Stopped off to fuel on my way home. The gas station has unl88 fuel. Did a quick read on it. Has higher ethanol in it, however better fuel economy and to me throttle response. It was less expensive by nearly .25 cents a gallon.
Any comments on this stuff, seeing about 3mpg better since I filled up.
Gas UNL88
Re: Gas UNL88
Alcohol as a fuel requires about twice as much volume to create the same amount of thermal energy. When I put E85 in my cars the fuel economy drops. It costs less per gallon, but the MPG was less. It's kind of a trade off. I kind of look at as it will take "X" amount of thermal units (BTU's) of energy to travel, say 100 miles. It would take more alcohol to travel the 100 miles versus gasoline.
Our cars (and any E85 capable vehicles) are equipped with larger injectors to accommodate the higher flow rates attributed with using an ethanol based fuel. The fuel systems are equipped with octane and alcohol sensors to adjust the fuel flow rate and spark accordingly.
