Hawaii Ethanol Fuel Information

In most gasoline today, ethanol has been incorporated as an additive with a percentage of 5, 7, and 10 also known as E-5, E-7, and E-10 respectively, in which cases at not more than 10% will be generally safe for vehicles that uses unleaded fuel. Commonly, this fuel uses a mix of 10% ethanol, 90% gasoline, while in some other circumstances a 5% of other chemical ingredients are added to increase mileage.

Another mixture of the Ethanol will be the E-15; this contains 15% ethanol and 85% gasoline, and the maximum amount of ethanol that most of the car manufacturers recommend, though it is possible that one can get higher percentages without any problems.

A mixture of E-20 is common in Thailand with tax reductions. The E-20 fuel is for the usage of E-20 engines.

The 6th mix kind of mixture is most commonly used in Brazil-The E-25, 25% Ethanol, 75% Gasoline. The Flexible-fuel vehicles (FFV), which are deigned to take higher concentrations of Ethanol, will require this kind of fuel alongside with the E-20,

The E-85, with an octane rating of 105 is the highest ethanol concentration found within the US. In the US, the E-85 does not necessarily contain exactly 85% ethanol because of the cold climate during winter. A small amount of gasoline will be required for the engine to start.

The E-95 contains 95% ethanol with 5% ignition improver. As opposed to the gasoline engine, the diesel engine that uses this fuel uses the power of compression to ignite the high-temperature E-95 Fuel.

The last is the E-100 which is the highest concentration achieved with 4% water, most commonly used in Brazil and Argentina. This fuel is also known as Hydrated Ethanol, which at temperatures below 15 degrees will require gasoline to ignite within the engine.
