Many car engines run on gasoline. If the octane is low, the engine will knock. If it is high, the engine will not knock, which means that sometimes it will make a knocking sound as you drive along. It also might keep running when you turn off the key to the car. With high octane, the engine also starts easier. It is more expensive to make high octane fuel. Lower octane fuel gets better milage. There are two organic chemicals: isooctane and heptane. Isooctane is a good fuel for cars. It is rated at 100 octane. Heptane is a bad fuel for cars. It is rated at zero octane. When gasoline is made, they need to make a certain octane. They put the gasoline in a car engine. They then run the car with a mixture of isooctane and heptane. They find the mixture that matches the batch of gasoline. That is the octane rating of the new batch of gasoline.

What is the measure of the antiknock properties in a fuel?
octane number
What is the octane number?
The octane number is a measure of performance of a fuel. It is measured relative to pure isooctane which is given an arbitrary value of 100. It is possible for fuels to have an octane number higher than 100. The higher the octane number the more compression it takes for the fuel to detonate. Higher octane fuel is used usually in high performance vehicles where the engines have higher compression ratios. If the octane number of a fuel isn't high enough it can lead to engine knocking this is where the fuel detonates before the fuel is at its maximum compressive state in the engine, this can cause damage and lower performance.
What is the octane number of aviation fluid?
100 octane. This is why aviation fuel (avgas) is typically called 100LL, which stands for 100 octane, low lead.
How do you measure octane in fuel?
with an octane mesurer
What is the Measure of the antiknock properties in fuel called?
I think it might be 'octane number'
What is octane number?
The amount of resistance that a fuel has to detonation. The higher the number, the less likely it is that a particular fuel will detonate in a particular engine. The number is as compared to a standard fuel (not necessarily gasoline)
How many carbon atoms are present in one molecule of fuel oil?
if your fuel is an octane, then the number of carbon atom is 8.
What is fuel octane on dodge ram 1500?
87 octane
What octane fuel do I use in a Chevrolet suburban?
87 octane
How do you separate a high grade racing fuel from normal fuel?
it is based on Octane levels, you have your standard 89,91,93 octane regular gas, and racing fuel is closer to 117 octane hope that helps
What is high octane fuel?
Regular unleaded fuel is 87 octane. High octane fuel is any fuel higher than regular. 89 and 91 octane being the most common the consumer can buy. High octane fuel is not needed in most cars and is a waste of money if your car does not need it. It provides no benefit whatsoever in a vehicle designed to run on Regular. Octane is only a measure of how well the fuel prevents pre-detonation in a high compression engine.
What Octane fuel do you put in a Audi A4 1.8T?
91 octane
