How to choose the best engine oil for your car

Taking care of a car engine is a highly serious duty for any automobile owner. You should thus be able to select the ideal engine oil for each given vehicle.

Engine oils are formulated to function a vehicle engine effectively and are like blood for automobile engines. Every internal combustion engine is doomed without oil. But what actually does engine oil do? What kind of engine oils are available, and how can you select the best for your car?

What does engine oil do?

It’s an excellent place to start if you realize that engine oil’s function is to lubricate moving parts. However, it has many other functions besides lubrication, and they are crucial considerations when choosing the best oil for your needs.

Corrosion is defended against by engine oil. Oil is applied to the metal components inside the engine to stop oxidization, which would soon lead to degradation.

It removes sludge. Detergents in clean engine oil help break down sludge deposits and transport them to the oil filter, where they are finally caught and removed.

It creates a partition between moving components. Frictional wear is minimized by the molecular barrier between moving parts, such as a piston and cylinder wall.

What kinds of engine oil are there?

The SAE (Society of Automotive Engineers) rates engine oil grades, which are normally two digits separated by a “W.” The example of 5W30 is typical. The significance of each component of the grade is distinct.

  • The flow rate at -18 degrees Celsius is represented by the first number, which is 5 in the yellow box on the lower right in the image above. In chilly temperatures, it flows more readily the lower the first number.
  • Winter is represented by the second component, the W, which is connected to the first number in the series.
  • The last component, the 30 in the Castrol Edge 5W-30 graphic above, is a two-digit value that represents the viscosity of the oil at 100 degrees Celsius. The less prone it is to thinning out at high temperatures, the higher the number.

What’s the difference between types of engine oil?

Obviously, oil is more complex than merely its grade. Engine oils are categorized into three groups.

Deep below crude oil is processed to become “Conventional Oil.” After waste materials are taken out, the mixture is combined with additives such detergents, rust inhibitors, anti-wear agents, and friction modifiers. Although certain contaminants are still present, molecules vary in size and form.

Contrary to common misconception, “Synthetic Engine Oil” is manufactured from the same raw crude oil and is not a product of a lab. More contaminants are eliminated during the more rigorous refining process, which also results in molecules with more uniform shapes and sizes. It typically has superior quality or higher-performing additives and operates better in both hot and cold temperatures.

“Semi-Synthetic Oil” is a mixture of synthetic and traditional oil. It performs more effectively than traditional oil without costing as much as full-synthetic oil.

Which engine oil should choose?

Then, how can you pick the finest oil for your automobile based on the aforementioned classifications? Here are some suggestions and illustrations.

Choose a slope with a reduced pour rate in cold weather for driving. The oil grade starts with this number. A 5W30, for instance, will flow more smoothly in the winter than a 10W30 or 15W40.

The last figure is the oil viscosity in heat. For summer driving, your engine is better protected with an oil that has a greater viscosity in heat. In hot regions, 5W30 oil will perform better than 5W20 at preventing wear and oil breakdown in your engine.

Is the brand important?

The brand you select frequently determines the quality of the part in the package for brake parts like brake pads and rotors or suspension components like shock absorbers. Engine oils are quite unique. The majority of oil brands provide lines of conventional, semi-synthetic, and synthetic oil in different grades.

However, certain specialty oils are exclusive to particular companies. For instance, ENI I-RIDE Racing Offroad Oil addresses the challenges offroad vehicles face. For the difficulties a diesel engine encounters, Shell Helix Ultra was created particularly. For high-mileage engines, there are choices like Castrol Edge Professional Titanium and Total Quartz.

When is my engine oil change due?

Determining the right time to replace your engine oil might be difficult. The interval between engine oil changes has altered multiple times during the last four or five decades. Every 1,600 kilometers, the Ford Model T needed its oil changed!

The typical oil change interval, according to the majority of individuals, is 5,000 kilometers. But even that time frame for changing the engine oil is frequently off. Modern cars frequently incorporate an oil life monitor that takes your car’s use into account. When estimating when to replace the oil, a variety of variables are taken into account, including the number of starts, idle time, outside temperature, mileage, and more. For some cars, it may be 5,000km, while for others, it might be as high as 20,000km.

The best course of action is to adhere to the recommendations in the owner’s manual’s maintenance advice. It’s the best standard to adhere to whether it specifies a mileage interval or an oil life monitor.

What to check or change during an oil change

Of course, changing the oil means emptying the oil from the crankcase and replacing it with fresh oil of the grade and type recommended by the manufacturer. Additionally to engine oil changes:

  • Every time the oil is changed, the oil filter should be changed as well. It has accumulated sludge and impurities from the miles the vehicle has been traveled that must be cleaned out of the engine. If you don’t change the oil filter, it will ultimately clog and deprive the engine of oil, which will harm it.
  • Every time you change your oil, you should also replace any o-rings or brass washers on the oil drain plug on your car. By replacing this seal, you may get rid of annoying leaks on the floor and a loose drain stopper.
