Regularly changing the oil in your car has so many benefits. From helping the car to run smoother to keeping your engine going for longer, changing the oil can do your car a world of good.

If this is ignored for too long it could be too late. However, changing the oil isn’t too difficult but it’s not the cleanest job. At WeBuyAnyCar, we have compiled a list of the benefits of regularly completing oil changes and how to complete an oil change to keep your car running smoothly.


Benefits of Regular Oil Changes

Regular oil changes are important for several reasons:

  • Engine lubrication: Oil lubricates the various moving parts within the engine, such as the pistons, crankshaft, and camshaft. This reduces friction and wear, helping to extend the lifespan of your engine and prevent premature failure. Over time, oil breaks down and becomes less effective at lubricating, which is why regular oil changes are necessary to maintain proper engine lubrication.
  • Heat dissipation: Oil also helps to dissipate heat generated by the engine during operation. As the engine runs, it generates heat from the combustion process. The oil absorbs this heat and carries it away from the engine, preventing it from overheating. Over time, oil can become less efficient at heat dissipation due to contaminants and degradation, which can lead to increased engine temperatures and potential damage.
  • Contaminant removal: Oil picks up dirt, debris, and other contaminants that accumulate within the engine over time. This includes metal particles, dust, and sludge. If not removed through regular oil changes, these contaminants can accumulate and form deposits that can hinder engine performance, reduce fuel efficiency, and increase the risk of engine damage.
  • Engine performance: Fresh, clean oil helps to maintain optimal engine performance. It promotes the smooth operation of the engine, which can lead to improved fuel efficiency, better power output, and reduced emissions. Regular oil changes can help to keep the engine running at its best and prevent loss of performance over time.
  • Manufacturer's recommendations: Most car manufacturers provide guidelines on oil change intervals based on factors such as the type of oil used, driving conditions, and vehicle model. Following the manufacturer's recommendations for oil changes is important to ensure the engine is properly maintained and to comply with warranty requirements.

To change the oil in your car, you will need a few things. You will need the following:

  • Fresh oil
  • A new oil filter
  • A wrench
  • Drain pan
  • A funnel
  • And something to clean up any spillages

You will also need to check what type of oil your car needs. If you aren’t sure what oil you need, check out Halford’s oil finder.

How To Complete an Oil Change

  1. Park your car on a level surface and let the engine cool down for a while to avoid burns from hot oil. If needed, raise the car using a jack and jack stands to access the oil drain plug and oil filter easily. Consult your owner's manual for the proper jack points and use caution when working under a raised vehicle.
  2. The oil drain plug is usually located on the bottom of the engine oil pan. Place the drain pan underneath the drain plug to catch the old oil.
  3. Using a wrench or socket set, carefully loosen and remove the drain plug, turning it counterclockwise. Be prepared for the oil to start flowing as soon as the plug is removed. Allow the old oil to drain completely into the drain pan.
  4. Locate the oil filter, which could be on the side or underneath the engine. Use an oil filter wrench to loosen and remove the old oil filter, turning it counterclockwise. Be sure to have a drain pan underneath to catch any oil that may spill. Clean the area around the oil filter mounting location, and then install the new oil filter, following the manufacturer's instructions.
  5. Once the old oil has finished draining, clean the drain plug and install a new crush washer, if applicable. Carefully thread the drain plug back into place by hand, and then use a wrench or socket set to tighten it snugly, being careful not to over-tighten.
  6. Use a funnel to pour the recommended amount and type of fresh oil into the engine oil filler hole, as specified in your owner's manual. Double-check that the oil level is within the proper range on the dipstick.
  7. Wipe any spilt oil, reinstall the oil filler cap, and check around the drain plug and oil filter for any signs of oil leaks. If any leaks are detected, address them immediately.

Used motor oil is considered hazardous waste and should be disposed of properly at a designated oil recycling centre or a service station that accepts used oil. Do not dump used oil into the environment or pour it down the drain.

If you are unsure of how to complete an oil change or don’t have the right tools, you can take your car to a garage and a technician will be able to help. Also, when you get your car services, an oil change is usually included.
