What is viscosity and how does it affect motor oil?
Viscosity, or the viscosity grade of motor oil, is a critical characteristic affecting its performance, oil viscosities, and lubrication properties. It refers to the thickness or flow resistance of a fluid, such as motor oil. Understanding viscosity is essential when comparing different motor oil grades, such as 0w-30 and 0w-20.
Motor oil viscosity changes with temperature. It thickens (higher viscosity) and becomes more viscous in colder temperatures, while it thins (lower viscosity) and becomes less viscous in hotter temperatures. The ability of motor oil to maintain its optimal viscosity across a wide range of temperatures directly impacts its ability to protect and lubricate engine components effectively.
The Society of Automotive Engineers (SAE) measures viscosity using two different methods: kinematic viscosity and dynamic viscosity. Kinematic viscosity measures the oil’s resistance to flow at normal operating temperatures, providing insights into its performance under typical driving conditions. Dynamic viscosity, on the other hand, measures the oil’s resistance to flow at cold temperatures, which is crucial for reliable engine startup and protection in colder climates.
Motor oil with the right viscosity, whether thinner oil for cold start or thicker oil for high mileage engines, ensures that engine components are adequately lubricated, reducing friction and engine wear. It also helps maintain a proper oil film thickness, preventing metal-to-metal contact and subsequent engine damage.
Next, we’ll delve into the specific benefits and considerations of 0w-30 and 0w-20 motor oils to understand how viscosity affects their performance in different conditions.

Differences in Engine Protection between 0w-30 and 0w-20
When it comes to engine protection, both 0w-30 and 0w-20 synthetic oils offer adequate safeguards, including viscosity oil management for modern engines. However, a comparison conducted by Subaru Japan suggests that 0w-30, with its higher viscosity, provides superior high temperature engine protection compared to 0w-20, making it suitable for heavy duty applications. This means that 0w-30 motor oil is more effective in lubricating and dissipating heat under extreme conditions, reducing the risk of engine damage.
To illustrate this point, let’s consider the properties of 0w-30 motor oil. With its lower viscosity at high temperatures, 0w-30 offers improved flow and coverage, ensuring all engine components receive sufficient lubrication when operating under challenging conditions. Additionally, 0w-30 motor oil has been formulated to provide enhanced protection against wear, friction, and deposits.
“0w-30 motor oil provides excellent engine protection, particularly in high-temperature environments. Its advanced formula ensures that vital engine components receive optimal lubrication, reducing the risk of premature wear and damage.”
On the other hand, while 0w-20 motor oil also provides reliable engine protection, the Subaru Japan comparison rates its high temperature protection as slightly lower than that of 0w-30. This indicates that 0w-20 may not offer the same level of lubrication and heat dissipation as 0w-30 under extreme conditions.
It is crucial to understand the specific requirements of your vehicle and consult your manufacturer’s recommendations to determine which motor oil viscosity is best suited for your engine’s needs. Choosing the right oil grade will ensure optimal engine protection, prolonging the lifespan of your vehicle and preventing costly repairs in the long run.
