Weight, in this sense, is the viscosity – or thickness – of the oil. Most oils sold at your local parts store will be multi-weight (having more than one viscosity). Oil The following is a breakdown of motor oil basics. VISCOSITY AND OIL WEIGHTS Viscosity is a fluid's resistance to flow. A higher viscosity fluid like honey takes Gear Oil Weight Explained. by James T Wood. Gear oil is used as a lubricant between the moving parts of a gear system so that the gears mesh and turn 29 Jan 2018 This W with a number before it refers to the cold weather viscosity of the oil. This first number represents the oil's resistance to flow at 0 deg F.
The first number in the oil weight represents the oil's viscosity at 0 degrees F. The lower the first number in an oil's weight, the thinner it is at low temperatures. Oil that is thinner at cold temperatures is typically better suited for winter driving. Multi-weight oils (such as 10W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature. Liquids such as fixed oils and essential oils are sometimes measured by weight. Some dry goods, such as salts, sugars and herbs, are measured by volume such as 1 cup (8 fluid ounces). One Fluid Ounce of an Ingredient is Not Equivalent to One Net Weight Ounce of the Same Ingredient Your car's owner's manual will list the recommended oil weight, whether that's a standard like 10W-30 or something more unusual. Later on, we'll explain what that weight means and how you should
Heavy oils contain a greater percentage of the higher-molecular-weight petroleum hydrocarbons that are more resistant to weathering. Solubility in water is the These are ISO Viscosity Grades, American Gear Manufacturers Association ( AGMA) grades, SAE crankcase oil grades and SAE gear oil grades. Listed below

Oil weight is a term used to describe the viscosity of an oil, which means how well it flows at a specific temperature. 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. Viscosity is the most important property of a lubricant. Understanding viscosity promotes the ability to reduce wear, improve fuel economy, and make more horsepower. For starters, in oil nomenclature, “W” does not stand for “Weight”. It stands for “Winter” and that is the key to understanding viscosity grades. The first number in the oil weight represents the oil's viscosity at 0 degrees F. The lower the first number in an oil's weight, the thinner it is at low temperatures. Oil that is thinner at cold temperatures is typically better suited for winter driving. Multi-weight oils (such as 10W-30) are a new invention made possible by adding polymers to oil.
