General Information
1-12
Always use oil with a classification
recommended by the manufacturer,
using an oil with a different classification
can cause engine damage. Viscosity is
an indication of the oil’s thickness. Thin
oils have a lower number while thick oil
has a higher number. Engine oils fall
into the 5-to50-weight range for single-
grade oils. Most manufacturers
recommend multi-grade oil. These oils
perform efficiently across a wide range
of operating conditions. Multi-grade oils
are identified by a W after the first
number, which indicates the low-
temperature viscosity. Engine oils are
most commonly mineral (petroleum)
based, but synthetic and semi-synthetic
types are used more frequently. When
selecting engine oil, follow the
manufacturer’s recommendation for
type, classification and viscosity.
Greases
Grease is lubricating oil with thickening
agents added to it. The National
Lubricating Grease Institute (NLGI)
grades grease. Grades range from
No.000 to No.6, with No.6 being the
thickest. The most typical multipurpose
grease is NLGI No.2. For specific
applications, manufacturers may
recommend water-resistant type grease
or one with an additive such as
molybdenum disulfide (MoS2).
Brake Fluid
Brake fluid is the hydraulic fluid used to
transmit hydraulic pressure (force) to the
wheel brakes. Brake fluid is classified by
the Department of Transportation
(DOT). Current designations for brake
fluid are DOT 3, DOT 4 and DOT 5, this
classification appears on the fluid
container. Each type of brake fluid has
its own definite characteristics. Do not
mix different types of brake fluid as this
may cause brake system failure. DOT 5
brake fluid is silicone based. DOT 5 is
not compatible with other brake fluids
may cause brake system failure. When
adding brake fluid, only use the fluid
recommended by the manufacturer.
Brake fluid will damage any plastic,
painted or plated surfaces it contacts.
Use extreme care when working with
brake fluid and remove any spills
immediately with soap and water.
Hydraulic brake systems require clean
and moisture free brake fluid. Never
reuse brake fluid. Keep containers and
reservoirs properly sealed.
Warning
Never put mineral based petroleum
oil into the brake system. Mineral oil
causes rubber parts in the system to
break down which could cause
complete brake failure.
Coolant
Coolant is a mixture of water and
antifreeze used to dissipate engine heat.
Ethylene glycol is the most common
form of antifreeze. Check the UTV
Manufacturer’s recommendations when
selecting antifreeze. Most require one
specifically designed for aluminum
engines. There are types of antifreeze
have additives that inhibit corrosion.
Only mix antifreeze with distilled water.
Impurities in tap water may damage
internal cooling system passages.
