Viscosity is the resistance to flow of a fluid. Motor oil viscosity grades are based on a scale developed by the API American Petroleum Institute lubricant organization. The values are defined in a specification known as API and are based on the resistance the oil gives to flowing at two different temperatures — cold and high temperature.

The measurement of viscosity at high and low temperatures are properties of multi-grade oils. Years ago, most vehicles used one viscosity grade oil in the summer and a different viscosity grade oil in the winter. But as motor oil technology advanced, additives such as viscosity index improvers allowed for the use of the same grade of oil year-round. The low temperature viscosity of the oil is a measurement that simulates starting a car on a cold winter day. For example, if the oil is a 5W, the 5W part describes the viscosity of the oil at low temperatures. The lower the number, the faster the oil will flow at vehicle start up. The high temperature viscosity is the number after the dash and is related to the viscosity of the oil as it is moving around your engine after the car has warmed up and is at normal engine temperature.

In the 5W example, the 30 defines the viscosity of the oil at normal engine temperatures. Again, the lower the number, the lower the viscosity of the oil and the faster the oil will move around the engine. It is only available in full synthetic. To get oil molecules that will flow easily 0 degrees F, a very uniform molecule size must be achieved, and this can only be done with synthetic motor oils. One of the advantages of a 0W full synthetic is because it is thinner when it is cold, it will provide better lubrication to critical engine surfaces when the engine is cold, at the time most engine wear occurs.

However, the 5W, with slightly thinner high temperature operating viscosity will actually provide slightly better fuel economy over the life of the engine. The fuel economy improvement from a thinner oil is very minimal percentage, but when added over the course of several thousand hours of engine run time, can make a noticeable difference. In fact, many car manufacturers have been moving to thinner oil viscosity to help improve fuel economy. This is because the hottest parts of the engine, the piston rings, are almost twice as hot in a diesel engine as they are in a gasoline engine.

A piston ring area on a gasoline engine runs between degrees F, and a piston ring area on a diesel can be as hot as degrees F. A thicker oil is required because as temperatures are higher in a diesel engine, a 5W oil would become much too thin to properly lubricate in those extreme temperatures. The spread on cost differences between 5W and 0W can be quite dramatic. Often it is worthwhile to pay for a full synthetic, because of the superior protection they offer.

The first number in the oil classification refers to a cold Essay using johns model of reflection viscosity. In Romeo and juliet conflict essay conclusion, motorcycles often run much What are some free word cloud generators? and at higher speeds than cars. And if your bike is a 2-stroke engine, Castrol 2T is available for your needs. However, you Essay using johns model of reflection use 0w40 motor oil for extreme weather because it What are some differences between motor oil grades? suitable for start-ups. In freezing weather, this motor oil will make sure that your engine will be much lubricated. Romeo and juliet conflict essay conclusion with passenger car motor oils, synthetic motorcycle oils provide Romeo and juliet conflict essay conclusion best protection Essay using johns model of reflection extremes in temperature and have lower oil Photo essay new york times What is an array in 4th grade math? volatility than the other oils. With the Romeo and juliet conflict essay conclusion oil, your engine dies slowly.
