Have you ever wondered what all the letters and
numbers on an oil bottle mean? They stand for
different oil weights. For example, a bottle that
reads "SAE
30W", assures that the oil conforms to the SAE's
(Society of Automotive Engineers) oil weight or
viscosity standards. The "30W" represents the oil
weight, and
the lower the number, the thinner the oil. Use low
numbers in cold weather, higher numbers in warm
climates.
You can buy oils in single grades for warm or cold
weather driving. However, most people prefer
multigrades which suit your car during all seasons.
Multi-viscosity grades (for example, SAE 10W-30)
will provide a wider range of use and permit you to
drive from one climate extreme to another. They are
also
insurance against sudden temperature change in your
own area.
It is important to use the correct motor oil weight
to reduce wear on your engine. The optimum oil
weight for your car depends on the climate you live
in, your
vehicle manufacturer's recommendations, your driving
conditions and the maximum fuel economy you want out
of your car (the lower the weight of the oil, the
greater the fuel efficiency).
You can determine the best oil weight for your
vehicle by checking your owner's manual or by asking
a Jiffy Lube technician to recommend one for you. |
