Lubricants and Fluids
Periodic lubrication help ensure a long service life for any type of equipment. Using the correct
type of lubricant is as important as performing the lubrication service. Although in an emergency the
wrong type is better than not using one, The following section describes the types of lubricants most
often required. Make sure to follow the manufacturer’s recommendations for lubricant types
Engine oils
Engine oil for four-stroke the UTV engine use is classified by two standards: the American
Petroleum Institute (API) service classification. The Society of Automotive Engineers (SAE) viscosity
rating Standard classification
The API and SAE information is on all oil container labels. Two letters indicate the API service
classification. The number or sequence of numbers and letter (10W-40SG for example) is the oil’s
viscosity rating. The API service classification and the SAE viscosity index are not indications of oil
quality.
The APL service classification standards, The first letter in the classification S indicates that the oil
is for gasoline engines. The second letter indicates the standard the oil satisfies .
The classifications are: MA (high friction applications) and MB( low frication applications).
NOTE
Refer to Engine Oil and Filter in
Chapter Three for further information
on API, SAE classifications.
Always use an 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 have a
higher number. Engine oils fall into the 5-to50-weight range for single-grade oils.
Most manufactures 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.
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).
