The term "forty weight" is commonly used in automotive jargon to refer to a specific type of engine oil with a viscosity rating of 40. In this context, "weight" is a colloquial term that denotes the thickness or viscosity of the oil.
The etymology of "forty weight" can be traced back to the Society of Automotive Engineers (SAE) viscosity grading system, which was established in the early 20th century. The SAE developed a numerical code to classify the viscosity of engine oils, ranging from low to high. As part of this classification, a two-digit number followed by the letter "W" was used to denote the viscosity rating at both cold and operating temperatures.
For instance, a 40-weight oil implies that it has a viscosity grade of 40 and performs within a certain range of viscosity at a given temperature.
