What is the viscosity of an engine oil?
What is the viscosity of an engine oil?
Viscosity of Engine Oil. Description. Engine oils are generally formulated oils. They consist of mineral, semi- or fully synthetic base oil (base stocks) plus a varying number and amount of additives. The quality of an engine oil depends on the base stock and its properties as well as on the additives.
How does temperature affect the flow of engine oil?
Temperature impacts the flow properties of engine oil. Engine oil is available in different SAE grades to suit the climate where it is used and the purpose of the user. Dyn. Viscosity [mPa.s] Kin. Viscosity [mm²/s] Dyn. Viscosity [mPa.s] Kin. Viscosity [mm²/s] Dyn. Viscosity [mPa.s] Kin. Viscosity [mm²/s] Dyn. Viscosity [mPa.s] Kin.
How is viscosity measured on a cold crank test?
Dynamic viscosity is measured using the Cold Crank Simulator test, and is used to determine an oil’s low-temperature viscosity grade. This would be the “5W” in Amsoil XL 5W-30 Synthetic Motor Oil.
What is the viscosity index of AMSOIL 5W-30?
This would be the “5W” in Amsoil XL 5W-30 Synthetic Motor Oil. Additionally, you should be aware of what exactly the viscosity index (VI) is. The viscosity index refers to how much the viscosity of a lubricant changes due to fluctuations in temperature. An oil’s VI is measured at 40°C and 100°C.

Can a straight weight oil be used in a multi viscosity system?
Straight weight oil is never recommended for use in a system that requires a multi-viscosity oil. Straight weight oils are generally recommended for smaller engines or older vehicles that were made before multi-viscosity oils were produced. Is switching types of motor oil (conventional, synthetic, etc.) harmful to my vehicle’s engine?
How does oil viscosity affect the oil pump?
Higher or heavier viscosity oil drives up the oil pressure which in turn makes the oil pump work against a higher resistance. In this vein of thought, the oil pump is ultimately just another horsepower robbing accessory similar to the alternator or water pump.
