Performance in Industry Test Results
ASTM D 2983 Cold Temperature Startup
In ASTM D 2983, Castrol Dual Range HV exhibited better cold temperature performance than an ISO 32 and
ISO 46 fluid. Castrol Dual Range HV flows even in colder temperatures, allowing it to reach critical
components before hazardous startup wear can occur.
Load-carrying Ability
Castrol Dual Range HV is recommended for heavily loaded applications like hydrostatic transmissions and
high speed/high pressure hydraulic circuits. It surpasses the load-carrying ability of economy and premium-
performing hydraulic fluids.

Leak Detection
Castrol Dual Range HV is dyed to facilitate leak detection.
ermal Stability
Cincinnati Milacron ermal Stability
Castrol Dual Range HV far exceeds the acceptable limits for sludge in the Cincinnati Milacron ermal
Stability test. Castrol took the thermal stability test one step further. Even aer being run through 3 vigorous
industry tests, Castrol Dual Range HV still far exceeded sludge limits, proving its use for severe service
applications.
