Does it matter what gas I put in my car?
In general, it does not matter what type of gas one uses in a car. Most cars are built to run on economy gas, and giving them higher octane fuel is rather like giving a treat to an overstuffed dog. It’s not necessary, it provides no additional benefits, and it will cost more.
How much gas does starting the car use?
How Much Fuel It Takes. It takes about 1/2 teaspoon of gas to start the engine. The amounts can vary, depending on the number of cylinders in the car, but as an average guide it is accurate. The engine only needs enough fuel for the initial explosion within the cylinders. The more cylinders the engine has, the more fuel will be used for ignition.

It is better for your car to use 87, 88 or even 91-octane gas than to go too low. If you have a luxury car that needs premium gas, try to fill up before driving to a high-altitude location in case you cannot find a gas station that provides the octane you need.
What kind of gas does a car usually use?
Regular gasRegular gas (typically 87 octane) is one of the most common fuel types. Many car manufacturers recommend regular gas, and it's many drivers' go-to option. Regular gas is a budget-friendly gas option and is standard for many vehicles. Mid-grade gas (usually 88 to 90) is a specialty gas.
Does my car really need premium gas?

Does premium gas clean your engine?
No, premium gas isn't a secret sauce for cleaning your engine. The main concern in engine maintenance is carbon build-up, which can happen over time with all fuel types if you skip routine checks. The good news is that both regular and premium gas have detergents that can reduce carbon deposits to an extent.

Will mixing premium and regular gas mess up your car?
Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
What is the octane number for mid grade gas?
Mid-grade gas (octane number 89) splits the difference between regular gas and premium. But the added cost for this gas isn't necessary unless your vehicle manufacturer requires this octane number. You can easily spot these levels at the pump based on the numbers on the buttons used to select your gas.
What is the octane rating of unleaded gasoline?
You’ll see instructions like, “Use unleaded regular gasoline with an octane rating of at least 87 to 91, ” or “at least 91 to 95.”. In the former, premium could be seen as a recommendation (since the car is fine with “at least 87”), whereas it’s a requirement for the latter. For vehicles with high-compression engines or turbochargers (think sports ...
What About Diesel?
Diesel cars require fuel specifically formulated for their engines. This is because diesel engines utilize fuel differently than gasoline engines, injecting it only after air is compressed (in a gasoline engine, air is mixed with the fuel before compression) and forcing it to combust via pressure, rather than using spark plugs.
Why is higher octane better?
Higher-octane fuel does a better job preventing unnecessary combustion in your engine. In other words, it helps ensure your fuel burns evenly, which can keep your engine cleaner. You may have heard that using the wrong octane gasoline will cause engine knocks; that's typically due to irregular fuel burning. Though it's a very common issue, you wouldn't want to let it persist as regular knocking or pinging can cause engine damage.
What does RVP mean in gas?
Specifically, this involves the Reid Vapor Pressure (RVP) within the fuel. RVP determines how easily fuel evaporates. In the low-temperature winter months, gas has to be able to evaporate easily, so a higher RVP is needed. Unfortunately, the evaporation of gas isn’t good for the environment.
Why do gas stations use detergent?
That's because all filling stations obtain their gas the same way. Raw fuel arrives at a regional distribution center, and retailers purchase it there. Before selling it to the consumer, the gas stations blend in their own combination of detergent and/or additives to help your car run clean.

Although the difference may be slight, these engines generally develop more power and better fuel economy on higher-octane fuel. However, you won’t damage the engine or void your warranty by using regular gas. Our advice is to run a few tanks of both regular and premium and calculate your fuel economy. Decide for yourself if the differences in power and fuel economy, if they’re even noticeable, are worth the extra cost of premium fuel.
What If My Car Says RON 95 or RON 98?
Some European cars specify RON 95 or RON 98 — but don’t worry, you don’t have to look for 95 or 98 octane fuel. These are European octane numbers calculated using a different method than the one used in the United States. RON 95 is equivalent to 87 octane in the U.S., and RON 98 equals 94 octane; for the latter, 93 octane fuel should be sufficient. To put it simply, RON 95 means “regular,” and RON 98 means “premium.”

What is Octane Rating?
The octane rating on different grades of gasoline is a measurement of the fuel’s stability. Higher octane numbers mean greater stability. The greater stability indicates the gasoline’s resistance to preignition and the fuel’s ability to resist “knocking” or “pinging” during combustion. These sounds come from the air-fuel mixture detonating prematurely in the engine.
What is Flex Fuel?
E85 is a fuel designed for “flex-fuel vehicles.” It is composed of 85% ethanol and 15% gasoline. E85 pumps are clearly labeled at gas stations and typically have yellow nozzles.

How many vehicles use compressed natural gas?from newpowerpost.com
The Compressed Natural Gas vehicle market currently comprises of about 26 million vehicles, with China having around 6 million, Iran 4.5 million, India 3 million, Pakistan 3 million, with Brazil and Argentina at 2 million apiece. Natural Gas is mainly comprised of methane (CH 4 ). CNG vehicles require a second fuel tank to be installed, fuel delivery line, and a switch allowing the driver to choose between gasoline and CNG as the fuel. While most CNG vehicles suffer from slightly lowered engine power, and a shorter driving range on a single CNG tank, these vehicles do have lower emissions. CNG is also often a cheaper fuel per distance traveled, allowing the consumer to save on fuel prices.
What are fossil fuels?from byjus.com
Fossil fuels are the dead and decayed remains of plants and animals subjected to decades of pressure and temperature under the earth’s crust. Primarily fossil fuels are hydrocarbons. They are convenient and effective. They provide the calorific value required to fulfil our needs. Even though they are available in plenty right now, they are a non-renewable source of energy. The burning of fossil fuels is responsible for a large section of the world’s pollution index.
How many LPG vehicles are there in the world?from newpowerpost.com
According to the World LPG Gas Association, there are 25 million LPG vehicles currently in operation, with Turkey, Poland, and South Korea leading the world in its use. The composition of Autogas and Propane can vary slightly: Propane in North America is comprised of mainly propane molecules with three carbon atoms (C 3 H 8 ), while Autogas in Europe can have up to 40% Butane mixed in, with four carbon atoms (C 4 H 10 ). In the US, this is the same gas that is used for BBQ grills. Because LPG has a much higher fuel density than CNG, (25MJ/L versus 9MJ/L) and operates at a lower tank pressure (less than 2 MPa as a liquid while CNG is 20 – 25 MPa), it is inherently safer and each tank can go farther. Because LPG is also retrofitted like CNG and used in tandem with gasoline, LPG-gasoline vehicles can reach refueling ranges of 1000 km. The vehicles normally start in gasoline mode, and can then be switched over to LPG mode when the engine has been heated. This is to ensure that the LPG fuel does not freeze when expanding in the pressure reducer.
How does ethanol affect gasoline?from fuelfreedom.org

Premium vs. Regular
Your Local Gas Station vs. Name-Brand Gas
- There are more than 100,000 gas stations across the nation. Some of these are name-brand retailers (think Mobil or Sunoco). Others are generic or unbranded dealers (think that mini-mart by your house that doubles as a burrito joint). Despite the gulf between those guys and, well, Gulf, their gasoline isn't that different. That's because all filling stations obtain their gas the same way…
