OIL,
FILTERS AND FLUIDS
What Does It Do?
Critical
parts of your engine are lubricated, cleaned and cooled by your car's
oil and filter. Other specifically formulated fluids are used for
the operation and protection of systems and components such as brakes,
power steering, automatic transmissions, and cooling and axles. Your
car may also be equipped with a variety of filters including those
for the transmission, fuel system and interior ventilation.
Why Do I Need This Service?
Periodic
oil and filter changes keep your engine clean on the inside. Dust,
metallic shavings, condensation and even antifreeze can contaminate
motor oil. Additives, which break down over time, are also subject
to contamination. Other car fluids may require periodic replacement.
For example, the majority of automatic transmission failures are heat-related,
and automatic transmission fluid breaks down rapidly when subjected
to high temperatures. Your car owner's manual may specify periodic
flushing and filling of the brake hydraulic system because contaminated
brake fluid may lead to erosion and other problems in the hydraulic
system, especially, on cars with antilock brakes (ABS).
What is a Typical Service?
-
Change
oil and filter every 3,000 miles or three months.
-
Many
car manufacturers recommend extended oil drain intervals for some
drivers.
-
If
you regularly make short trips in your car, drive in stop-and-go traffic,
idle for extended periods, drive in dusty or dirty air conditions,
tow a trailer or live in a cold-weather region- stay with the 3,000-mile/three-month
schedule.
-
For
automatic transmissions, brakes, power steering and axles, vehicle-specific
fluids should be used.
-
Coolant
should be changed every two years or 24,000 miles on cars with ethylene
glycol antifreeze.
