What engines use 5w20 oil grade?

The 5W20 is specially designed for use in these very modern engines. These engines are designed to use thinner oils that reduce friction and improve fuel efficiency. 5W20 is ideal for this because it has a high, stable viscosity.

The properties of 5W20 also allow it to lubricate critical engine parts during startup where thicker oils would not be able to reach these areas due to their high viscosity.

This means that there is less wear on moving parts during cold starts. In addition, as the engine reaches operating temperature, the oil becomes more viscous (thicker) and provides full protection for the engine throughout its lifespan.

The 5W20 can also be used in older engines. However, they weren’t designed to have very low oil viscosity, so it is a good idea to switch to a thicker oil when a machine gets older.

5W20 is also very good for use in high-performance and racing engines. However, some of the properties that make 5W20 so great for everyday driving can be detrimental to a high-performance engine.

It is also ideal for older cars with a significant temperature difference between summertime running and winter startup procedures.

5w20 Buying Guide

5w20 is one of the most common oil specifications. It specifies an engine oil viscosity that may be appropriate for several driving conditions and climates, taking into account temperature ranges for the startup, average operating temperature, maximum operating temperature, and minimum acceptable temperature. It is typically thicker than a 5w30 grade while not being as wide as a straight 30 grade.

Look at the specification: The viscosity of a 5w20 oil will be designated as SAE 5w20. This is the viscosity grade and should be used as a general guideline for viscosity within the 5w20 oil category. ​

Do your research: A 5w20 oil will not have the same characteristics as a 20-grade straight weight oil, for example. So ensure you are selecting exactly what you need! A lower quality product will likely be less expensive but may provide less viscosity, leaving your car at risk for overheating.

Look at the oil container: An engine oil container must display an API (American Petroleum Institute) service symbol, also known as a “donut.” For example, Chevron™ uses a white donut with black lettering. The five lines inside the donut indicate that it meets the requirements of API Service SJ. There are other variations to SAE 5w20, such as SJ, SL, or SM. The API “donut” is the only way of knowing precisely what you are buying.

Check your vehicle manual: Your vehicle owner’s manual will list the type of oil recommended for your specific vehicle model. Use this information when comparing different kinds of oil.


Your car is going to depend on a number of factors. First, you need to consider the climate in which you drive most often and choose an appropriate oil for this type of environment.

You may also want to make sure that the vehicle manufacturer recommends or approves one of these types of motor oils before purchasing it. especially if there’s any chance that you will be driving off-road at all while using this product. Finally, take into personal consideration preferences such as price point and viscosity when making your decision on what kind of oil to buy next time! So I hope this post is helpful for you. If you have any questions about the 5w20 grade please feel free to ask me in the comment box. Thank you!
