“Octane number”, is a measure of the ignition quality of fuel. ... In India unleaded petrol typically has octane ratings of 87, whereas premium fuel has an octane level of 93–94. Speed 97 is available for premium cars that require mandatory high octane fuel.

Premium fuel is typically rated at 91, and Super is usually rated at 93. Those numbers are actually telling you how much octane is in that fuel: 87% octane for your Regular gasoline; 91% octane for Premium, and 93% for Super. ... Regular gas has less octane than Super gas, and therefore requires less compression.

"Power petrol" has a higher octane number than ordinary petrol/gasoline. ... Very high-performance vehicles may gain some benefit from the higher octane rating because it permits them to run with higher compression ratios and more advanced ignition timing, with a resulting gain in horsepower.

One obvious difference is the price. According to the U.S. Energy and Information Administration premium fuel nationally averages about 60 cents more per gallon than regular gasoline, and 25 cents more than midgrade gas.

Race fuel has a much higher octane than pump gas because those engines have higher compression ratios. Most new cars today can run on regular 87 octane because those engines are designed for that kind of fuel. Race cars, however, tend to have higher compression ratios so they thrive on the higher octane fuels.

Generally less easily. Diesel vehicles naturally have more toque than petrol engines do. This therefore means that they are less likely to stall when taking off at the lights etc than a petrol engine. Petrol engines though can naturally take off faster than diesels though.

Though the diesel variant has a higher torque than the petrol, it does so on a lower rpm due to which shifting is necessary sooner than that on the petrol. Thus the petrol produces more power and accelerates from 0 to 100 quicker.

So why do the terms for the fuel differ? Firstly – gasoline and petroleum are the same thing* – and in well over 99% of occasions you're likely to encounter it, it won't be a gas. As anyone who has refuelled a vehicle knows, the tank is filled with liquid.

So, what's the difference between premium and regular gas? Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates.

In a sense, octane slows down combustion, it delays it. Gasoline needs to have an octane rating of 87-91 to fit today's car engines. Diesel fuel has an octane rating of 25-40. Mixing 2% diesel fuel into gasoline will lower the overall octane rating by 1 point.

Simply stated, premium gas has a higher octane level than regular gasoline. The octane rating of gasoline determines how likely it is for engine combustion to occur at the wrong time. The higher the octane level, the less likely the combustion will occur at any time other than when it was designed to occur.

Gas oil (also popularly known as red diesel) is the same fuel as normal road diesel but with one difference. Gas oil has been given a red marker dye so VOSA or the police can easily trace the fuel if it's being misused. ... It should not be used in vehicles that use public roads.

Key Difference: Petrol and gasoline are two different terms for the same fuel that is used in an internal combustion engine. ... The term 'petrol' is used in UK, India and a few other places, while 'gasoline' or 'gas for short' is used in the United States. That is the only difference between the two terms.

Most gas stations offer three octane levels: regular (about 87), mid-grade (about 89) and premium (91 to 93) but we've broken down the facts about each so you can make the right choice at the pump. Regular Unleaded Gas- Typically the cheapest per gallon, regular gas is the most commonly used octane.

The price of petrol vs diesel Diesel cars tend to be more expensive than petrol: a petrol car is usually between £1,000 and £2,500 cheaper than an equivalent model of diesel car. While petrol cars are cheaper than diesel, this difference will be more or less significant depending on the overall cost of the car.

The most efficient petrol is the C 200, which returns up to 44.1mpg thanks in part to the EQ-boost mild-hybrid tech. The C 180 manual isn't far behind at 43.5mpg, but you'll have to work it much harder.

“Regular” fuel in most parts of the USA has an octane rating of 87. “Premium” (when there is only 1 choice above regular, is usually sold with an octane rating of 91–93. Mid-range upgrade gasoline has an octane rating of 89–91 This mid-range fuel is sold as “super”, as distinguished from “premium”.
