CAT Hydraulic Oil Additive — 1 Quart Low-Friction Formula for Noise Reduction & Stick-Slip Control

This genuine Caterpillar additive was developed and tested for use in select hydraulic systems to improve component interaction and operator comfort. 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.

How does this additive address stick-slip and cylinder chatter?

The 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.

• Reduces intermittent sticking that causes jerky cylinder motion.
• Conditions surfaces to promote a steadier lubricating film.
• Engineered for compatibility with approved Cat hydraulic fluids.

Will this additive reduce overall hydraulic system noise?

When used in applicable systems, the additive can noticeably lower operational noise by minimizing friction-caused vibration and chatter. It improves operator comfort and machine quietness but is not a cure-all for noise from mechanical wear or misalignment.

• Targets friction-related noise sources in hydraulic circuits.
• Helps achieve smoother, quieter cylinder travel under load.
• Works best alongside routine maintenance and correct system setup.

Is this product compatible with my Caterpillar machine?

This is a Genuine CAT additive intended for use in specific Caterpillar hydraulic systems; compatibility depends on the machine model and whether the system shares fluid with brakes or transmissions. Always consult your Caterpillar service manual or dealer before adding the product to a system.

• Approved for select Cat hydraulic applications only.
• Do not use in systems with a common sump for hydraulics, brakes, and transmissions.
• Follow Caterpillar service guidelines for dilution ratios and service intervals.

How do I apply the 1-quart bottle and what can I expect?

Application instructions and recommended dosages are provided by Caterpillar for specific reservoir sizes; typically the bottle is added to the hydraulic fluid and allowed to circulate under normal operation. Expect improved smoothness and reduced chatter over time, though results vary with system condition and severity of the issue.

• Single 1-quart bottle packaged for straightforward addition to the reservoir.
• Allow system to run so the additive blends and conditions components.
• Monitor performance and consult dealer if noise persists or worsens.

Who is this for? This additive is for owners, operators, and service technicians of Caterpillar equipment who need a manufacturer-developed solution to friction-related hydraulic noise and stick-slip behavior in approved systems. It is ideal for machines specified by Caterpillar to accept this treatment and for fleets that prioritize Genuine CAT parts and service procedures. Do not use it in machines with shared fluid sumps or where the equipment manual advises against additives; when in doubt, contact your Cat dealer for application guidance.
