Regular
Unleaded
– (Octane Rating 87 – Fastest burn, lowest detergent rating) These are the
general octane ratings according the government, they may differ slightly,
depending on where you live. The difference between these 3 types of gas is
their octane rating. The higher the octane, the slower the gasoline burns. The
higher the octane, the higher the detergent levels, which supposedly keep your
engine cleaner.
Mid-Grade
Unleaded
– (Sometimes referred to as Plus. Octane rating: 89 – Mid-burn and mid
detergent rating) If you own a car that takes premium gas, sometime you can get
away with using mid-grade as opposed to premium and save yourself some
money.
Premium
Unleaded
– (Octane rating: 93 – Slowest burn, highest detergent rating)
Diesel
Diesel
is less refined than unleaded gasoline, it’s about 18% heavier and it doesn’t
contain as many detergents or cleaning agents. Diesel cars or trucks need a lot
more lubrication than vehicles that require unleaded and as a result diesel is
a much “greaser” substance. Diesel fuel gets better miles to the gallon,
however it’s more expensive.
Ethanol
Bio-Fuel
– (85% Ethanol, 15% Gasoline) – Ethanol is a plant-based (mostly corn) fuel
that was originally developed to be more environmentally friendly and cheaper
than unleaded gasoline. Ethanol is a cleaner burning, less explosive, renewable
resource that supports local agriculture. Unfortunately the technology of
creating ethanol hasn’t been perfected enough to make it cheaper than unleaded
gasoline. It price fluctuates with the price of corn, and it also takes about
1.5 gallons of ethanol to do the same thing that gasoline does, essentially you
are getting poorer gas mileage.
Bio
Diesel
Bio-diesel
is created by chemically combing vegetable oil or animal fat with alcohol and
is designed to run in diesel engines. It is a renewable resource and less
toxic. There are about 600 places you can get bio-diesel across the
country.
