Motor oil weight explained

The measure of the thickness of a liquid is called viscosity. The term viscosity refers to the thickness of the oil and its resistance to flow.

The temperature requirements set for oil by the Society of Automotive Engineers SAE is 0 degrees F low and 210 degrees F high.

Motor oil weight explained. Motor Oil Viscosity Index Usually choosing the ideal motor oil weight is a compromise. If the weight or viscosity is too low the oil will grow too thin and wear will appear on the metal surfaces of a machine. If it is too high the machine will struggle to pump the oil resulting in loss of energy.

Explain Motor Oil Weights First Number. The first number in the oil weight represents the oils viscosity at 0 degrees F. The lower the first.

The second number the number after the W represents oils viscosity at 212 degrees F. Manufacturers recommend the. How to know what motor oil weight to use in your car If this sounds complicated dont fret.

Theres an easy way to pick the right oil to put into your vehicle. Check your owners manual. Look up oil in the index or check the reference section in the back of the manual.

Is it ok to switch motor oil weights for example from a 5W-20 to a 10W-30. Some vehicle manufacturers provide a range of recommended motor oil viscosity grades based on the outside temperature in which the car is driven. Other manufacturers recommend the use of only one motor oil viscosity grade.

Consequently if the motor oil performs like a SAE 20 motor oil at the reduced temperatures the scale varies - see the chart then it will be a SAE 20W motor oil. If a motor oil passes the cold temperature or W winter grade specification for a SAE 15W and at 210 F 100 C flows through the viscometer like a SAE 40 motor oil then the. Motor oil engine oil or engine lubricant is any one of various substances that consist of base oils enhanced with various additives particularly antiwear additives detergents dispersants and for multi-grade oils viscosity index improversMotor oil is used for lubrication of internal combustion enginesThe main function of motor oil is to reduce friction and wear on moving parts and to.

The owners manual for your car will list its recommended oil weight whether thats a standard format like 10W-30 or something more unusual. That number refers to the viscosity or thickness of. Motor Oil Grades 0W-20 This engine oil is relatively thinner when you start the engine.

Here in 0W-20 the viscosity of the oil is 0 when. 0W-30 The 0W-30 oil is engineered to behave as a 0 weight oil at the starting temperature and a 30 weight oil when the. 0W-40 The 0W-40 oil is engineered to.

Oil weight doesnt refer to how heavy an oil is. Its a measure of viscosity or the thickness of a fluid. Syrup for example has a high viscosity while water has a low viscosity.

Gear Oil Weight Explained Viscosity. The measure of the thickness of a liquid is called viscosity. Though there are several different measurements.

Viscosity is affected by temperature. SAE viscosity ratings are given for the oil as measured at 212. The SAE grading system.

To be blunt about the subject if a bottle of oil does not contain the following basic information then DO NOT buy it. Look for something that does. 1 The purpose for which it is intended ie.

Motor oil Gear oil etc 2 The viscosity ie. 10w40 5w30 etc for Motor oils and 80w90 75w90 etc for Gear oils. Finally motor oil cleans acids and silicon oxide from engine parts.

An important factor in all these functions of motor oil is the oil viscosity. Read on to have oil viscosity explained in simple terms. The term viscosity refers to the thickness of the oil and its resistance to flow.

Motor Oil Basics of Viscosity Weights Explained By bimmertips January 29 2018 Fun Facts oil viscosity weight The topic of oil is very complex and can go into many different topics such as viscosity conventional synthetic blends additivesthe list goes on. 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. Synthetic motor oil is the pinnacle of engine lubrication for high-performance vehicles. Despite the name though synthetic oil is still derived from the thick black stuff ejected by oil wells.

The difference is that its molecular structure and properties are modified refined and synthesised using complex laboratory processes. The oil weight is its viscosity index at 100 degrees C the boiling point of water. Low viscosity motor oils that pour easily at low temperatures typically have a 0W 5W or 10W rating.

There are also 15W- and 20W-grade multi-weight motor 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.
