Advantages
of Zinc-free
Hydraulic Oils
Zinc-based hydraulic
oils have historically
performed well. If no
underlying reason exists
for utilizing a zinc-free oil,
such as the metallurgy
of a component or the
environmental/operating
factors, then there is a
strong case to use zinc-
based additives. Check
out this article on the ML
site to discover when the
benefits of zinc-based
additives outweigh the
risks as well as some of
their disadvantages.
What You Should Know
About Oil Filters
Although beta ratios and micron ratings
are typically the first considerations when
evaluating an oil filter, perhaps the most
crucial attribute of any filter is its dirt-
holding capacity. Access this 1-minute,
34-second video to learn which types of
filters can hold more dirt and why this is
important, as well as how you can quickly
determine the dirt-holding capacity of your
oil filter.
Determining an Oil's
Energy Efficiency
Energy efficiency must be measured in
terms of the reduction of energy consump-
tion. More specifically, it is related to how
much energy the machine consumes in
order to operate. Understand how this
principle applies to machines that convert
one type of energy like chemical or electric
to a mechanical one, such as electric
motors and combustion engines, by reading
this article on the ML site.
Advice for Proper
Lubricant Storage
Contaminants and extreme temperatures
can severely affect the life and performance
of your lubricants. Access this 1-minute,
53-second video to hear about the
importance of storing lubricants indoors
and away from any type of contamination
as well as some of the best methods for
keeping lubricants clean, cool and dry.
How a High Base Number
Can Affect Engine Oil
The higher an oil's base number, the higher
its ash content and the greater its ability
to prevent acid corrosion in the engine.
However, the mandatory use of ultra-low-
sulfur diesel fuel on highways has reduced
the need for higher base number additive
content. Read this article on the ML site to
find out why you should consider switching
to an engine oil with a lower base number.
