GENERAL INFORMATION

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).
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 intermix 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 surface 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 a mineral-based (Petroleum) oil into the
brake system. Mineral oil causes rubber parts in
the system to causing complete brake failure.
Coolant
Coolant is a mixture of water and antifreeze used to dissipate engine heat. Ethylene glycol is the
most common from of antifreeze. Check the UTV Manufacturer’s recommendations when selecting
antifreeze. Most require one specifically designed for aluminum engines. There types of antifreeze
have additives that inhibit corrosion.
Only mix antifreeze with distilled water. Impurities in tap water may damage internal cooling
system passages.
Cleaners, Degreasers and Solvents
Many chemicals are available to remove oil, grease and other residue from the UTV. Before using
cleaning solvents, consider how they will be used and disposed of , particularly if they are not
