitely is! But before we get into why an Oil Change Christchurch is so important and what to look out for when deciding whether or not to schedule one, let’s start with some basics.

Signs when you Need to Change Your Oil:

  1. Engine not running smoothly

You may notice that your engine isn’t running as smoothly. It could be hard to start, or it might make loud noises, but this is a sign that the oil is dirty and needs to be changed.

If you don’t change your oil regularly, it can cause major damage to the engine. The longer you wait between changes, the more likely it is that there will be sludge buildup inside your car’s engine, which can cause irreversible damage if left untreated. This means that not changing your oil regularly will eventually result in costly repairs down the road!

  1. Check the engine light flashing.

If you’re driving a car and the check engine light starts flashing, that means your vehicle needs attention.

The check engine light is a warning sign that your car needs attention. If it’s flashing, this means there’s something wrong with your vehicle, and it could be serious. 

It could also just be a minor problem like a loose gas cap or low oil level, but either way, it’s best to get it checked by a Mechanics Christchurch as soon as possible because ignoring these issues can lead to further damage and an expensive repair bill down the road.

If you notice that your check engine light has been on for a while (i.e., more than 2 days), then it may be time for an oil change!

  1. Noisy engine

If your engine is making noise, it’s usually a sign of some kind of problem.

In general, noisy engines can be caused by the following:

A worn-out engine. This is especially true if you’ve had your car for more than six years and are starting to see signs of oil leaks or other cosmetic issues. It’s also common if you do a lot of highway driving—your engine may wear down faster because it’s under higher stress conditions.

Low oil levels in the car’s tank (also called low-oil pressure). This is often caused by an old filter that hasn’t been changed in a while; it might be clogged up with dirt and rust particles, so the oil isn’t getting through properly anymore!

Blocked filters on other parts (like air cleaners). These filters keep contaminants out of the air intake system but can become clogged over time from dust accumulation inside them.

  1. The oil colour is dark and not transparent.

Oil Change Christchurch is a good idea if your oil is dark in colour or not transparent. If it’s dirty with dirt and gunk in it but not burnt, then that’s normal. When you’re checking the appearance of your oil on the dipstick, make sure it’s clean and clear—if it looks like chocolate milk or motor oil (and not just motor oil), then you should probably get an oil change.

  1. Smoke coming out of the engine

The first sign of oil-related trouble is smoke coming from your vehicle. This may be due to a blown head gasket, leaking valve cover seal, cracked or otherwise damaged cylinder head(s), a faulty intake manifold gasket and even a leaky oil pressure sensor. 

Additionally, if you start to see excessive smoke under heavy acceleration or deceleration, this could be an indication of a turbocharger failing.

If the smoke is only present when you start up your car in the morning, then it’s likely an issue with the engine cooling system (such as coolant flowing through the radiator).


We hope we’ve helped you decide whether or not you need an oil change. If your vehicle is exhibiting any of the above symptoms, it’s probably time for one.
