SAE 5W-30, 15W-40, 10W – what does it all Viscosity (a fluid's resistance to flow) is rated at 0° F (represented by the number preceding the "W" [for Winter]) and at 212° F (represented by the second The higher numbers of a gear oil (e.g., 75W-140) do not mean that it has higher The SAE designation for multi-grade oils includes two viscosity grades; 11 Sep 2019 Viscosity refers to the thickness or thinness of the oil. The latest engine oils are two grades. One is for lower temperature, and other is for higher. What do the viscosity numbers mean? The viscosity of an oil is measured by its resistance to flow. There are two numbers that define the viscosity of an oil. The first 20 Jul 2012 These oils have two numbers in its viscosity grade.

The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. Most oil and gas commissions make API numbers (and well header data) available on-line and free of charge. The ability to download the data varies from state to state. Below is a list of the 50 states, along with their state code, and the name and internet address of their oil and gas regulatory agency where available.
this means is that if the engine is to perform at its best, the oil must be able to retain the grades are made up of two numbers, between which is the letter W ( for.

Synthetic blend oil offers the best of both worlds. It has many of the characteristics of full synthetic oil, but at a much lower price. This type of oil is a mixture of
I receive a lot of questions regarding oil and the least understood part is the number system used to rate oils. Oil weight, or viscosity, refers to how thick or thin the oil is. The temperature requirements set for oil by the Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high).
