Patent ID: 8022024

Claim:
A shock absorber fluid, comprising: a. a base oil, that is not an oil based on PAO, having consecutive numbers of carbon atoms, a kinematic viscosity at 100° C. between 1.5 and 3.5 mm 2 /s, a pour point less than −35° C., from greater than 5.8 wt % up to 27.5 wt % total molecules with cycloparaffinic functionality, and less than 10 wt % naphthenic carbon; b. additives; and c. less than 3.0 wt % pour point depressant, based on the total shock absorber fluid; wherein the shock absorber fluid has an air release after 1 minute by DIN 51381 of less than 0.8 vol %; and wherein the shock absorber fluid is made without any viscosity index improver and has a viscosity index greater than or equal to 129.
