HOW TO CHANGE OIL IN A CAR

Definition

• Friction – This is the resistance an object encounters when its surface is moving over the surface of another object. It generates wear and heat.
• Oil filter – this is a device that filters oil to remove contaminants in an engines oil system.

Introduction

Vehicles are very important in our lives. They ferry us from place to place and they also carry goods for us. But like any other machine they require maintenance, this includes checking and fixing several parts from time to time. Another very important routine maintenance in a car is changing oil. The process of changing oil involves removing the old oil from the vehicle’s engine and adding fresh oil.

The reason why changing oil in a vehicle engine is important is because as the engine parts move they rub against each other and create friction which generates heat and wear in the parts. Now the oil in an engine lubricates the moving parts reducing friction and wear and at the same time absorbing the heat generated and hence ensuring that the engine parts work together effectively and efficiently.

After a period of time the oil in the engine breaks down and its quality deteriorates, this is due to the dust and other contaminants. Hence the oil is not able to lubricate the engine parts and absorb the heat generated. Therefore if you own a car you need to change the oil before it looses its quality. Changing oil is done often depending on the manufacturers specification.

Precautions

1. Use protective equipment such as gloves and an overall since sometimes oil changing can be messy.
2. If you need to jack up the car to get under it using a jack, make sure the car is secured with jack stands. Do not get under the car if it is not secured.
3. Use the right tools for the right job.

Procedure

Step 1 : What you need.

1. Correct amount and weight of fresh oil as specified in the cars manual.
2. Correct new oil filter.
3. Oil catcher pan.
4. Oil filter wrench.
5. Funnel.
6. Jack and jack stands. (if needed)
7. Right size spanner.

Step 2 : Jack up the car.

If it is not possible to get under the car raise the car using the jacks at appropriate lift points, as specified in the car manual. As shown below.[pic 1]
