It flows better in cold conditions.
Low viscosity oil flows easier when it is cold but become thinner when it is hot.
The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscositycharacteristics. SAE viscosity gradings include the following, from low to high viscosity: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. The numbers 0, 5, 10, 15 and 25 are suffixed with the letter W, designating they are "winter" or cold-start viscosity, at lower temperature.
A motor oil with a high viscosity (resistance to flow) like SAE 50, will be your greatest density motor oil. Low viscosity like SAE 20 will have the least density.
Very low freezing point (you can leave your spirit level outdoors in winter even in Finland)Low viscosity (the bubble moves freely and the same whether warm or cold)
Yes, it does have low viscosity.
Low Viscosity was born in 1995.
Some cheaper oil can loose viscosity at low temperatures.
For a material with low viscosity the flowing is easier.
The viscosity is similar to the viscosity of water.
honey has high viscosity lah, and water has low viscosity. anything that resists flow has high viscosity...lah. honey has high viscosity lah, and water has low viscosity. anything that resists flow has high viscosity...lah.
Yes, 10W30 motor oil is thicker than 5W30 motor oil at higher temperatures. The first number in the oil designation (the "W" stands for winter) indicates the oil's viscosity at low temperatures, meaning 5W30 is thinner in colder conditions compared to 10W30. However, both oils have the same viscosity at operating temperatures (30), meaning they perform similarly once the engine is warmed up.
Neither. Each has it's purpose. Use exactly what the manufacture recommends and use a multi-viscosity oil that will work in both cold and hot climates. The most common weight recommended in in new cars today is SAE 5w20.
