Why the Saturn V Used Kerosene for its Hydraulics Fluid
https://hackaday.com/2024/11/11/why-the-saturn-v-used-kerosene-for-its-hydraulics-fluid/

Gimbal systems proposed for the F-1, oxygen-kerosene engine. The fueldraulic system (left) is simpler, with fewer components than the high-pressure hydraulic system. To simplify the illustration, flexible fittings and hose, and lines to other gimballing actuators and to other fluid power systems on the S-IC stage are not shown.
