Things to Consider When Buying Motor Oils

Engine oil is the bloodline of your car. It is essential in lubricating the engine and prevents damage and oil breakdown due to rising temperatures. When the engine has enough oil in it, it doesn’t need excessive power to run. 

To properly maintain your engine, make sure there’s enough oil. Doing so also saves you fuel and improves performance. Over time, oils tend to split, and the debris can interfere with the effective functioning of the engine. 

Insufficient oil can impact engine quality, longevity, and how it drives. If you’re wondering how often you should change your oil, it depends on the model of the car and where you drive it. The user’s manual given to you at the time of purchase will also have the details you need. Plus, you’ll see some signs that your oil needs changing.

Below are a few things that you need to pay attention to before spending money on engine oil. There are many brands advertised as the ‘best brand’ or calling Castrol as the best one. Regardless of any merit in these statements, they might not be relevant for your car. 

The best motor oil for your car will depend on your car model, oil viscosity, and requirements in the owner’s manual. 

Manufacturer Recommendations

A person spends a significant amount of time picking a car. The car has been through a significant investment of time and money by the people who built it to function in a specific way. 

Therefore, picking or using the wrong kind of oil can only harm your vehicle. As a result, it is important to take the manufacturer’s recommendations seriously and follow them diligently. 

Engine Oil Viscosity

The oil you put in your vehicle needs to be able to withstand both external and internal temperatures. Viscosity is the quantity of oil flowing through the engine at any given time. 

When buying the best motor oils for BMW, it is important to understand what the manual and the oil say. You want to understand the viscosity numbers – they are the numbers displayed on the bottle. 

If the number is 10W-40, the first portion of the number refers to how much winter temperature the oil can handle, and the second number shows how much oil flows when the car is running. 

When the car starts, oils should normally operate between 195 to 225 degrees Fahrenheit. The lower both these numbers are, the better it will withstand extreme temperatures. The right viscosity for your oil will either be on the bottle cap or in the owner’s manual. 

What Viscosity Should You Be Looking For?

Buying a heavier oil than the ones recommended in the hopes that it will give your car better protection is a bad idea. While older cars used heavy oils, the cars currently built are designed to use lighter oils (5W-20). It is to allow for better flow between tight parts. 

Heavy oils do not reach the engine during winter. Using lighter oil also promotes better fuel economy. Picking the best motor oils for BMW, which is both the right viscosity and has an API approval, is ideal. 

The viscosity is often decided by the manufacturer and published in the manual. A few factors have been considered before labeling it as the best motor oils for BMW. These factors are: 

  • External temperatures: If you live in a place with extreme summers and winters, you will need a different oil.  
  • Operating temperature: This is the temperature that your vehicle runs on
  • Engine load: You have to take into consideration how much stress gets put on the engine. Cars and trucks have different stress loads. 

The various kinds of oil for gas engines available in the market are 5W (20/30) and 0W-20, whereas diesel engines have 15W-40 and 5W-40.

Types of Motor Oil

There are three kinds of best motor oils for BMW – regular/conventional oil, synthetic oil, and synthetic-conventional blend. The manufacturers normally recommend regular oil for new cars. 

When using conventional oils, the ideal time to change them is in intervals of 3,000-4,000 miles.

Completely synthetic oil is ideal for high-performance engines. It is recommended for cars with higher RPM limits, temperatures, or in cases of higher loads. A synthetic blend is a combination of conventional and synthetic. 

If you cannot afford a completely synthetic best motor oil for BMW, you can pick a blend suited for your car engine. The design of high mileage oil is ideal for engines with over 75,000 miles on the clock. 

When buying the best motor oils for BMW, the 

factors to keep in mind are your driving style and additives used. For people who prefer fast cars, own sports cars, or are used to higher loads, it is ideal to obtain a special oil. Highly stressed engines require completely synthetic oil.  

The additives used in motor oils differ from brand to brand. A majority of products use mixtures of anti-foaming and anti-wear agents, conditioners, corrosion inhibitors, detergents, dispersal, and antioxidants.

Why Oil Additives?

The best motor oils for BMW are like pancake syrup. It cannot work well without proper blending and adding additives. Think of additives like vinegar for your pickles. It holds everything together and makes sure it works well. 

Oil additives are vital to ensure effective lubrication and long-term use of motor oil in current engines. In the absence of additives, the engines will quickly damage. The engine oil will also break down and clog the engine.


Why is viscosity important for motor oil?

The design for the viscosity of an oil is based on load and speed conditions. Having the proper viscosity for the oil is crucial in providing resistance to motion and saving fuel. Using heavy oil can cause metal-on-metal contact and damage the engine. 

The viscosity of oil also depends on the external temperature and the operating temperature of the car. They become thin during summer and think during winter. 

Therefore, when you pick the best motor oils for BMW, you should pick one that works well in both weather conditions.

Does motor oil expire? How long does motor oil generally last?

Motor oils do not typically have expiry dates and can last for years. The expiry also depends on the brand. E.g., Valvoline motor oils do not have expiration dates. When oil is stored in optimal conditions, it can last very long.

You can continue to use it if the American Petroleum Institute (API) rating on the label meets the manufacturer’s recommendation. Shake well before use. 

Does motor oil ever wear out or only get dirty?

The best motor oils for BMW do disintegrate. As the additives get consumed, the by-products build up in the engine and can clog it. Therefore, regularly changing your oil becomes crucial to improve engine performance. 

Follow the instructions in the manual and change as often as recommended. 

Are conventional motor oils natural and unprocessed?

The conventional motor oils have a petroleum base; however, they have been refined extensively. The base oils contain additives and properties such as anti-wear, friction reduction, and long life. 

Should I do my first oil change early on my brand new car?

We do not recommend changing your oil early on your new car. Many car owners change their oiling schedule by changing their oil early. The basis of changing the oil early is to remove any break in contaminates in the first couple hundred or thousand miles. 

However, it is baseless to do so as the pollutants are collected in the oil filter and not in the engine oil. Therefore, changing oil early in a brand new car is unnecessary. 

Why is the cleaning ability of an engine oil important?

Having clean engine components is vital in keeping the engine in pristine condition. If the engine components are untidy, the engine’s lubrication might not happen effectively. Debris can build up and clog the engine. 

The purpose of engine oil is to protect engines for improved performance.

Why is the choice of engine oil so important?

Your car engine cannot function well without the best motor oils for BMW. If you use the wrong kind, the engine is at a higher risk of damage and corrosion. If there are blockages in your engine, it can lead to engine seizure. 

With the right oil, you can drive confidently and not worry about engine damage. You just have to make sure you check the manual for the recommendations and change it often. 

Is it important to, and how often should I change the oil?

It is vital to change your oil filter, as the company recommends, at or before the end of oil-change intervals. The manufacturer recommends these changes based on distance traveled or time. If you want to keep your engine in good condition, regularly changing oil is vital. 

What is the key to engine protection for winter weather?

As previously mentioned, oils change viscosity in summer and winter. As oils tend to become thicker during winter, finding oil that works well in extreme conditions is necessary. 

Before you start your vehicle in winter, make sure you check temperatures, oils, transmission, and hydraulic system. Ensure that you use the dipstick to check oil levels and other fluids using appropriate methods. 


Motor oil is crucial for all vehicles. Regularly changing your oil is a vital part of the maintenance of your car. 

Picking the right oil is an important choice for the longevity of your car. We are here with the information you need to take care of your car. The easiest way to get the best oil for your car is to read the owner’s manual.

It can be hard to make the right choice but ensure you have all the right information you need by doing the research necessary.
