Find viscosity tables and charts for engine oil at multiple temperatures (viscosity and density values with their source).
Choosing the right motor oil viscosity is essential for protecting your engine, optimizing performance, and ensuring good fuel efficiency. Your vehicle’s owner’s manual will typically recommend a specific oil or a range of viscosities.
In the oil viscosity chart, you’ve got different viscosity grades in the middle and the corresponding kinematic viscosity and saybolt viscosity at two temperatures on the left and right, respectively.
The first indicates the oil’s viscosity at low temperatures, while the second represents its viscosity at high temperatures. These ratings are essential for determining the oil’s suitability for different operating conditions and ensuring proper lubrication and engine protection.
ENGINE OIL VISCOSITY CHART. What do oil viscosity numbers mean? Viscosity is the resistance to flow of a fluid. Motor oil viscosity grades are based on a scale developed by the API (American Petroleum Institute) lubricant organization.
Download and print Dynamic Viscosity Chart - SAE vs. temperature. Dynamic viscosities for motor oils SAE 10 to 50 for temperatures ranging 0-100 <sup>o</sup>C.
Viscosities based on 96 VI single grade oils. ISO are specified at 40°C. AGMA are specified at 40°C. SAE 75w, 80w, 85, 5w, & 10w. specified at low temperature. Equivalent viscosities for 100° & 210°F are shown. SAE 90 to 250 and 20 to 50 specified at 100°C. ISO viscosity classification system.
Most engine oils will be multi-viscosity with a low- and high-temperature grade, like 5W-30 or 10W-30. Multi-viscosity blends are usually the best choice for most applications, as the oil provides protection in multiple climates or environmental conditions.
Dive into the world of oil viscosity ratings with an insightful Oil Viscosity Chart. This tool simplifies choosing the right oil grade for your vehicle, based on its resistance to flow at different temperatures. Understand the viscosity scale developed by the API for optimal engine performance.
By John Addison / April 15, 2024. Are you confused by the numbers and letters on your engine oil bottle? Understanding engine oil viscosity grades is crucial for keeping your vehicle running smoothly. What Are Engine Oil Viscosity Grades? Engine oil viscosity refers to how easily oil pours at different temperatures.
