Why Does Your Car Need Oil?

Let’s first establish why your car needs oil, then we can address the oil filter conundrum. Numerous vital processes that keep the engine running efficiently in your car depend on oil. Consider oil as the lifeblood of the engine, the beating heart of your car. Its main function is to lubricate all of the engine’s moving components, including the pistons, camshafts, and bearings. This lubrication ensures that these parts function as a unit by minimising wear and friction.

Additionally, engine oil is essential for heat dissipation. Your engine produces a significant quantity of heat when it runs. In order to avoid overheating and possible engine damage, the oil assists to absorb and spread this heat. Oil also serves as a cleaning agent, clearing the engine of dirt, debris, and potentially dangerous particles. Capturing these impurities and keeping them suspended, it stops them from harming important components. Modern engine oils also frequently contain chemicals that aid in neutralising acids and preventing corrosion.

Therefore, oil is essential to the operation of your car’s engine since it offers lubrication, heat management, cleaning, and resistance to wear and tear. Your engine will continue to run at peak efficiency and will have a long, healthy lifespan if you execute routine oil changes.

Explain The Role Of The Oil Filter In A Car

The engine health of your car is significantly impacted by the oil filter, a little but crucial auto part. Its main duty is to protect your engine from potential damage brought on by impurities in the engine oil by acting as a guardian. Your engine produces heat and friction when it runs due to the numerous moving parts. Within the oil, this environment may develop microscopic metal fragments, filth, and sludge. The oil filter comes into play at this point.

The oil filter’s porous construction, which often consists of paper or synthetic fibres, allows oil to pass through while retaining undesirable particles. You can think of it as a gatekeeper that only lets clean, debris-free oil pass through to vital engine parts. This keeps abrasive impurities from creating accelerated wear and damage, ensuring that your engine runs smoothly and effectively.

In essence, the oil filter increases performance, increases engine lifespan, and adds to the overall dependability of your car. In order to keep your car working at its best, it is crucial to comprehend and manage this seemingly simple component.

Can You Change Oil Without Changing Filter In A Car?

We have already mentioned above that it’s possible to change car oil without changing the filter. An oil filter also plays an important role in retaining the engine oil pressure. If your oil filter is clogged, the engine oil won’t be able to move freely and this will reduce its pressure. Moreover, the pressure relief valve of an oil filter also plays a vital part by ensuring the pressure doesn’t get too intense. However, the filter is important in keeping the car oil that runs through the engine clean. It is pertinent for the oil filter to be in perfect working condition.

If you’re wondering can you change oil without changing filter? Then, read your car’s manual to see the kilometres mentioned before a replacement is needed. Generally, car manufacturers suggest changing the oil filter after every other oil change or after 10,000 to 15,000 kilometres. However, in extreme driving conditions, you must change the oil filter more frequently every 5,000 kilometres. Extreme driving conditions include but are not limited to:

  • Dealing with stop-and-go traffic frequently
  • Driving in extreme heat or cold
  • Driving on dirt roads or under dusty conditions
  • If your vehicle regularly tows heavy load

You can definitely change car oil without changing the filter but most car experts agree that spending a little more money to keep your car in perfect condition is better than saving a few dirhams.
