How To Read Oil Weight. To read the grade of engine oil, look at the sae (society of automotive engineers) classification. The society of automotive engineers (sae) assigns a viscosity number, or weight, to oil based on its flow at 210 degrees f, which is roughly the standard operating temperature for most motors.

Web the low temperature viscosity of the oil is a measurement that simulates starting a car on a cold winter day. Web to read oil weight, first identify the oil’s grade on the american petroleum institute (api) scale. A downloadable motor oil guide shelf card is available in pdf format. To read the grade of engine oil, look at the sae (society of automotive engineers) classification. Web look up “oil” in the index, or check the reference section in the back of the manual. The society of automotive engineers (sae) assigns a viscosity number, or weight, to oil based on its flow at 210 degrees f, which is roughly the standard operating temperature for most motors. Depending on the based oil used in the formulation, there are different viscosity values and differences between temperature properties, stability, and oil consumption. Sometimes there will be a choice of oils, based on different climate conditions. This will be a number between 0 and 100. It's a measure of viscosity, or the thickness of a fluid.
The higher the vi, the lighter the oil. Web oil weight is a term used to describe the viscosity of an oil, which means how well it flows at a specific temperature. This will be a number between 0 and 100. A downloadable motor oil guide shelf card is available in pdf format. These are known as multigrade oils. To read the grade of engine oil, look at the sae (society of automotive engineers) classification. Web look up “oil” in the index, or check the reference section in the back of the manual. Next, find the viscosity index (vi) of the oil. That value has the letter “w” after the number and has a dash after the w. Web the low temperature viscosity of the oil is a measurement that simulates starting a car on a cold winter day. Sometimes there will be a choice of oils, based on different climate conditions.
