Yea, not just old cars. We need it for our boats and dirt bikes and snowmobiles and chainsaws, and lawn mowers, and etc etc etc. dumb fucking idea to add more ethanol. Was on board with the trump train 100% until now.
Its not racing fuel. Ethanol actually makes less energy per unit of mass than ordinary gas. Nonetheless, if your tune properly for it (big injectors, ignition, etc) you can make good power because its effective octane is high and it burns cooler. But, real racing fuel has a high octane and a high Specific Energy (energy density).
