Article Body:
In the U.S., gas is the short form of gasoline, while in many
Commonwealth countries, it is known as petrol. Gas is a petroleum-derived
liquid mixture that consists of hydrocarbons and is used as a fuel in
internal combustion engines.

There are different types of gasoline in the fuel industry. Small
aircrafts use specially formulated, high-octane aviation gasoline, which
cannot be used for ground vehicles. Vehicles involved in racing use
specially formulated racing gasoline that has very low levels of benzene
and an anti-knock index of at least 100. Gasoline used for scientific
research has unusual properties, which depend on the nature of the
research. Cars with gasoline engines use E85 gasoline that is a blend of
85% fuel ethanol and 15% gasoline. The reason gasoline is added here is
to provide a good start and warm up performance to the car, which is
possible because of ethanol’s low volatility.

The diesel engine cars or cars with compression ignition engines use E95
gasoline that is a blend of 95% fuel ethanol and 5% gasoline. No more
than 5% gasoline should be added because this may lower the flash point
to unacceptable levels. E85 cannot be used in diesel applications, and
neither can E95 be used in gasoline engines because of the different
types of engines.

It is always better to buy gas during the coolest times of the day, like
early morning or late evening as this is when gas is found at its
densest. Gas pumps measure according to volume of gasoline and not
density of fuel concentration, so you have an advantage here. It is
better not to fill your gas tank to the top as overfilling results in the
sloshing over of the gasoline out of the tank. Gas has to be chosen
wisely for use in vehicles because some brands have greater economy due
to its better quality. It is always better to use brands that seem to be
beneficial. To save gas, it is better to avoid too much warming up of the
engine, even on cold mornings. About thirty or forty-five seconds of
warming up is more than enough. Avoid unnecessary starting and stopping
of the engine. You use the same amount of gas here as you would in idling
the engine for one minute. Use gas wisely, as it is an unrenewable fuel
source that will always be needed by mankind.
