![]() Oil Viscosity Converter Convert between commonly used oil. ![]() Theres a wide range of SAE oil available in the market. Read-across viscosity grades must contain an equal amount of the same Group V base stock (e.g., ester) in the finished oil blend if a Group. Example SAE 10W-40 where 10W refers to low-temperature - or winter - viscosity and 40 refers to the high-temperature - or summer - viscosity. Lube oils can be multigrade or monograde where multigrade oils fulfills two viscosity specifications. Oil Flow Pressure drop in oil pipes - viscosities ranging 100 - 600 Saybolt Universal Seconds. The SAE viscosity grade is not the actual viscosity value of the motor oil. Viscosity of lube oil is determined by the Society of Automotive Engineers (SAE). Oil Lubrication - Temperature Limits Temperature limits for lubricating oils. Learning more about your specific application can help deliver extra value and performance, while avoiding unnecessary expenses. Dynamic viscosities for motor oils SAE 10 to 50 for temperatures ranging 0-100 o C. We'd recommend looking also at oils by category (such as Spindle, Way, Gear, and Hydraulic oils) and consider between synthetic and conventional oils. Translating the viscosity is a good first step and can be sufficient for most general-purpose applications. This is a good approximation for most oils, but will lead to a small error when converting between ISO/AGMA and SAE for high Viscosity Index oils. The chart assumes the oil has a Viscosity Index of 95. ![]() with (mm /s) at (mm2/s) at 150☌ and mPa.s. Their viscosity grade is low, meaning they are particularly fluid lubricants. Oil gets thinner according to its Viscosity Index, and the chart is calculated with a specific Viscosity Index (VI 95 default) Table 1: Engine oil viscosity classification SAE J300 revised May 2004 SAE viscosity Low- Low-temperature Low-shear-rate Low-shear-rate High-shear-rate grade temperature (☌) pumping kinematic kinematic viscosity (☌) cranking 4viscosit圓 viscosity viscosity5 (mPa.s) at 22 viscosity, mPa.s max. These are SAE 0W, 5W, 10W, 15W, 20W, and 25W engine oils. 40, says that in summer, the same oil behaves like a legacy SAE 40 monograde: it has KV100 in the range. ISO VG measures oil at 40✬ and a given range to +/-10% of their stated value, so ISO VG 100 oil will have a viscosity between 90 and 100 cSt at 40✬.ĪGMA has redefined its grades to align with ISO standards, so they line up exactly. Oils grades that are on the same horizontal line (with the correct Viscosity Index) on the chart are equivalent. Several organizations (ISO, SAE, AGMA) have created competing standards to define oil viscosity ranges, but most of them mean the same thing.
