what type of gas do vehicles use?

Question

there are so many types of gasses, i've been tryin to find out which one is for vehicles for a class project

Answer 1

most cars use regular unleaded which is usually around 87 octane (octane is the ability to reduce combustion chamber heat and pre-ignition also known as spark knock). this is fine for normal performance general transportation vehicles. next step up is middle grade (in warmer climates) which is around 89 octane. this is good for trucks, mild performance and older less technically advanced engines. next is premium which is around 91 octane. this is for high performance, high compression engines and does little or nothing for engines that do not require it although it does usually contain a better cleaning additive package. all of the fuels usually contain a small amount (5% or less)of alcohol, most of time in the form of ethanol. that brings us to E85, this is an 85% ethanol, 15% gas mixture which usually has about the same octane rating as mid grade or premium. this fuel can only be used in flex fuel or vehicles designed to use alcohol. E85 can cause damage to fuel systems that are not designed to use it. E85 is less expensive, but it is also less efficient due to containing less energy potential as measured in BTUs, meaning that fuel mileage and performance generally will not be as good as with gasoline. from there we have racing fuel, very high octane and usually contains lead. used for racing and aircraft engines. diesel fuel, trucks and cars with diesel engines only. LPG, liquid propane gas, require special modifications to vehicles that use it. natural gas, specially designed vehicles only. there is more but I'm tired and you need to do your own home work.

Answer 2

No, but it is stupid, and a waste of money. Unless the vehicle always needs supreme, it is not cleaner, better for the environment, or such, and it may even be worse for the environment. It is exactly the same, in every way, except price, unless the vehicle is one that always needs it. It is a total and complete waste of money to put supreme into a vehicle unless either (a) it is the only type of gas available, or (b) the vehicle is a vehicle that needs to have supreme always. If the vehicle does not need to have supreme always, then it will run exactly the same whether it gets supreme always, regular always, or some of each. The only harm is wasting money.

Answer 3

Your Science Teacher must have asked you a trick question.
The stuff we call "gas" isn't really a gas, it's a liquid, the full name is "Gasoline".
The British have a different name for the same liquid car fuel: "Petrol".
Gasoline is a parafin. You can impress your science teacher by memorizing and reciting the parafin series:Methane, Ethane,Propane,Butane, Pentane, Hexane (Benzine) , Heptane, Octane, Nonane, and Decane.

Gasoline contains mostly benzine and octane , the more ocatane is has, the higher it's octane rating.

Methane is used in City Busses, but it's called by it's abreviation ,LNG, for Liquified Natural Gas.

Propane is used for Barbecue Grills, and Butane is used for Cigarette Lighters.

Decane is a solid at room temperature, and is called Parafin, or wax, and is used for making candles.

Answer 4

Gasoline or petrol is a petroleum-derived liquid mixture consisting mostly of hydrocarbons and enhanced with benzene or iso-octane to increase octane ratings, used as fuel in internal combustion engines.

Most Commonwealth countries or former Commonwealth countries, with the exception of Canada, use the term "petrol" (abbreviated from petroleum spirit). The term "gasoline" is commonly used in North America where it is often shortened in colloquial usage to "gas". This should be distinguished in usage from genuinely gaseous fuels used in internal combustion engines such as liquified petroleum gas (which is stored pressurised as a liquid but is allowed to return naturally to a gaseous state before combustion). The term mogas, short for motor gasoline, distinguished automobile fuel from aviation gasoline, or avgas. The word "gasoline" can also be used in British English to refer to a different petroleum derivative historically used in lamps; however, this use is now uncommon.[1]

Answer 5

The 4 main types of petroleum based fuels, in order of potential energy are: Diesel, Gasoline, LPG (liquid petroleum gas) and compressed natural gas(CNG). Other forms of "fuel" are: Bio-diesel (vegetable oil), Ethel alcohol, Hydrogen and stored electrical energy (battery's charged by something else which could include all of the above and sun ,wind and nuclear energy)

Answer 6

lets see just plain old gas with octane ratings of 87/91/93
diesel most heavy duty pickups use and big trucks. LP gas for alternative fuel vehicles and flex fuel which means gas and ethanol mix.

Answer 7

I use used frying oil for fuel,its free.Diesel Mercedes.

Answer 8

gasoline (different octane levels, go to your nearest gas station to see.)
Diesel
Ethanol
Vegetable oil (it's replacing diesel)

Answer 9

Unleaded? Not really sure what ur asking.
