has introduced three new premium hydraulic oils. Clarity Synthetic Hydraulic
Oil AW, Rando HDZ and Rando HD Premium Oil MV offer multi viscosity or high
viscosity index (VI) formulations that Chevron says deliver fuel cost savings
and increases in productivity when compared to conventional monogrades.
The new premium hydraulic oils feature improved oxidation
and shear stability — versus conventional monogrades — which deliver robust
protection to hydraulic pumps, Chevron says.
Clarity Synthetic Hydraulic Oil AW (ISO 32, 46, 68), which
provides excellent performance in low temperature climate, is designed to give
maximum protection to both mobile and stationary vane-, piston-, and gear-type
hydraulic pumps in high-performance applications as well as in environmentally
sensitive areas, Chevron says.
The oil has a high viscosity index to improve hydraulic
response time and increase operating temperature range, Chevron says. In field
trials, Clarity Synthetic Hydraulic Oil AW has proven to reduce fuel
consumption by improving overall hydraulic pump efficiency by up to 8 percent.
By improving pump efficiency, it also showed a potential gain of 5-25 percent
increased productivity depending on usage environment, Chevron says.
Rando HDZ oils (ISO 15, 22, 32, 46, 68, 100), are antiwear
hydraulic oils formulated with premium base oil technology to protect hydraulic
pumps against wear, rust and corrosion, Chevron says. They are recommended for
hydraulic or circulating oil systems, including marine on-deck machinery,
hydraulic actuated loading bins, or equipment that require a wider operating
temperature as compared to a single viscosity grade oil.
In laboratory efficiency testing, Chevron says, Rando HDZ
oils provided up to 5 percent improvement in overall hydraulic pump efficiency
when compared to a typical monograde hydraulic oil like Hydraulic Oil AW (a
lower VI product with VI<105). The multiviscosity feature of Rando HD
Premium Oil MV promotes even and continuous power transmission over a wide
temperature range with a minimum of shudder.
“In today’s highly competitive markets, companies are
looking at all opportunities to improve efficiency, and therefore the bottom
line,” said Jeff Snyder, Industrial Brand Specialist, Chevron Lubricants in a
Chevron press release. “Hydraulic performance is often overlooked in this
quest, but the right hydraulic fluid can deliver impressive fuel economy and
hydraulic system performance improvements. The improved efficiencies reduced
fuel consumption and lowered lubricant purchase volumes of Chevron’s premium
products provide additional benefits to our customers compared to conventional
hydraulic fuels. ”
