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 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.
Viscosity SAE 5W-30 V6 Engines Viscosity SAE 5W-20 V8 Engines
The SAE rating, established by the Society of Automotive Engineers, indicates the viscosity of engine oils. It is represented by a number followed by a "W" (for winter) and another number, such as 5W-30. The first number denotes the oil's viscosity at low temperatures, while the second indicates its viscosity at higher temperatures. This rating helps consumers choose the appropriate oil for their vehicle’s operating conditions.
