It is intended as a targeted treatment to address friction-related noises and erratic cylinder motion; it is not a universal hydraulic fluid and must be used according to Caterpillar equipment recommendations. One bottle treats a hydraulic reservoir as directed by service instructions and should not be added to systems that share a common sump for hydraulics, brakes, and transmissions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this additive address stick-slip and cylinder chatter?\u003c\/h3\u003e\n\u003cp\u003eThe formulation lowers friction at mating surfaces inside hydraulic components, helping cylinders move more consistently and reducing the sudden motion that causes chatter. It conditions the oil film and helps maintain smoother contact between seals, pistons, and bores without altering base fluid specifications when used as directed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces intermittent sticking that causes jerky cylinder motion.\u003c\/li\u003e\n  \u003cli\u003eConditions surfaces to promote a steadier lubricating film.\u003c\/li\u003e\n  \u003cli\u003eEngineered for compatibility with approved Cat hydraulic fluids.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this additive reduce overall hydraulic system noise?\u003c\/h3\u003e\n\u003cp\u003eWhen used in applicable systems, the additive can noticeably lower operational noise by minimizing friction-caused vibration and chatter.
