Did you know gas use
to be sold to treat lice? Back in the day it was bottled and sold in drug
stores. With people taking to the road, gas went from bottles to tanks! But
with 95 percent of American households owning at least one car, how many know how
gas is graded? Who’s over paying?
You don’t have to
drive to your gas station to find out – stay seated and read on!
There are three main
types of gas grades available in the US. They are defined by their octane
levels:
regular (87 octane)
plus/midgrade (89 octane)
premium (93 octane)
Octane is defined by
how easy it burns (combusts). The lower the octane level, the easier it burns.
In your car manual,
the manufacture typically states the “recommended grade” to use. However, according
to USAToday, “The main advantage of premium-grade gas is that it allows
automakers to advertise a few more horsepower by designing and tuning engines
to take advantage of premium's anti-knock properties.”
With engineers agreeing
that regular gas in a premium engine creates a barely noticeable difference in
power loss, car owners can save money at the pump by using regular gas. Using
high-octane gas in a car designed for regular creates a very little difference
for your money. Over time, if knocking occurs, it’s
recommended that you use a higher grade of gas.
