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.
