Evaluation of viscosity reduction effect of oil-soluble viscosity reducer on crude oil
AbstractIn this paper, several crude oil viscosity reducers were selected to evaluate their performance on the heavy oil Henan Oilfield, China. Through investigation, the viscosity reducing ability of these viscosity reducers were relatively general. Among them, EVA had the highest performance, reaching a viscosity reduction rate of 45.6%.

Effects of Oil Viscosity on Seizure
Though the effects of oil viscosity, which is an important factor for oil film formation, on the scoring resistance of gears have been examined, in the former studies the significant influences of specific sliding on the antiseizure capacities of lubricating oils were not taken into account. Thus, in this paper, as a basic study to establish the design
