The Society of Automotive Engineers (SAE) have established a numerical code for grading motor oils according to their viscosity from low to high. Single grade oils are designated 5, 10, 15, 20 and so on. Multigrade oils are designated 10-50 for example and must pass the grade requirement for both 10 and 50. Multigrade oils are designed to operate over a wide range of temperatures, from freezing conditions to temperatures created by hot operating engines
the higher the SAE number, the thicker the oil and higher the viscosity of the oil.
SAE 40 has a higher viscosity.
SAE 40 has a higher viscosity.
The ISO viscosity grade of Shell Tellus 37 is 32 and its SAE viscosity grade is 10W. These viscosity grades indicate the fluid's viscosity characteristics at different temperatures and operating conditions.
SAE ratings on motor oil have to do with the viscosity of the oil. The viscosity is the oil's resistance to flow, or an oil's speed of flow as measured through a device known as a viscometer. The higher the SAE, the thicker the oil and the slower it will flow. Oils that have a number like 5W30 or 10W30 have been tested at a colder temperature. These oils will flow at the fist number's rate at colder temperatures and the second number's rate at higher temperatures. SAE means Society of Automotive Engineers

SAE-40 oil refers to oil that meets the Society of Automotive Engineers (SAE) specification for viscosity grade 40. The "SAE" indicates the standards set by the organization, while the "40" denotes the oil's viscosity at high temperatures. This type of oil is typically used in engines requiring higher viscosity for optimal performance, especially in warmer climates.
SAE stands for Society of Automotive Engineers. Sae ratings pertain to the oils Viscosity. Viscosity is the flowability (resistance to flow) at a particular temperature.
SAE 10W30
A motor oil with a high viscosity (resistance to flow) like SAE 50, will be your greatest density motor oil. Low viscosity like SAE 20 will have the least density.
Yes, SAE 30 oil is thicker than SAE 10 oil. The numbers in the SAE (Society of Automotive Engineers) rating indicate the oil's viscosity, with higher numbers representing thicker oils. Therefore, SAE 30 has a higher viscosity than SAE 10, making it more suitable for higher temperature applications or older engines that require thicker oil for better lubrication.
