Proper Lubricant Waste Disposal:
When performing service maintenance on the engine, transmission or rear axle, waste fluids and fil-
ters should be properly disposed of or recycled. Package used oils, antifreeze and other fluids in sealed
containers. In many cases used oil is accepted free of charge at county disposal sites. Waste fluids are
toxic to pets and other animals. Waste fluids should not be left in open containers. The sweet odor
of antifreeze is attractive to pets, but highly toxic.
CAUTION:
Properly dispose of used antifreeze and waste oil. Animals like the sweet odor of
antifreeze and may ingest it if left in open containers. Wipe up any fluid spills.
Pets may lie in puddles of fluid, many of which are irritants and can cause severe
chemical burns if not properly washed.
Lubricant Classification:
Lubricants are manufactured in many forms for a variety of applications. There are many different
oil and grease consistencies each with a designed application. To properly select a particular type of
lubricant for a specific application, the component must be evaluated. Component stress loads, ambi-
ent temperature, working temperature and environmental exposure are just a few of the variables to
consider. Select the proper lubricant for its intended application. As an example: selecting high viscosi-
ty grease to lubricate a lock cylinder results in sluggish lock cylinder operation especially in a cool
environment. Conversely, using graphite to lubricate a component that is under extreme temperature
and load will result in component failure.
Grease ratings and their base compounds are especially important when selecting a lubricant
type for an intended application. Some grease compounds are manufactured for multi-use application.
These are acceptable if the grease rating is in accordance with the manufacturer’s recommended lubri-
cant type and rating.
Lubricants:
Many chassis components require lubrication. The types of lubricants used will vary with the appli-
cation of the component. A component may fail prematurely due to lack of lubrication or from using an
incorrect lubricant type. The component manufacturer usually recommends a particular type of lubricant
with a minimum approval rating. Most lubricants are tested under strict guidelines set by the ASTM
(American Society for Testing and Materials). The NLGI (National Lubricating Grease Institute) helps
disperse information to the grease production industry. Grease containers usually have an approval rat-
ing by the SAE (Society of Automotive Engineers), Mil Spec (Military Specification), API (American
Petroleum Institute) or by other recognized and accepted organizations. The correct lubricant type with an
approved specific rating must be used whenever applying, changing or adding any lubricant. When
purchasing lubricants for a specific application be sure the label affirms the type of lubricant required
with the tested rating by the term "meets or exceeds" in accordance with the manufacturer specifi-
cations.
