What are the different types of octane gas?

octane gas comes in several different degrees, each number at a degree representing the resistance of fuel. The higher the octane evaluation, the slower ignition or burning. The most basic form of octane gas on the mass market in the United States is 87 octane. Most of the US gasoline stations will offer octane rating at different levels ranging from 87 to 92. Individual pumps usually offer at least two octanes, some offering up to five. This fuel is more stable than other types and can therefore be used in internal combustion engines. 87 octane fuel usually means that it consists of 87 % octane and 13 percent of some other type of fuel. This other type of fuel could be hexane, which is six carbon atoms connected together.

Theoretically, more than 100 octane fuels cannot be achieved, but there are boosters and refining skills that make fuel even more stable. Such gasoline can be given an assessment of more than 100 octane. This is not a factA statement of octan, but rather an equivalence evaluation that shows how stable fuel is.

The purpose of octane evaluation is to show how much fuel can be compressed before it ignites. 92 octane fuel will require more compression than octane 87 fuel. Some types of motors may have higher compression ratios and, as a result, require more stable fuel. The stability of octane and fuel shares direct correlation.

Many vehicles use 87 octane gases without problems, especially those with fuel injection. For cars sold in the US, most manufacturers design engines for 87 octane and recommend this class. This octan will also be the cheapest. The use of higher octane will not cause any damage to the vehicle, bumper or offer any advantage.

In some cases, higher octane gas may cost less than lower octane gas, at least for consumers. SomeIngredients such as ethanol can be included in higher octane gas. Ethanol fuel tax subsidies can actually use cheaper, although octane may be higher. Those who use ethanol can reach the gas station, but find that their number of mileage is reduced because ethanol does not burn as effectively as fossil fuels.

In general, the only time when higher octane gas may be required is when the vehicle has a high -performance engine. For example, cars that are advertised as a charged turbo may require higher fuel octane. The use of lower octane gas could cause motor knocking or poorer power. Drivers who are not sure what octan should use should check the owner of their vehicle. Older vehicles or equipment with carburetors may also require higher octane.
