the higher the SAE number, the thicker the oil and higher the viscosity of the oil.
SAE 40 has a higher viscosity.

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
ISO = 37 SAE Engine Oil = 15W SAE Gear Oil = 75W
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.
Viscosity SAE 5W-30 V6 Engines Viscosity SAE 5W-20 V8 Engines
SAE 10w30.
SAE 10w30
sae document j300 defines the highest single grade as 60. this is in reference to viscosity and not the quality of the oil
