Besides, ethanol increases the octane rating too. In Oklahoma, 87 octane gas w ethanol is around 91 octane and a dime cheaper than regular gas. Why buy stuff that could be potentially harmful to ur fuel system to get a little more power. Most peoples trucks, which are stock or slightly modified don't need anything more than 87 octane.
