Have you ever wondered, why there are three types of gas
quality displayed on every gas station? And which one
is the best suitable for your car, and why?
Gasoline Grades: The classification of
gasoline is based on their "octane" ratings. They are graded as- Regular, Midgrade or Plus,
and Premium.
Regular (87): Octane rating is greater
than or equal to 85 and less than 88.
Midgrade/Plus (89): Octane rating is
greater than or equal to 88 and less than or equal to
90.
Premium (92): Octane rating is greater
than 90. What is octane rating?? Octane rating is used to rate the
volatility of gasoline. Lower the rating, easier it
is for the gasoline to burn. It is based on the antiknock
index, i.e. gasoline's ability to resist pre-ignition,
or engine knock. Hence, higher the octane rating, lesser
is the knocking. Checkout details at: http://theserviceadvisor.com/octane.htm Does it depends on the kind of
car or automobile? Yes!, most "powertrain control
modules" have inbuilt adjustments for octane rating,
for the most efficient burning of the air fuel mixture.
Engine octane requirement is set by the engine design,
which operates at optimum settings. Hence a higher octane
will have no extra affect on it. Once you pass the written test, you have to give a
eye test their itself. You will then be issued a temporary
permit. If you have never been licensed before, you
may use this permit to practice driving with an accompanying
adult, who is 25 years of age or older, with a valid
state license. It is illegal for you to drive alone.
Now you might take classes from some Instructor. Once
you are comfortable in driving, you can fix up an appointment
over the phone, for the road test. What should I use? There is no advantage in using a
higher octane fuel. Stick to the manufacturer's recommendation
for fuel requirements, unless knocking occurs. If your
engine knocks because of the conditions you encounter,
use a higher octane fuel.
It is not true that higher the rating, better is the
gas. You will be just throwing away your money for the
higher octane fuel. For most cars the right octane
is "Regular".
Read your Car'0s manual, and use the recommended gasoline
for normal operation of the vehicle. |
