Viscosity multi-grade oils

Table 4-162 Composition, Viscosity and SAE Specification of Multi Grade Oils ... Table 4-162 Composition, Viscosity and SAE Specification of Multi Grade Oils ...
Lubricant additive, usually a high molecular-weight polymer, that reduces the tendency of an oil to change viscosity with temperature. Multi-grade oils, which provide effective lubrication over a broad temperature range, usually contain V.I. improvers. [Pg.343]

OIL, MULTI-GRADE - An oil having relative little change in viscosity over a specified temperature range. [Pg.108]

To provide a mechanism of gellation for petroleum-based greases and encapsulants. Related to this, block copolymers provide viscosity index improvement in multi-grade lubricating oils. Tri-block copolymers... [Pg.19]

Viscosity Index Improver Viscosity index improvers, which can be present in multi-grade lubricating oils, can bias measurements. However, the biases can be reduced to negligible proportion by using the specified solvent-to-sample dilution and an internal standard. [Pg.767]
