Everything You Need to Know about Car’s Engine Oil

Engine oil is a critical component of the engine. It lubricates and cools the moving parts and provides corrosion protection. The oil pump circulates the engine oil throughout the engine, where it absorbs heat from friction between moving parts, and then returns to the oil pan for cooling before going back out to the engine again.

Engine oils are formulated with a viscosity (thickness) that is dependent upon their service category. Oil viscosities range from 0 weight (W) at low temperatures to 25W at high temperatures. These numbers indicate how easily the oil can flow through small passages in an engine — higher numbers mean more viscous (thick) oils that don't flow as easily at low temperatures; lower numbers mean less viscous oils that will flow easier at high temperatures.

The main function of changing your car's engine oil is to remove contaminants that build up over time and cause damage to your car's internal components including:

When should you change your car's engine oil?

In most cases, the manufacturer recommends changing your oil every 5,000 miles or six months. However, this is not an exact science. The actual interval depends on several factors including:

Your driving style (stop-and-go traffic vs highway driving)

How much you drive (high mileage drivers will change their oil more often)

If you live in a cold climate, you'll need to change your oil more frequently because the oil thins with temperature and can wear out your moving parts more quickly.

How often you check your oil level and change it when it's low also affects how often you should do so. Many newer cars have systems that monitor the condition of the oil and warn you when it needs to be changed. Your owner's manual will tell you if this applies to your vehicle.

What is the purpose of changing your vehicle's engine oil?

Changing your car's engine oil is a way to keep it running smoothly and efficiently. When you drive, particles from the road like dirt and sand get inside your car's engine and cause wear on its moving parts. Oil catches these particles and helps protect them from the heat generated by friction. To keep everything working properly, you need to clean off these particles with new oil every few changes.

How often should I change my vehicle's engine oil?

The most important thing to remember about changing oil when you rent a car from rentalcarsuae.com is that it needs to be done regularly. The manufacturer of your car will usually recommend how often it should be changed in their owner's manual, but this varies based on factors like what kind of driving conditions you experience (city vs freeway) as well as how many miles per year you put on the vehicle. You can also check with an automotive technician at an auto supply store or dealership for recommendations.
