Motor oil is one of the most important fluids in
your car's engine. A high quality oil must:
Lubricate: This is motor oil's most important job:
to prevent wear and scuffing of engine parts by
coating every moving part with a protective film
that reduces friction.
Clean: It is essential that your motor oil cleans
your engine, as well. Soot, ash, acids and moisture
form sludge and resins that can become baked onto
engine parts and prevent normal performance and
result in wear.
Seal: Your motor oil coats the uneven surfaces with
a film that is about .001 inch thick. It's not much,
but it's enough of a seal to prevent loss of power
in your engine.
Cool: Only 60 percent of your engine's cooling job
is achieved by water or air. The rest is cooled by
motor oil.
Despite advances in motor oil technology, no oil
will perform indefinitely. Motor oil becomes
contaminated with combustion by-products, dirt and
water vapor,
causing its chemical additives to wear out. Most
people drive under conditions more rigorous than
mere freeway driving (for example, stop and go
driving, dusty
conditions and high temperatures). These require
more frequent oil changes.
Regular oil changes lead to longer engine life. For
maximum engine life, Jiffy Lube recommends changing
your oil and filter every three months or 3,000
miles. |
