Cat HYDO vs. Industrial Hydraulic Oils

Typical industrial hydraulic oils separate water and oil, which can cause valve sticking or excessive wear on your hydraulic system. Cat HYDO disperses small amounts of water throughout the oil to ensure proper lubrication. Cat HYDO is formulated to hold and disperse water so that it does not harm mobile hydraulic systems. Industrial hydraulic oils—often described as Anti-Wear—do not contain emulsifiers and are specifically designed to separate water as shown below. Separated water drawn through the system can damage pumps and other components. If this water freezes, it can cause even more serious damage. Avoid oils whose specifications indicate that they "separate " "shed" or "release" water.

* The values shown are typical values and should not be used as quality control parameters to either accept or reject product. Specifications are subject to change without notice.

** New oil, as received, with 0.1 % water by volume added.

To minimize the number of oils on your job site, the following oils can be used as direct replacements for Cat HYDO:

DEO™ 15W-40 tdTO™ 10W
MTO tdTO-TMS™

For startups in extremely cold temperatures down to -30°C (-22°F), consider using Cat DEO SYN™ 5W-40. This is a full synthetic diesel engine oil.

S•O•S^SM Services for early problem detection

Protect your investment with Cat S•O•S oil analysis, the ultimate detection and diagnostic tool for your equipment. S•O•S helps you detect potential problems before they can lead to major failures and costly, unscheduled downtime.

Cat Filters: Complete protection for your machine

Combine Cat Fluids with Cat Filters for the highest level of contamination control and protection foryour machine. We recommend Cat Filters for all Cat machine applications.
