Abstract (en)

[origin: WO2020123438A1] The instant disclosure generally relates to lubricating compositions having an oil of lubricating viscosity and a mixed dispersant additive package. The mixed dispersant additive package can include an acylated poly(1-olefin)-based dispersant and a polyisobutylene succinimide dispersant where the ratio of the acylated poly(1-olefin)-based dispersant to the polyisobutylene succinimide dispersant in the lubricating composition is from 3:1 to 1: 3.
