| 摘要 |
A composition made by admixing a major amount of base oils of lubricating viscosity and minor amounts of additives. The additives can include a viscosity modifier, a dispersant, a friction modifier, an anti-oxidant, a suppressant, a tackifier, and thickeners. The dispersant can be a dissolved powered styrene-ethylene/propylene-block copolymer and the thickeners can be fumed silicia. The dispersants and the thickeners are pulverized and dissolved in the composition to provide for inhibition of oil separation during storage. |
