Lubrizol® 6776A Premium Hydraulic Oil Additive
A New Way to Prevent Varnish Buildup
Lubrizol® 6776A is designed to meet all of the traditional hydraulic oil requirements but also add a new benefit: It keeps hydraulic systems clean. A formulation containing 1.4 wt.% Lubrizol 6776A in Group I base oils was tested in an extended Eaton Vickers 35VQ-25 pump test that was allowed to run for 1000 hours. The result was a clean reservoir and clean system components.

P-69, P-70
- DIN 51524-2
- Meets wear requirements for Eaton Vickers 35VQ-25.
Traditional vs Clean
Lubrizol conducted extended Eaton Vickers 35VQ-25 pump tests. These tests were run under normal conditions except the test duration was extended to 1000 hours. Time after time traditional fluid technology showed the formation of varnish in the system reservoir and hydraulic components after only 500 hours of use.
Benefits of Lubrizol 6776A
- Excellent oxidation life, helping to extend life of oil and prevent varnish formation
- High level of thermal stability, which helps minimize the formation of varnish
- Excellent demulsibility, so water separates quickly
- Outstanding antiwear system to protect system components
- High level of rust and corrosion protection, extending component life
- Excellent filterability
