Oil viscosity index (VI - Viscosity Index) is a number that allows to evaluate the change in the viscosity of a lubricating oil as the temperature changes. It is calculated using the ISO 2909: 2002 method which evaluates the kinematic viscosity of oils at 40°C and 100°C. The higher thi...
2. There are optional ways to heat the oil, like the boiler way by using fuel, natural gas or coal. Also, if machine is small capacity, we can use the electric heating way. 3. By using the high vacuum distilling way, so the distilling temperature is low, ...
4568 Oil Filter Wrench, 2 way, 3 leg • Fits filters ranging from 2-1/2" to 5-1/4" (65 mm to 135 mm) in diameter. • To turn the tool, use a 1/2" ratchet in the ratchet drive or a 13/16" wrench on the nut. • Knurled legs provide extra gripping power. Strong ...
JZC waste oil distillation machine heat the waste oil to (from 110ºC to 350ºC) different temperature under high vacuum condition, making Hydrocarbon molecules break out, and re-order combination, forming diesel oil, lubricating base oil etc. JZC machine is very suitable for the s...
The oil’s viscosity or weight is provided on the container’s label. Select the oil for your vehicle according to this chart. A very low-viscosity, fuel-efficient 0W-20 oil is the preferred engine lubricant for your Civic Hybrid. This ...
Thus tribology system calculations will then more readily involve the influence of analyses such as: combustion, heat transfer (HT) and cooling, thermal stress, distortions and lubrication (plus the effects of pump oil flow). System analysis methods described here will allow step changes in performa...
Refer to the chart at the bottom of the page for their meanings and importance. Basic Oil Knowledge Engine oil has four functions: lubrication, protection, cooling, and cleaning. In other words: performance, longevity, durability, and emissions. Engine internals are all metals: steel, aluminum,...
but I guarantee you that as the oil temperature gets hotter, like it does when sitting in traffic on asphalt on a hot summer day, the Harley-Davidson with AMSOIL in the crankcase is going to be far better protected and run far cooler than the bike with H-D "Genuine" oil in it. Ther...

The chart below shows the proper oil viscosity for VW engines under specific climatic conditions. The SAE viscosity number of the oil should be selected for the lowest anticipated temperature at which engine starting will be required, and not for the temperature at the time of the oil change. ...
