Just like diesel engine, a gas engine is also an internal combustion engine. It runs on gas fuel like coal gas, biogas, landfill gas or natural gas. In America, the widespread usage of gas engine becomes the reason that the engine is known as gaseous fueled engine or natural gas engine. Generally speaking, the term “gasoline engine” refers to a heavy-duty industrial machine which works in a high fraction of 8760 hours per year. While the gasoline automobile engine hardly runs 4000 hours in its entire life. The good quality natural gas engine can typically own mechanical efficiency not more than 48%.

How to save money on gasoline?
When it comes to refuel your car with gas, you have so many choices. Either you can go to the national gas station for premium fuel which advertises widely or you can go to a local discount station to save few pennies a gallon on your pocket. At every station, different grades of fuel are available. Gas dealers always differentiate their fuel in quality due to competitions in the market. Because of gasoline prices hike due to tension in the Middle East and the weakening of dollar, saving money is becomes the matter of discussion on gas. There are some people who choose cheapest gas while some use premium grades. What is the difference between premium and cheapest gas?

Discount Gas: First of all, we discuss about discount gas which gets more demand at present. All gasoline engines sold in America meet their own standards. The main difference between the premium and cheapest gasoline is the detergents level. A minimum detergent level gas is available in all retail stations with discount. Detergent prevents residue buildup which needs to burn more gas and the valves work with less efficiency. That’s why in the long run, it costs you more. On the other side, premium gas fuel contains more detergent levels which prevent residue buildup. So, the less residue buildup on gas tank, the more fuel-efficiency on the engine.

Premium Fuel: Gasoline fuel comes in three grades at most gas stations; the regular unleaded and two high-octane grades. Since 1996, to remove toxic pollution, the leaded has been removed from all gas stations of US and then unleaded becomes the unnecessary component in the title. Regular graded gas comprises of 87 Octane. Gasoline can ignite spontaneously after compression. The higher the octane in gas, the more compression gasoline can take before ignition.

By 1980, the gasoline engines were less efficient than the today’s engines in terms of ignition and octane. Modern engines are fuel injected which overcomes most of the problem of former gasoline engines. Today, majority of vehicles are designed to support 87-octane fuel. Some supercars are designed to support premium gas fuels on their engines. Therefore, in order to keep your vehicle in properly running condition and to not violate the warranty, always use the fuel of grade which is suggested in the owner’s manual of the vehicle.
