What is Synthetic 5w40 Engine Oil?

Synthetic 5W40 oil and how it can benefit your car.

5W40 oil is a popular choice for many drivers, but what exactly is it? And why is it so popular? In this blog post, we’ll take a closer look at 5W-40 engine oil, including its benefits, drawbacks, and how to choose the right one for your car.

5W-40 engine oil is a multigrade engine oil, which means that it can flow easily at cold temperatures (the “W” stands for winter) and maintain its viscosity at high temperatures (the first number). This makes it a good choice for a variety of climates and driving conditions.

Some of the benefits of using 5W40 oil include:

  • Improved fuel economy
  • Enhanced engine performance
  • Protection against wear and tear
  • Corrosion resistance
  • Oxidation resistance

However, there are also some drawbacks to using 5W-40 oil, including:

  • It can be more expensive than other types of oil
  • It may not be the best choice for all engines
  • It may not provide the same level of protection as some other types of oil in extreme conditions

Overall, 5W-40 engine oil is a good choice for many drivers. It offers a number of benefits, and it is relatively versatile. However, it is important to choose the right oil for your car and your driving conditions.

What are the Benefits of 5w40 Engine Oil?

Buying a fully synthetic engine oil will cost you some extra cash, however, the money will not be paid in vain. The pack of 5w40 Synthetic Engine Oil comes with extra benefits including:

  • Enhanced Efficiency at High Temperatures

High temperatures and engine speeds don’t affect synthetic oil’s lubrication. This reduces engine wear and extends engine life.

  • Improved Cold Weather Performance

5w40 Engine oil flows well at low temperatures. This can enhance cold weather starting and engine wear.

  • Longer Service Life

Synthetic 5W40 oil lasts long. Its longer oil change intervals save time and money on the long term.

  • Greater engine wear protection

5W40 oil is developed to give superior protection against engine wear, particularly in high-performance engines

  • Exceptional protection from contaminants

Synthetic Engine oil resists breakdown and contamination, keeping your engine cleaner and more efficient.

  • Better fuel economy

Using Synthetic 5W40 Engine oil keeps the engine in good condition thus prevent excess use for diesel of gasoline.

It is important to bear in mind that not all synthetic motor oils are equal. This means that Synthetic 5w40 Oil is not just any duplicate of any other product with the same specifications.

The quality of the motor oil varies greatly depending on the quality of the base oil, the quality of the additives, Quality control process in the factory, and more.

Full Synthetic 5w40 Oil for Diesel Engines

Synthetic 5w40 diesel oil is an synthetic engine oil designed specifically for diesel engines. It comprises synthetic base stocks and a unique blend of additives designed to provide maximum lubrication and protection for diesel engines. Although 5w40 synthetic gasoline oil share many characteristics with it, the two are vastly different.

Because diesel and gasoline engines have distinct lubrication requirements, we do not suggest using 5w40 synthetic diesel oil for gasoline engines or the other way around. Diesel engines feature higher compression ratios and various fuel injection methods, resulting in additional heat and stress on engine elements. As a result, diesel oil is designed to give better protection against wear and tear induced by these conditions.

How often should I change 5w40 oil?

Synthetic 5W40 oil usually requires longer change intervals. This is due to the high refined materials used to manufacture the oil and the fact that it can reduce friction further compared to conventional oil.

Interval times vary based on the type of synthetic oil, the engine, the driving condition, and the manufacturer’s recommendations. However, as a general rule, 5W40 oil should be changed every 7,500 to 10,000 miles (12,000 to 16,000 Kilometers).

Consider the other related conditions such as driving too many short journeys, driving in extremely hot or cold weather, the load on the engine (heavy towing), and high-performance driving. If doing one or more of those, you may need to change the oil more frequently. Additionally, if your car has high mileage, you may need to change the synthetic engine oil more frequently to keep the engine in good condition.


Synthetic 5W40 oil quality varies greatly. If you want to have high quality, you need to get your products from a trusted engine oil manufacturer.
