发明名称 PROCESSO PARA PRODUZIR UM FLUIDO ABSORVEDOR DE CHOQUE
摘要 A process to make a shock absorber fluid having improved performance properties, the properties including an air release after 1 minute by DIN 51381 of less than 0.8 vol %, a kinematic viscosity at 100° C. less than 5 mm2/s and an aniline point greater than or equal to 95° C., or meeting the specifications for Kayaba 0304-050-0002 or VW TL 731 class A. The shock absorber fluid is made by blending a base oil having less than 10 wt % naphthenic carbon and a high viscosity index with low levels of (or no) viscosity index improver and pour point depressant.
