Does my car need to use the genuine manufacture’s oil?

Should I use the manufacturer’s oil in my car?

Changing your engine oil regularly enhances smooth running of your vehicle. It is also one of the best ways of maintaining your vehicle. Engine oil does not allow the metal parts in the engine rub against each other, thus reducing wear and reducing heat. Changing your engine oil sporadically reduces your vehicle’s lifespan. Depending on the auto mechanic consulted, servicing your vehicle’s engine oil is expected to last for at least 10,000kms (sometime longer depending on the car). However, this depends largely on how frequently the vehicle is used, engine oil quality and the vehicle’s age amongst others.

One of the best ways of properly maintaining your car is using the right engine oil for your vehicle. Most vehicle manufacturers do provide detailed information about the particular engine oil the vehicle should use in the owner’s manual.

Function of engine oil

Internal combustion engines are designed with several metal moving parts inside them. These parts comes with bearings at any point where metal parts rub against each other. Bearings are used for several reasons. The bearing’s metal parts are a bit softer than others. And for this reason, it is the bearings that wears, and not the larger parts. Bearings comes in a wide range of sizes so that they can fill excess space in your engine parts. Changing your engine oil fills the excess space between those metal parts, thus reducing wear and improves lubrication.

Choosing quality oil

When planning to change your oil, the first thing to consider is quality. There are several quality motor oils on the market today. However, picking car manufacturer’s rated engine oil is recommended as they are independently tested and proven to outlast other oil ratings.

Oil Viscosity

You don’t necessarily have to pick genuine manufacturer’s oil.  In fact there are a number of vehicle manufactures nowadays that use high quality long life oils sourced from Castrol and Penrite (etal).  Another important factor to consider is the viscosity, which refers to a liquid’s ability to flow, that’s just perfect for your vehicle’s temperature and your climate. The viscosity of the oil determines how well the oil can flow at any given engine temperature. When the engine is cold, you need the oil to be able to run freely to provide the engine protection it needs and when the engine is at full operating temperature, the engine oil must not become too thin and runny which also will not protect your engine properly.

Engine Oil API Rating

You must use an engine oil with the correct API (American Petroleum Institute) rating to suit your vehicle’s engine and year of manufacture.  Check your owners manual to ensure your using the correct API rated oil for your car.


Oil is very important when it comes to smooth running of your vehicle and for this reason it is highly recommended to go for the best engine oil available on the market. Remember to makes sure the oil has just the same characteristics required for your vehicle as stated in the owner’s manual.
